1. Check Case Studies and Past Results
When evaluating an SEO professional, their track record speaks volumes. A thorough review of case studies and past results can provide valuable insights into their capabilities. Be sure to look for detailed, verifiable information and follow up with client references to confirm their claims.
Ask for Complete Case Studies
A solid case study should cover all the essentials: the client’s starting point, the challenges faced, the strategies implemented, and measurable outcomes like traffic growth, improved rankings, or increased conversions. Look for specific data and clear timeframes to gauge the impact of their work.
Pay close attention to the methodology outlined in the case study. A competent professional should clearly explain how they diagnosed issues and devised solutions. Be cautious of anyone who leans on vague descriptions or claims to use "secret techniques."
For example, Moneta Group’s case study is a great benchmark. Their SEO expert delivered a 326% growth in net organic keyword portfolio, a 164% increase in organic keywords ranking in positions 1-3, and a 23% boost in Google Analytics goal completions. This was achieved through tactics like local SEO, competitive analysis, and content optimization.
Another standout example is DesktopReady. Their SEO efforts resulted in a 409% increase in users, a rise in backlinks from 822 to 1,340, and a surge from 4 to 468 terms appearing in SERP rankings. These results were driven by technical SEO audits, content creation, and social media optimization.
Once you’ve reviewed such case studies, take the next step: verify these claims by contacting the clients directly.
Contact Past Clients for Verification
Case studies can sometimes exaggerate or omit key details, so it’s crucial to verify them by speaking with past clients. Ask the SEO professional for references – most reputable experts will have satisfied clients who are happy to share their experiences.
When you reach out, ask specific questions about their working relationship. Did the professional meet deadlines? Were they communicative and transparent? Did they deliver on their promises? These details can give you a clearer picture of what it’s like to collaborate with them.
You can also use tools like Ahrefs‘ Site Explorer to validate some claims, such as traffic growth or keyword rankings. While you won’t have access to private analytics data, you can cross-check public metrics for consistency.
Find Experience in Your Industry
Industry-specific experience can make a big difference. An SEO professional familiar with your market will already understand its competitive dynamics, customer behavior, and effective optimization strategies. They’ll also know which keywords and content approaches resonate with your audience.
Look for case studies from businesses that share similarities with yours – whether in size, industry, or target demographic. For instance, Happy Ears Hearing Center saw a 245% increase in total organic keyword rankings, a 396% jump in organic traffic, and a 44% boost in local conversions.
Different industries often require tailored strategies. Local businesses need a distinct approach compared to national e-commerce brands, and B2B companies face challenges that differ from those of consumer-facing businesses. An SEO expert with relevant experience will understand these nuances from the start.
That said, strong results across diverse industries can also signal transferable skills. Take Career Group Companies as an example: they achieved a 43% increase in job listing page views from organic traffic and a 71% rise in entrances from organic searches through keyword expansion and data-driven tactics. This demonstrates adaptability and a solid grasp of SEO fundamentals.
Ultimately, effective SEO requires a well-rounded approach:
"It’s not the best content that wins. It’s the best promoted content that wins." – Andy Crestodina, Co-Founder of Orbit Media
This quote underscores the importance of finding professionals who excel in both content creation and promotion. The most successful strategies combine these elements seamlessly, ensuring that great content gets the visibility it deserves.
2. Verify Certifications and Background
Beyond reviewing case studies, checking certifications and professional backgrounds can solidify your confidence in an SEO expert’s abilities. Certifications indicate that the individual has dedicated time to learning the latest practices and trends, ensuring they’re equipped to handle your project effectively. These credentials act as proof of their commitment to staying informed in a constantly evolving industry.
Check Official Certifications
Certifications from reputable sources validate an SEO professional’s understanding of core concepts and their ability to adapt to changing algorithms. They also signal dedication to professional growth. For clients, this means the expert takes their craft seriously and is willing to invest in formal learning.
When evaluating certifications, prioritize those from trusted platforms. For example:
- Google Analytics and Google Search Console certifications are foundational, as these tools are key to most SEO strategies.
- Additional certifications from platforms like Semrush Academy, Moz, HubSpot, and Yoast are widely respected and add credibility.
Here’s a quick overview of some popular SEO courses:
| Course | Platform | Cost | Time Commitment |
|---|---|---|---|
| SEO Course for Beginners | Ahrefs | Free | 2 hours (14 lessons) |
| Semrush Academy’s SEO Courses | Semrush Academy | Free | 1-4 hours |
| SEO for Beginners Training | Yoast | $99/year | 2 hours (20 lessons) |
| SEO Specialization | UC Davis (Coursera) | Subscription/Paid | 5 months (6 hours/week) |
| ClickMinded SEO Course | ClickMinded | $999 | 5-6 hours |
While shorter certifications can showcase breadth of knowledge, more comprehensive programs like UC Davis’s SEO Specialization often provide deeper insights. Look for a balance: certifications that emphasize practical applications are often more useful than purely theoretical ones.
