What a technical SEO agency actually does
A technical SEO agency works on the parts of SEO that affect how search engines access, interpret, and rank a website. That includes crawlability, indexation, internal linking, site structure, Core Web Vitals, structured data, redirects, canonical handling, and sometimes JavaScript SEO or migration support.

How to evaluate a technical SEO agency
The right technical SEO agency should do three things well:
- Diagnose issues accurately: The agency should be able to identify technical problems clearly.
- Communicate clearly: They should explain complex issues in a way that’s easy for non-specialists to understand.
- Implement solutions effectively: The agency should help your team prioritize and fix problems in the right order to drive impact.
When comparing agencies, ask these key questions:
- Can they explain technical issues in plain language?
- Can they prioritize fixes based on business impact?
- Can they collaborate effectively with your developers?
- Do they have experience with sites like yours?
- Do reviews and case studies show actual results, not just talk?
Focusing on these factors ensures you select an agency that will not only diagnose issues but also help your team take action that improves your site’s search performance.
