Pages missing from Google, redirect chains, duplicate URLs. Your [SEO agent](/agents/seo) checks every page every day and prepares the fix for each issue. --- ## What is technical SEO? Technical SEO is everything that [lets search engines crawl, index and understand your pages](/features/seo-geo): canonical tags, noindex rules, the sitemap, redirects, error pages and the heading structure of every web page. It is invisible to visitors, which is exactly why it breaks without anyone noticing. A technical SEO audit finds these indexing issues once. The SEO agent goes further: it runs a website health check on every page, every day, then fixes what it finds. acme.com | Issue | Pages | Clicks at risk | | --- | --- | --- | | Live pages set to noindexFix ready | 2 | 1,150 / mo | | Redirect chainsFix ready | 12 | 420 / mo | | Wrong canonicals | 0 | 0 | --- ## Why technical SEO comes first. Technical SEO is the base of any website optimization: content and links only bring organic traffic if Google can crawl, index and understand your pages. A single wrong tag can hide a page from search entirely, and small errors pile up as the site grows: every redesign, migration or batch of new blog posts adds redirects, duplicate URLs and headings that drift. Most sites carry these problems for months, simply because nobody runs the audit again. - 50% of websites have duplicate content issues. - 35% of websites have broken internal links. - 20% of websites use multiple H1 tags on a page. [Source: Semrush, study of 100,000 websites and 450 million pages (2016)](https://www.semrush.com/blog/semrush-study-on-site-seo-issues/) --- ## How it works. Every day, four steps. You only do the last one. 1. ### Crawls every page The SEO agent crawls your whole site the way Google does, and reads the indexing report in Google Search Console to see what Google sees. 2. ### Checks the essentials Canonical tags, noindex rules, the sitemap, status codes, redirects and headings, page by page, against the rules search engines follow. 3. ### Prepares every fix For each issue it writes the fix: a corrected tag, a redirect, a cleaned sitemap, a single H1. Nothing is left as a to-do list. 4. ### You approve, or it publishes The fixes wait in a preview with a short report: publish them, edit them, or turn them down. Or switch the routine to automatic and the SEO agent publishes them itself. Every version of the site is kept. --- ## Before and after. One blog post, three hidden problems, and what changes once the SEO agent fixes them. The fixes are highlighted. /guides/rewax-a-jacket - **Canonical tag: which page Google ranks**: Before:Google finds two copies of the guide and has to guess which one to show - After:Google shows the right page, and only that one - **Redirect: visitors from an old link**: Before:Bounced through two redirects before the page loads - After:Land straight on the guide - **H1: the main title of the page**: Before:Two main titles, the logo and the article title, so the topic is unclear - After: One main title that says what the guide is about --- ## What you get. - ### Every page findable The pages you want in Google are indexed, and the ones you do not want there stay out. - ### A cleaner Search Console Fewer crawl errors and excluded pages, week after week, instead of a report that keeps growing. - ### Fixes, not a to-do list Every issue comes with its fix already written, so nothing waits for a developer’s free afternoon. --- ## What it checks. The checks of a full technical SEO audit, run on every page, every day. - ### Indexing Like a canonical checker, a noindex checker and a robots tags checker in one: every page points to the right canonical URL, and no page you want in Google carries a noindex tag left over from a draft. - ### Sitemap Like a sitemap checker that never stops: the XML sitemap lists every page that should be indexed, and none that redirect, return an error or are set to noindex. - ### Crawl errors and 404s Pages that return errors, internal links that lead to them, and the crawl errors Google reports in Search Console, each with a redirect or a corrected link. - ### Redirects and URLs When you change a page’s address in Fimo, the redirect from the old one is created automatically. Like a redirect chain checker, the SEO agent handles the rest: chains collapsed into a single hop, loops broken, and one trailing slash rule across the site. - ### Headings Like an h1 checker: every page has one clear H1 that says what it is about, and the H2s and H3s below it follow a logical order, which keeps long pages user friendly. - ### Status codes The status code each page returns in its HTTP header: temporary redirects that should be permanent 301 redirects, soft 404s that look fine to visitors but confuse Google, and server errors that block crawling. --- ## Works with your tools. Search Console is all it needs to start. Connect Semrush or Ahrefs and the SEO agent reads their site audits too. - ![](https://increasing-magenta-albatross-5c363716c5.fimo.site/uploads/2026/10/14/RjAOwoMo-search.google.com.png) Search Console - ![](https://increasing-magenta-albatross-5c363716c5.fimo.site/uploads/2026/10/14/QMzXTo9x-semrush.com.png) SEMrush - ![](https://increasing-magenta-albatross-5c363716c5.fimo.site/uploads/2026/10/14/vg6ALI2--ahrefs.com.png) Ahrefs --- ## Works well with.

Straight answers. ### How do I fix 404 errors for SEO? A 404 is not a penalty in itself: Google expects some pages to disappear. The problem is a 404 on a specific page that still has links, traffic or rankings. For 404 errors, SEO best practice is simple: add a 301 redirect to the closest live page, remove it from the sitemap, and update the internal links that point to it. The SEO agent does all three, and leaves alone the 404s that do no harm. ### What is a redirect chain? A redirect chain is a URL that redirects to another URL, which redirects again before reaching the final page. Each hop slows the page down and can dilute the link equity passed by the links pointing to it. A redirect chain checker follows every hop; the SEO agent follows them too, then replaces the chain with a single 301 redirect to the final page. ### Does a trailing slash matter for SEO? Yes, when both versions work. For Google, /pricing and /pricing/ are two different URLs, so a site that answers on both has duplicate pages. Trailing slash SEO comes down to one rule: pick one form, redirect the other to it, and use it everywhere, in links, canonicals and the sitemap. The SEO agent applies that rule to every page. ### Are multiple H1 tags bad for SEO? Not for rankings: John Mueller, who answers SEO questions on behalf of Google Search, has said Google’s systems do not have a problem with multiple H1 headings on a page. But multiple H1 tags often come from a template mistake, like a logo marked up as a heading, and one clear H1 still helps readers, screen readers and AI assistants understand what the page is about. The SEO agent keeps one per page. [Source: Search Engine Land, “Multiple H1s won’t get in the way of your SEO, Google says” (2019)](https://searchengineland.com/multiple-h1s-wont-get-in-the-way-of-your-seo-google-says-322909) ### Does it fix everything it finds? Yes. Canonicals, noindex rules, the sitemap, redirects, 404 errors, status codes and headings: the SEO agent prepares each fix in a preview, and you publish, edit or turn it down. ### How is this different from SEO monitoring? Both are routines of the SEO agent. Technical SEO audits the site and fixes what is broken. [SEO monitoring](/agents/seo-monitoring) watches your rankings, clicks and every publish, and tells you when something changes. Monitoring often spots a problem first, and technical SEO fixes it. ### Do I need a developer? No. Fimo hosts your site, so the SEO agent fixes tags, redirects and the sitemap where they live, and the changes go live on their own or after your approval in a preview. Developers can still review the changes if your team prefers, since every fix is a regular change to the site. ### Which plan includes it?
