I recently made a few changes to my website and have been waiting for them to be indexed by goolge. It seems to taking forever. The last cache date was 8/20/12 and that just happened to be the day that my site was down so the cached page is blank. (Does that have an effect on my rankings?) I have submitted the url to google a few time and nothing. Any suggestions?
It can take a couple of weeks for Google to fully index the change. It is likely that Googlebot has visited your page and observed the change, it just hasn't updated the cache yet. Just build some links to it and it will happen on its own in the near future
update the content if possible, this is the way to get cache more. Besides, try to get more quality backlink which will helps much as well
Also dont waste your time worrying about Google indexing you changes, it will happen in time on its own. Instead spend that time improving your link profile
Yes I agree with you sir. yes backlinks also are good when indexing your site but it would take days for your site to show up.. you must be patient.