It’s also worth noting that certifications alone aren’t enough. A combination of formal training, real-world experience, and proven results is the ideal mix when evaluating a professional’s capabilities.
Look at Professional Profiles
A professional’s online presence can reveal a lot about their skills and credibility. Start with their LinkedIn profile, which should highlight their certifications, work history, and connections. Then, examine their personal website – it’s essentially a live demonstration of their SEO abilities. Ask yourself:
- Does the site load quickly?
- Is it mobile-friendly?
- Does it rank well for relevant keywords?
If an SEO expert’s own site performs poorly, it’s a major red flag.
Additionally, check whether they actively share insights through blogs, social media, webinars, or speaking engagements. These efforts not only showcase their expertise but also reflect their passion for the field. A strong professional network and connections with other respected SEO experts or agencies can further indicate credibility.
Check Industry Involvement
Active participation in the SEO community is another sign of a professional’s dedication to staying current. SEO evolves rapidly, with Google rolling out thousands of algorithm updates each year. Professionals who attend conferences, workshops, or continuing education programs demonstrate their commitment to adapting to these changes.
Major SEO events like SMX, Pubcon, and MozCon attract industry leaders and those eager to learn from them. If a professional has spoken at such events, it’s an even stronger indicator of their expertise.
Ask potential SEO partners about their approach to staying up-to-date. For example, how do they adjust strategies based on recent algorithm updates? Do they attend webinars or contribute to industry forums? Their engagement in ongoing discussions about best practices often reflects their dedication to professional growth.
As Lisa Gevelber, Founder of Grow With Google, explains:
"Digitally advanced businesses report 20 times better customer acquisition rates. Yet almost half (49%) of small businesses still lack the information and skills needed to use digital tools. Filling these skill gaps can help fuel growth for American businesses while creating new opportunities for workers."
This highlights the importance of partnering with SEO professionals who are not only certified but also committed to continuous learning. By combining verified credentials, a strong online presence, and active industry involvement, you can confidently assess an SEO expert’s qualifications and potential impact on your business.
3. Review Campaign Results and Methods
After reviewing certifications and case studies, the next step is to evaluate how results were achieved. Look for concrete data that demonstrates measurable outcomes. The best SEO professionals are upfront about their methods and willing to share the metrics that back up their success.
Ask for Performance Data
When assessing an SEO expert’s track record, specific metrics provide clarity. Avoid vague claims like "increased traffic" or "better rankings." Instead, request detailed data from multiple campaigns. Key metrics to analyze include organic traffic growth, keyword ranking improvements, SERP visibility, click-through rates (CTR), and conversion rates. For instance, while the top organic search result can achieve a CTR of 31.7%, site-wide and individual page CTRs are often much lower.
You should also ask for numbers on new leads, conversions, revenue, and customer retention. These metrics should align with any case studies you’ve reviewed. Additionally, request comparisons that showcase month-over-month growth, seasonal trends, and how they responded to traffic drops or algorithm changes. Don’t forget to examine technical SEO metrics like page loading speed, mobile usability, and reductions in crawl errors – factors that contribute to long-term success.
Once you have the performance data, dig deeper into the tools and strategies used to achieve those results.
Learn About Their Tools and Methods
Top-performing SEO professionals rely on a variety of tools for tasks like keyword research, backlink analysis, technical audits, and competitive research. For example, Semrush is a popular all-in-one platform for research and audits, while Ahrefs is valued for its in-depth single-site SEO insights. Other must-have tools include Google Analytics 4, Google Search Console, Screaming Frog (to identify technical issues), and Surfer (for AI-driven content optimization).
The ability to turn raw data into actionable strategies is key. When evaluating their methods, ask how they confirm the accuracy of their data across platforms and how they use it to create effective plans.
With their tools and methodologies understood, it’s important to see how they handle the ever-changing landscape of search algorithms.
Test Their Response to Algorithm Changes
SEO is constantly evolving, with search engines like Google introducing frequent updates. In 2023 alone, Google rolled out 4,781 algorithm changes, and the March 2024 Core Update reduced low-quality content in search results by 45%. This highlights the need for SEO professionals who can adapt quickly when updates occur.
Ask how they stay informed about algorithm changes and how they respond to them. A skilled expert will have a clear process for identifying affected pages and diagnosing performance shifts. They should monitor key factors like content quality, traffic trends, technical SEO issues, and backlink health. Tools such as Google Search Console, Semrush, and Ahrefs are commonly used to track ranking and traffic fluctuations.
