To make SEO work for your web applications you must understand how web crawlers operate. Google provides documentation that explains how its web crawler follows links, reads, understands and indexes content. Structuring your web applications to simplify the work for web crawlers achieves two desirable outcomes:
o Web crawlers will be able to read, understand and index the content.
o Web crawlers will finish the indexing job faster; website timeouts reduce the content available to web crawlers which can compromise the success of your SEO efforts.
Google is the most popular search engine; other general-purpose search engines include Bing and Yahoo! Search.
