HI guys, i have a site that was ranking very well for all keywords, then when penguin come in, i lost some rankings on some pages. It cant be due to bad links as I have never bought and links and have no dodgy links going to my site. After the update, I changed all the text on the pages and saw a slight increase in rankings. 1 month later, now when I search for paragraphs of text from the page, some times it does not even show in the serp results? Any ideas?
