I changed the on my site's title tags and page content. It probably take a long time (months) until Google has "reindexed" all pages with new title tags and content. I set crawl rate in webmaster tools 1000% faster. Did I make the right thing? If not, how to get that 5000 pages site to get reindexed faster?
Wait, google will crawl your pages soon. I set crawl rate in webmaster tools 1000% faster.(this doesn`t helps you a lot) Wait is the answer
In my own experiences, it would not work. Google crawler would crawl your sites basing the update frequency of your site contents. IMO.