James Weiss, Managing Director at Big Drop, puts it this way:
"Trying to outsmart a search engine is like playing chess with a mirror – winning the game before it can reflect your next move is futile. But, understanding when and why changes happen can become strong indicators of how to mitigate loss of ranking, and can help you keep apace."
Look for professionals who prioritize trust, relevance, and user-focused strategies over quick fixes. Ask for examples of how they’ve helped clients recover from penalties or other setbacks. Their ability to quickly identify problems, implement solutions, and monitor recovery can make all the difference in protecting your website’s long-term performance.

4. Check Link Building Methods
Link building is still one of the most important elements of SEO, but it can be a double-edged sword. Backlinks act as "indicators of authority" in Google’s eyes, helping to establish a page’s relevance and credibility. However, not all backlinks are created equal, and using the wrong strategies can harm your website’s rankings instead of boosting them.
Check Backlink Quality and Relevance
When evaluating an SEO professional’s link-building strategy, it’s crucial to prioritize quality over quantity. A handful of high-quality backlinks from reputable websites will always outperform a large number of low-quality ones. To assess quality, focus on factors like relevance, the authority of the linking site, where the link is placed, the anchor text used, and whether the link adds editorial value.
Ask the SEO professional for examples of backlinks they’ve secured for past clients. Then, use tools like Moz Link Explorer, Ahrefs, or Google Search Console to verify the quality of these links yourself. Links embedded in the main body of content tend to carry more weight than those placed in footers or sidebars. A healthy backlink profile should also include a mix of dofollow and nofollow links for a natural appearance.
Take Nick LeRoy’s guest post on the Moz blog as an example. By including links to his website and newsletter, he gained a valuable dofollow backlink from a respected site within his niche. This kind of thoughtful, content-driven link building lays the groundwork for avoiding risky practices.
Make Sure They Avoid Low-Quality Sources
It’s equally important to ensure that the SEO professional avoids harmful link-building tactics. Practices like using link farms, automated tools, spammy blog comments, irrelevant forum posts, low-quality directories, private blog networks (PBNs), and hidden link schemes can do more harm than good.
Consider the case of RV Obsession. In May 2021, the site experienced a drop in organic rankings and traffic after working with a provider who built low-quality backlinks. An audit revealed that many of these backlinks had been removed or converted to "nofollow", and the site’s spam score had increased. By disavowing the problematic links through Google Search Console, the site managed to recover, with keyword rankings improving and organic traffic reaching 26,000 visitors. As Google’s John Mueller advises:
"Disavow links that were really paid for (or otherwise actively unnaturally placed), don’t fret the cruft."
This case highlights why natural, content-driven link-building strategies are far more effective – and safer – than manipulative shortcuts.
Use Trusted Networks
Reputable SEO professionals often rely on trusted networks and platforms to secure high-quality backlinks. These platforms vet participants and provide a structured system to avoid spammy or low-quality links. For example, 3Way.Social offers a vetted network for link exchanges and guest posting. The platform evaluates link value based on metrics like Domain Authority, Traffic Volume, and Spam Score, ensuring fair and reliable exchanges.
With over 10,000 successful link exchanges, users of 3Way.Social report an average traffic increase of 20% and rankings that improve three times faster compared to traditional methods. When vetting an SEO professional, ask which platforms they use and how they assess potential link partners. A professional using trusted networks should be able to explain their process and share examples of successful collaborations.
Sophia Martinez, an SEO Manager, shares her experience:
"3way.Social revolutionized our SEO approach. Our site’s rankings have significantly improved thanks to its innovative ABC link exchange system. The platform’s high-quality partner network is unmatched."
The ABC link exchange system – where three websites link to each other in a natural, indirect pattern – avoids the pitfalls of direct reciprocal linking while still delivering the benefits of high-quality backlinks.
5. Compare Professionals Using a Clear System
When you’re choosing an SEO professional, having a structured approach can make all the difference. A clear comparison system ensures your decision is based on solid facts, not just a flood of proposals that can feel overwhelming.
Create a Comparison Chart
Using a comparison chart is one of the easiest ways to organize and evaluate key information. This approach helps you quickly identify each candidate’s strengths and weaknesses while ensuring you don’t miss any critical details. Your chart should focus on the factors that matter most to your SEO goals.
