SEO Crawler is a software tool that systematically scans and analyzes a website’s structure, content, and technical aspects, much like how search engine bots (or crawlers) do.
The primary purpose of an SEO crawler is to identify issues that may affect a website’s performance in search engine rankings.
By mimicking the behavior of search engine crawlers, SEO crawlers help website owners and SEO professionals gain insights into how search engines view their site and what improvements are needed.
How SEO Crawlers Work
Crawling
An SEO crawler starts by visiting the URL you provide, typically the homepage of a website.
From there, it follows links on the page to discover other pages on the site, just like a search engine bot would.
The crawler continues this process until it has scanned all accessible pages on the website.
Analyzing
As the SEO crawler visits each page, it analyzes various elements such as meta tags, headings, content, images, internal links, and URLs.
It also checks for technical issues like broken links, duplicate content, and page load speed.
Reporting
After the crawling process is complete, the tool generates a detailed report that highlights the findings.
This report typically includes information about technical SEO issues, on-page SEO elements, content analysis, and recommendations for improvement.
