Google Can Crawl Over 100 Links Per Page
What most of us have always thought, Google and other search engines cannot crawl over 100 links on a single document, is now possible for them. The fact is that, the search engines can crawl more than 100 links on a web-page.
However, the Official Webmaster Guidelines page says, a document should not include more than 100 links, as well as many navigational options in order to keep it user- friendly.
“Offer a site map to your users with links that point to the important parts of your site. If the site map is larger than 100 or so links, you may want to break the site map into separate pages.”
“Keep the links on a given page to a reasonable number (fewer than 100).”- Google Guidelines
Here is what Googler, JohnMu had said in a Google Groups threads,
“Just for the record, we can process more than 100 links per page :-). We do however recommend the limit of 100 because it generally makes sense for users (and search engines).”
