FAQ
What is an SEO crawler tool?
An SEO crawler tool is software that automatically scans a website's pages to find technical issues like broken links, missing metadata, duplicate content, and structural problems that can affect search engine crawling and indexing.
How does an SEO crawler differ from a web scraper?
An SEO crawler is designed to map site structure and analyze technical SEO elements, while a web scraper extracts specific content (like product prices) from pages. Crawlers mimic search engine bots; scrapers are for data extraction.
Is crawling the same as indexing?
No. Crawling is the discovery and fetching of pages by a bot. Indexing is the later step where search engines store and organize content for retrieval. A page can be crawled but not indexed.
What are common mistakes when using an SEO crawler?
Confusing crawling with indexing, only crawling the homepage, ignoring JavaScript-rendered content, and treating crawler findings as ranking guarantees instead of diagnostic signals.
