What Is a Technical SEO Agency
A technical SEO agency optimizes a website's technical infrastructure, not its content or backlinks, so search engines can crawl, render, and index it correctly. That work typically covers site speed and Core Web Vitals, mobile-friendliness, HTTPS, XML sitemaps, robots.txt, structured data, JavaScript rendering, and site architecture. The standard engagement is a technical SEO audit: a review of crawl errors, site speed, mobile usability, sitemaps, robots.txt, structured data, and HTTPS status, followed by fixes to the issues it finds.
What Technical SEO Costs
Ongoing technical SEO retainers commonly start around $4,000 a month, with small business budgets running roughly $2,500 to $5,000, mid-market $5,000 to $10,000, and enterprise programs from $10,000 to $50,000 or more. A standalone technical SEO audit without an ongoing retainer typically costs $101 to $750 for a small site and $5,000 to $10,000 for a large or complex one. Audits are usually delivered in one to three weeks, and the ranking and traffic impact of the fixes they recommend tends to show up over the following two to four months or more as search engines re-crawl and re-index the site.

What is technical SEO?
Technical SEO is the practice of optimizing a website's technical infrastructure, not its content or backlinks, so search engines can crawl, render, and index it correctly. It covers areas like site speed, mobile-friendliness, HTTPS, XML sitemaps, robots.txt, structured data, JavaScript rendering, and site architecture.
What does a technical SEO agency actually do?
Most technical SEO agencies start with a technical SEO audit, a review of crawl errors, site speed, mobile usability, sitemaps, robots.txt, structured data, and HTTPS status. From there they fix the issues the audit surfaces and monitor re-crawling and re-indexing as search engines pick up the changes.
How much does a technical SEO agency cost?
Ongoing technical SEO retainers commonly start around $4,000 a month. Small business budgets tend to run $2,500 to $5,000 a month, mid-market $5,000 to $10,000, and enterprise programs $10,000 to $50,000 or more. A one-off technical SEO audit without a retainer runs $101 to $750 for a small site and $5,000 to $10,000 for a large or complex one.
How long does technical SEO take to show results?
A standalone technical audit is usually delivered in one to three weeks. The ranking and traffic impact of the fixes it recommends typically shows up over the following two to four months or more, as search engines re-crawl and re-index the affected pages.
How are the agencies on this page ordered?
Agencies are ordered by partner tier: Certified Partner first, then Partner, then Unverified. Tier reflects an agency's verification status with AIclicks, not a performance score or a ranking of quality. Unverified profiles were compiled from public search results and have not been claimed by the agency yet, so their details are deliberately minimal. Any agency can claim its profile to correct and expand it.
