Hello everyone, I've been having this problem for quite a long time now(many months). I have several websites. They all were built to rank within a niche. Target keywords are/were (updates have passed, so things changed) easy. Yet, over the course of time, I have not seen any stable positioning within the top 100 for any of my keywords. The websites vary in content, some thin, others at least 10k words of content. Content is decent, not the best, but definitely well readable and 100% unique with images and videos included in most, if not all. SEO is not overoptimized and keyword density for all is max 2%, most of the time less. The sites are not dancing a lot... sometimes they're around 160/200, sometimes 240/270... Sometimes n/a. The weird thing is, within bing/yahoo I got some top10 positions for the same keywords. Ive tried several strategies to get solid rankings again, like social signals, high PR links, the lot... nothing seems to change though. Which one of you experts is tough enough to help out a fellow blackhatter? Thanks for reading!
