hi i got a website www.willowstairlifts.co.uk and I am doing seo for keyword Stairlifts , it was going all good i managed to get it from page 15 to page 4 but yesterday its start going backward it jumps back from position 31 to 61 ,

i have been very careful in doing on page and also with my link building. I have just a few directories , bookmarks and I am targeting guest post, and i have got few links from them.

i cant find anything wrong and worried, as surely it can be a penalty,

is it just google dance? as i am aware google is recently doing some updates which they are denying it.

hope you guys can help me ,

many thanks

/my domain is new as compare to the competitor , i hardly did any link building , my focus were to get link from guest post, so far i manage to get few but not to many,  few of the links are from yell and few relevant and popular uk directory which the client has setup himself and some bookmarks ,

There are no links so it can be spam.  also no errors in crawl could not find anything else suspicious.

the only thing i did was setup author profile with google + so that the image appear, on guest post and our blog post,

could that be an issue, as i see when i see the home page it comes with the author image.

Ok, first off this could very well be Google playing headgames. An article came out a while back that detailed a process Google was using to find people spamming the SERPs. Basically it worked like this: If they suspect you they'll drop you in rank, and see what you do. If you go around disavowing links, and doing reinclusion requests your pretty much indicating your spamming. So as long as your tactics are above board don't do anything crazy. Now, this could very well be part of a large update. Have your competitors shifted? Are there any indicators in the crawl report (i.e. lots of pages not selected, or a recent crawl abnormally large or small)? Let me know, and that should help narrow down the cause.
