If you’re seeking out the best technical SEO agencies, chances are two things are true:
- You already know a thing or two about search engine optimization.
- Your website has some issues, whether that’s a drop in traffic, a multitude of 404 errors, or poor rankings despite good content.
Technical SEO is critical because it’s what ensures search engines can navigate and understand your website, which directly impacts your online visibility. You can have the best content in the world, but if it can’t be accessed due to broken links or redirects, you’re essentially throwing time and money out the window.
There are a lot of technical SEO agencies, so the following list is broken down by each agency’s strength. For example, some are better for local SEO vs. enterprise SEO. Others are best for specific industries or resolving certain technical issues.
Whatever your situation, I hope you find this list helpful in narrowing down your options based on varying differentiators. Technical SEO errors certainly aren’t something you want to sleep on.

5 qualities of the best technical SEO agencies
Perhaps you know you need a technical SEO agency but your knowledge stops there. It can feel daunting to try to pick a reliable SEO partner because, for a lack of a better phrase, “You don’t know what you don’t know.”
Here are some top traits to look for when seeking out the best technical SEO agencies.
1. Technical SEO expertise
First up: they need to have expertise specifically in technical SEO. Technical SEO is different from the general SEO umbrella. Make sure their website explicitly calls out the technical aspect as a service.
Even if you don’t know much about the tech side, there are still some questions you can ask to get a sense of their technical know-how. Consider asking:
- What is your process for conducting a technical SEO audit?
- How do you address crawl errors and crawl budget issues?
- What’s your approach to structured data?
- What are some examples of successful technical SEO projects you’ve completed?
- What tools do you use during a technical SEO analysis?
2. Comprehensive SEO audits
The best SEO companies offer in-depth technical SEO audits to get a full picture of changes that could impact your results. This includes reviewing your:
- Website performance
- Site architecture
- Title and URL optimization
- Internal linking structure
- Site indexation and crawlability
Consider asking for a list of everything that’ll be included in your technical audit from multiple agencies to see who would take the deepest dive.
3. Mobile optimization
Considering more than 60% of organic search traffic comes from mobile devices, your site’s mobile optimization isn’t simply a nice-to-have – it’s essential. Ask your technical SEO specialist how they optimize for smartphones and tablets and what can be done to improve your users’ mobile experience. It may also be prudent, though still the early days here, to ask them about their strategy regarding LLMs and AI-based search visibility.
4. Good, transparent communication
Some agencies hand you a spreadsheet of highly technical data with no direction. Others simplify and prioritize the findings and keep you in the loop with regular progress reports so you can easily track what’s being done when.
If you want to get the best bang for your buck, choose a team that will educate you with consistent, transparent communication to make you part of the process.
5. Positive reviews and case studies
Most well-established technical SEO agencies have client reviews and case studies published across their site. Look for case studies specific to technical SEO that demonstrate a real return on investment, preferably in dollar signs.
If they don’t have a technical SEO case study posted, ask for one.
When should you bring in technical SEO experts?
Technical SEO professionals aren’t only useful when you know something’s broken. Here are a few other situations where technical SEO knowledge can be vital to SEO success.
Unexplained low traffic
If you’re experiencing low website traffic despite a strong content strategy and other SEO efforts, it could be due to technical errors. Things like slow loading times, broken links, and improper sitemaps can all impact your website performance.
If that’s the case, a thorough technical SEO strategy can help get you quickly back on track.
Low search rankings
Problems with moving up in search engine rankings can also be a direct result of technical SEO issues. If you feel like you’ve tried everything you can think of to no avail, a technical SEO audit is a logical next step.
Starting a website redesign
A solid SEO structure is the bedrock for a well-performing website. This means that any time you’re going through a website redesign, it’s worth it to proactively involve technical SEO experts to help you build a comprehensive SEO strategy from the ground up.
This could mean changing the content structure, sitemap, menus, and more to make your site easier for search engines to navigate.
Advancing your SEO techniques
If you’re looking to implement more complex SEO strategies like schema markup, structured data, or other advanced features to enhance your online visibility, it’s best to engage a technical SEO agency to ensure everything is implemented correctly.
Conducting a CMS migration
Transferring from one content management system to another creates all kinds of technical hurdles. For this reason, it’s less risky to leave it to tech experts who are better equipped to make the transition without taking your site offline.
Conclusion
Technical SEO can make or break your business goals, so it’s important to entrust it to the right partner. While there are thousands of technical SEO agencies out there, the agencies on this list stood out for specific reasons that can hopefully help narrow your search. They’re all reliable and would make excellent choices for your organic search needs.
