An old site has been indexed by Google already and for a long time (2 years+). But do not know recently why Google do not index "some pages" of the site for one day by checking many Google DCs but those pages just not listed by searching Google { site: URL }. (using URL means only some pages not the domain all sites de-indexed) After these pages re-indexed its cache time is showing several days ago. Do you have experience like this? How a page but not a site can be separated away from all DCs? Can any one explain? Regards,
mine dissapeared from google for like 4 days (homepage, it was ranked 1, i almost had a heart attack, it happens....
Google often uses other datacenters to suppliment the main index while adjusting their algo. This is probably what you are experiencing.
SERP's depends on the Data Center serving the search query at the time you hit the submit button.. However, Google DC's goes on/off all the time. and they might be using out-dated DC's at that time
Within 15 minutes ? That's nearly impossible. Not that I don't trust you ... but Google cannot index your post that fast, nor pushes it to all their DC in that amount of time. Unless it's big news that got on Google news.
lol 15 mins thats great if it was true. i thik data centrs are one reason, but also consider that google has recently chanded its algorthm a few days ago, and your site might be too seo optimized, google has pcked up on this and now gives low rank to high seo sites. i had to change many things on my sites since google changed its algo, i was doing quite well untill google algo change im still suffering i have not got over it. try to use less keywords on your pages. also no more than 1 h1 tag.