Start with the basics like certifications, case study results, campaign performance data, and link-building quality. Then, include criteria tailored to your business, such as industry experience, communication preferences, and pricing. Here’s an example of how a comparison chart might look:
| Criteria | SEO Pro A | SEO Pro B | SEO Pro C |
|---|---|---|---|
| Google Certifications | Analytics, Search Console | None verified | Analytics only |
| Case Study Traffic Growth | +42% in 8 months | +28% in 6 months | +55% in 12 months |
| Industry Experience | 3 years in e-commerce | 5 years general | 2 years e-commerce |
| Link Building Quality | High DA sites (70+) | Mixed quality (30-60 DA) | High DA sites (65+) |
| Monthly Fee | $2,500 | $1,800 | $3,200 |
| Communication Style | Weekly reports | Bi-weekly check-ins | Daily updates |
You can also add other factors like client retention rates, team size, or response times. Depending on your priorities, you might want to give more weight to certain categories. For example, if link building is a top priority, that should carry more influence in your final decision.
Once you’ve organized the data, the next step is to evaluate whether each professional adheres to industry standards and practices.
Select Professionals Who Follow Proper Guidelines
After reviewing the data, dig deeper into how each candidate approaches their work. It’s essential to choose professionals who follow ethical, white-hat SEO practices. Google’s algorithms favor high-quality, natural strategies while penalizing manipulative shortcuts.
Ask candidates if they can explain Google’s E-A-T principles – Expertise, Authoritativeness, and Trustworthiness – and how they incorporate these into their strategies. They should prioritize things like content quality, natural link building, and technical optimization, avoiding outdated tactics like keyword stuffing or excessive link exchanges.
Pay attention to how they set expectations. If someone promises instant results or guarantees first-page rankings in just a few weeks, that’s a red flag. SEO is a gradual process, and it typically takes 3-6 months to see meaningful improvements. Professionals who are upfront about this timeline and explain the process clearly are far more reliable.
When it comes to link building, look for candidates who use vetted networks and platforms to secure high-quality backlinks. For example, professionals leveraging platforms like 3Way.Social can create natural linking patterns that avoid penalties from direct reciprocal links. This kind of thoughtful, modern approach indicates they’re staying current with SEO best practices.
Lastly, ensure the SEO professional you choose has strategies in place to adapt to algorithm updates. Search engines are constantly evolving, and your SEO strategy should evolve right along with them.
Conclusion: Main Points for Vetting SEO Professionals
Finding the right SEO professional isn’t just about flashy promises or impressive portfolios – it’s about digging deeper to understand their approach to both success and setbacks. SEO is an ever-changing field, requiring professionals who can adapt to algorithm updates and seize unexpected opportunities.
Start by revisiting case studies and client feedback. Dive into traffic data and ask how they’ve tackled challenges in the past. As Pedro Dias explains:
"A skilled SEO professional is the individual that has the necessary experience to handle complex problems and present solutions in a way that is intuitively simple and logic. Usually, an experienced individual doesn’t rely on checklists, because they’ll know there are countless ways to solve the same problem. The level of expertise can be assessed best by presenting a problem and observing how the professional approaches its resolution."
Certifications and technical expertise are good starting points, but they’re not the whole picture. Ask how they handle complex SEO scenarios. The best professionals can simplify complicated concepts into clear, actionable steps.
Another critical area to evaluate is their link-building strategy. Ethical, white-hat methods are a must. For instance, professionals using vetted networks like 3Way.Social showcase modern practices by leveraging AI-powered domain matching and secure link exchanges – tools that align with current SEO standards.
Communication and adaptability are just as vital. Your SEO expert should provide regular updates, clearly outline their strategies, and adjust their approach based on performance data. Mercy Janaki, Director of SEO Operations at Webenza, emphasizes this point:
"To spot a skilled SEO pro, don’t just focus on past wins like page speed or backlinks. Pay attention to how they tackle problems. Look for someone who’s adaptable, thinks smart, and can explain their strategies clearly. Skills in adapting to change and consistently delivering results are what you should seek in an SEO expert."
Lastly, prioritize the quality of experience over the sheer number of years in the field. What matters most are the skills and insights gained from past projects. A strong SEO professional combines strategic thinking, ethical practices, and consistent results while staying ahead of industry trends and algorithm updates. These are the qualities that set the best apart.

Why are certifications and active industry participation important when evaluating an SEO professional?
Certifications and active participation in the SEO field are strong signals of a professional’s expertise and dedication to staying current.

These elements combine to build trust, showcase dependability, and ensure they are equipped to deliver campaigns that drive real results.
What risks come with outdated or unethical link-building strategies, and how can I ensure my SEO expert uses safe practices?
Using outdated or shady link-building tactics can seriously hurt your website. Penalties, plummeting search rankings, and a tarnished reputation are just a few of the risks. Techniques like spammy links or private blog networks (PBNs) might seem tempting, but they often result in long-term damage to your SEO efforts.
To protect your site, make transparency a priority when working with an SEO professional. Ask for regular updates on their strategies and ensure they stick to white-hat techniques – like crafting quality content and earning genuine backlinks. Steer clear of manipulative practices that could put your site’s credibility and performance at risk.
