Hi All. I’ve seen in Google index links from sites that are actually search results for various searches visitors performed. For example if you search for Donations on Google you can see URLs addresses like: www.mywebsite.com/search.html?q=Donations HTML: For most web sites the only way to generate such a URL is if user goes to the search.html page and searches for 'Donations' This link doesn’t exists anywhere. It's dynamically generated using GET method when users performed searches. My question is how Google indexes those search result pages on its own index. One way I can think of is if these URL are listed in a sitemap, but I think Google will look for other pages linking to them as well. I'm talking for web sites that have for example 30 000 pages indexed by Google like www.mywebsite.com/search.html?q=Donations www.mywebsite.com/search.html?q=Tomato HTML: Most of them don't have even a search results it's just an empty page. The recent Crawling through HTML forms Google approach could be a reason too.
