Audit your blog in minutes with top free blogger checker tools. Discover technical SEO auditors, broken link scanners, and AdSense checkers tailored for Blogger sites.
A Blogger template can carry missing JSON-LD schema, broken links, and outdated technical SEO tags while the site still looks fine to a reader. Parameter-based canonical URLs can also split similar mobile and desktop views into competing index entries.
That costs you the chance to earn clean indexing and rich-result eligibility. A dedicated Blogger audit checks the template XML, rendered page structure, links, and canonical signals before those faults keep spreading through new posts.
Start with a free checker that reads both the source template and the live URL. You get a clear repair list, then confirm the fix in Google Rich Results Test and Google Search Console.
Each checker covers a different part of a Blogger audit.
This walkthrough covers the main steps of a site audit.
Use one checker for the fault you need to find, then verify the repaired page rather than stopping at the first report.
Start with the part of the blog that has the clearest risk: template code, page health, ads readiness, links, content, or a full crawl. Blogger Template SEO Auditor and BlogVitals cover the first two paths directly.
Blogger Template SEO Auditor v5.0 PRO is for bloggers editing a custom theme or checking an older default template. It reads raw XML template architecture and the rendered DOM in the browser.
Choose it before pasting XML changes into Theme Editor. Its local browser execution also keeps the code in your browser during the audit.
BlogVitals is for a quick read on overall blog health when you want SEO, readability, links, and trust signals checked together. Its report runs more than 50 real-time checks in seconds.
Choose BlogVitals when the question is broad: what is wrong with the live blog right now? It gives a wider first-pass report than an XML-focused check.
AdSense Sandbox Checker is for bloggers reviewing a site's AdSense readiness. It scans direct AdSense scripts, WHOIS, and Google Cache indexation.
Choose it when ad readiness is the immediate concern. Its checks focus on signals tied to AdSense scripts and indexation.
BLaaG for Blogger is for a Blogger site with old posts, changed URLs, or outbound references that need checking. It is an online broken-link scanner built for Blogspot sites.
Choose BLaaG for Blogger when links are the job. Run it again after repairs to confirm that every 404 link is resolved or redirected.
SEOMatch is for bloggers checking article-level content and SEO. Its free tier includes 10 free articles per week and 20 articles per month.
Choose SEOMatch when your template is sound and individual posts need content review. For broader on-page work, these blogger SEO optimization tips can help shape the next edit.
Ahrefs Site Audit is for bloggers who need a crawl across many pages rather than a one-page check. Its free tier scans more than 170 SEO issues across up to 5,000 pages per month.
Choose Ahrefs when a blog has enough published pages that isolated checks miss recurring faults. A crawl can surface the same broken-link or canonical pattern across the site.
Ahrefs is the strongest pick for a site-wide crawl, while the Blogger Template SEO Auditor is the direct pick for XML and rendered-page checks. Use SEOMatch's pricing page to confirm its article allowance before making it part of a regular writing routine.

SE Ranking starts at $65 per month, which puts it in a paid category rather than this free-first list. Pick the narrow checker when you have one clear fault, then use Ahrefs for repeated issues spread across many pages.
Four steps are enough for a first pass. Keep a copy of the current template before changing any XML.
Kitful
Theme and then Edit HTML. Copy the XML you plan to inspect so the live template remains available for comparison.A blogger changes a canonical tag in the theme, then checks only the saved XML. The live URL can still render a different result, so the second check is the one that tells them whether Google can see the repair.
Quick rule: Verify every repair on the live URL before you move to the next issue.
A blogger checker is a web-based diagnostic service that evaluates a blog's technical health, SEO, template code, broken links, and AdSense readiness. Dedicated Blogger checks matter because a Blogspot site uses XML template code that controls what the live page renders.
A local browser audit keeps the template code in the browser while the audit runs. One auditor describes its process this way: "Your code is 100% private and secure. The auditing engine executes locally inside your web browser."
Still, keep a saved copy of the template before editing it. That gives you a clean version to restore if a pasted change causes a rendering problem.
Run an audit after you change a theme, add schema, alter canonical or robots settings, or repair a group of links. Regular checks also help catch new broken links and confirm that the live page still passes mobile and rich-results tests.
A checker can flag JSON-LD schema issues in the template or rendered page. Confirm the live URL with Google's Rich Results Test, because validation needs to happen on the page Google can fetch.
Start with the check that matches the problem: XML for template edits, a link scanner for 404s, a content checker for posts, or a crawl for site-wide faults.
Today, export your Blogger template, audit the live URL, fix one named issue, and verify the repair with Google Rich Results Test or Search Console.
