Most businesses only consider technical SEO agencies when they face significant issues — like a sudden drop in rankings, an increase in search console errors, or underperforming pages — that they can’t explain or resolve on their own.

When the work becomes too much for one person to handle or the problem feels beyond your expertise, the only real solution is finding the right partner.

What Should a Technical SEO Firm Provide?

A reputable technical SEO agency should go beyond surface-level, one-size-fits-all solutions. At a minimum, they should offer a comprehensive technical SEO audit service to identify problems like crawl errors, duplicate content, broken links, slow site speed, and other technical issues that can affect your discoverability.

A high-quality technical SEO service typically offers solutions like:

  • Site architecture analysis to ensure your website is easy to navigate
  • Indexing and crawlability improvements through regular updates to your XML sitemap and robots.txt
  • Link management to find and fix broken links
  • Core Web Vitals improvements for an improved user experience
  • Mobile optimization for a mobile-friendly website
  • Continuous monitoring and reporting to keep your website ranking

Ultimately, a trusted technical SEO partner will tailor their services to your business needs to help you meet your goals.

How Do You Choose the Best Technical SEO Agency?

When selecting the best technical SEO agency, it’s essential to evaluate a few key factors that directly impact your SEO strategy’s success.

First, look at the agency’s specialty services. While technical SEO is an ancillary offer from many, few understand how to balance and prioritize important SEO updates.

Next, examine the focus industries on their website to make sure you’re a good fit for their services. A strong portfolio of successful technical SEO case studies is a fantastic indicator of capability.

Additionally, assess customer reviews (i.e., Clutch) to understand the agency’s impact on past clients and their ability to adapt to different challenges.

Finally, schedule demos to get an idea of each company’s approach. Bring a list of questions to ask SEO agencies to ensure you’ll invest in the most valuable services.
