What Is a Website Crawler?
A website crawler (also called a spider or bot) is a tool that systematically browses the internet by following links from page to page. Search engines like Google use crawlers to discover and index web content. SEO crawlers like SEOAudits do the same thing — but for analysis and optimization rather than indexing.
SEOAudits's crawler starts from your homepage and follows every internal link it finds, building a complete map of your site architecture. It records HTTP status codes, page titles, meta descriptions, headings, and content for every page it visits. This data feeds into our scoring engine to produce a comprehensive SEO audit.
Unlike simple page checkers, SEOAudits's crawler handles JavaScript-rendered content, respects robots.txt directives, and can detect issues that only appear when navigating between pages (like redirect chains and orphan pages).
Why Crawl Your Website Regularly?
- Find broken links — 404 errors hurt user experience and waste crawl budget
- Discover orphan pages — Unlinked pages are invisible to search engines
- Map redirects — Long redirect chains slow down crawlers and users
- Audit indexability — Check noindex tags and canonical URLs at scale
- Monitor site changes — Regular crawls catch issues introduced by updates
What SEOAudits's Crawler Finds
Deep Page Discovery
Crawl up to 2,000 pages per audit following every internal link. Discover pages you forgot existed, including orphaned content that search engines might miss.
Redirect Chain Detection
Identify redirect chains and loops that waste crawl budget and slow down user experience. SEOAudits maps every redirect hop and flags chains longer than 3 hops.
Broken Link Finder
Find 404 errors, 500 server errors, and other HTTP issues across your entire site. SEOAudits checks every internal and external link found during the crawl.
Crawl Budget Analysis
Understand how search engines spend their crawl budget on your site. SEOAudits identifies low-value pages, duplicate content, and parameters that waste crawler resources.
Orphan Page Detection
Find pages that exist on your server but are not linked from anywhere on your site. Orphan pages are invisible to search engine crawlers and represent missed ranking opportunities.
Sitemap & Robots.txt Analysis
SEOAudits automatically fetches and validates your sitemap.xml and robots.txt files. Check for disallowed important pages, missing sitemap entries, and malformed directives.

How the Crawl Works
Seed URL
You enter your homepage URL. SEOAudits validates the URL and queues it for crawling.
Discovery
The crawler fetches the page, parses HTML, and extracts all internal links. Each new link is added to the queue if it matches the same domain and has not been visited yet.
Recursive Crawl
The process repeats for every discovered page until all reachable pages are visited or the page limit is reached. The crawler respects robots.txt and avoids nofollow links.
Analysis
After crawling, SEOAudits runs the scoring engine on all collected data. It checks titles, meta descriptions, headings, images, performance, schema markup, and GEO signals.
Report
You receive a comprehensive audit report with a 0-100 score, prioritized issue list, per-page breakdowns, and actionable fix instructions.
