Maile Ohye has posted about the importance of link architecture over at Google blog. The second part of the link series discuss, the method of internal linking, which’s crucial step in site design if you want your site indexed by search engines and Googlebot.
- Although you may believe that users prefer a search box on your site rather than category navigation, it's uncommon for search engine crawlers to type into search boxes or navigate via pulldown menus. So make sure your important pages are clickable from the homepage and easyily crawlable for search engines and Googlebot.
- Intuitive navigation for users: Often breadcrumbs such as "Home > Techniques > Dribbling" help users to understand where they are.
- Crawlable links for search engines: keep-in-mind that when text-based links are available and easily navigable for users, chances are that search engines can crawl your site as well.
This <a href="new-page.html">text link</a> is easy for search engines to find.
- Sitemap submission is also helpful for major search engines, though it shouldn't be a substitute for crawlable link architecture. If your site utilizes newer techniques, such as AJAX, see "Verify that Googlebot finds your internal links" below.
- Use descriptive anchor text to help search engines and users to better understand your content like: Feel free to browse all of our <a href="videos.html">basketball videos</a>.
- Verify that Googlebot finds your internal links from Webmaster Tools “Links > Pages with internal links” and make sure that Googlebot is finding other internal links as expected.
