What Is Crawling?

Crawling is the process by which search engines discover and fetch pages, following links from one URL to the next.

In plain English

A crawler starts from URLs it already knows, requests each page, reads the links on it, and adds anything new to a queue. That is the whole mechanism.

Everything else in SEO depends on this step. A page that is never crawled cannot be indexed, and a page that is not indexed cannot rank for anything.

What to know

Discovery
New URLs are found through links, sitemaps and previously known pages.
Fetching
The page is requested like a browser would request it, subject to robots rules.
Queueing
Links found on the page are added to the crawl queue for later.
Recrawling
Pages are revisited at intervals based on how often they appear to change.

Why it matters

Most serious SEO problems are crawling problems in disguise. Before asking why a page does not rank, the question is whether it was reached at all, and Search Console answers that directly.

Common mistakes

×Orphaned pages with no internal links, so nothing leads a crawler to them.
×Blocking resources in robots.txt that the page needs in order to render.
×Assuming a sitemap guarantees crawling. It suggests, it does not compel.
×Slow server responses, which reduce how much gets crawled.

FAQs

How do I get a page crawled faster?

Link to it internally from a page that is crawled often, and submit it in Search Console.

Does crawling mean indexing?

No. A page can be crawled and then not indexed, which Search Console reports separately.
