Hello Friends i want to know about over optimisation because when google update over optimization penalty my sites ranking very down. so how can i recover my site.
The best thing would be creating fresh content for the pages and then working on them... Change your on page and create relevant and powerful back links.... I don't think you can reverse the over seo thing...but slowly your website will gain rankings. Do not do link building blind folded...Just the relevant website for that.... Good luck
