I think I'm a victim of over optimisation on a lot of my sites since May 2014. Now I've learnt a lot about the subject but I'm just wondering if people could help create a reference on how to avoid it please with the latest Google algorithm ? I'll start with what I think is true (please correct me if I'm wrong) 1. Don't have any keyword density of something your trying to rank for above 3.5% 2. Only include your target keyword/keyphrase once in the main body text, then use different variations and orders to pad it out. 3. Don't use an exact anchor text of the keyword your trying to rank for for inbound links. Or if you do use it rarely. That's pretty much what I think triggers it so far. I could be wrong (probably am) so please let's put a good guide together that we can all use. What do you guys and girls think? How else would you stay safe? What kind of things are you ok doing?
