Don't worry about it, just update your on-page work like Meta Title, Meta Description & Meta Keywords and then content of the page, to make all relative. I'm sure after IInd cache you will get your improved ranking or get back the same.
everyone's rankings are down. so google is choosing relevant search results ... keep fresh and relevant content and Concentrate On Traffic. I hope ranking will come back soon.
I bet your site is newer and you are a noob when it comes to SEO Tell us more or give us a domain name laterz malcolm
My site has come and gone from the rankings too, but now it has been about a month which has freaked me out so I went and changed my keywords and description for the site - was this a good or bad idea?
