I made a website in the dating marketplace one year ago. After hard work made 12 months i see results now. Today i searched for ranking in google for some powerfull keywords and the result was that i am no.45. Then i tryed to find it manually on Google but nothing. After this i tryed other tools and all of them are displaying same results. My question is why these tools are showing my position for some keywords but when i search manually i can't find it? May be this caused by the datacenters update?
I think that Google is not returning the same result for all data centres. So, for example, you might be number 45 on the Australian centre, (if there is one?), but you might be number 200 on one of the US ones. FFMG
One can check the different DataCenter results by going to http://www.webrankinfo.com/english/tools/google-data-centers.php all the best
