15 days cycle of keywords??

Keywords of mine site do lists in top 5 in every 15 days, and after 15 days ranking reduced, and appears in next 15 days. I want to stick these keywords.
Is there any technical problem, or need some corrections.
Suggest me.

 

How old is your site? If new you will experience a boost then drop after few days/weeks.

 

strange having a 15 day cycle... google changes every day..

 

I think it's normal that google changes your site position, but 15 days cycle...

 

I've been seeing a similar cycle since the middle of Jan. Not exactly 15 days but a cycle none the less. Unfortunately I'm down more than up

 

There seems to be a Google dance that is happening more frequently. I've seen the same type of behavior for some of my sites. The results for the first 5 spots even on major keywords seems to be almost random. The same players are always there, but in different positions.

 

dont worry, if you read all the recent threads made in this catogory you will see that alot of people complain about this at the moment. i think its just one of those periods that come and go.

 

your keyword result is fluctuated so u need to solid backlinks for your website of high pr so it will stict

 

Try to get more and more relevant back link for your site to get the stable rankings.

 

How long have you see these cycles?
