Hi ExtraWinner, thanks for the useful info... currently this issue is very, very actual. Will appreciate your thoughts.
I would refer my situation to (But not at least)...
A) Did you got some private blog network backlinks?
If you see a penalty some time after you got some private blog network post backlinks - even some long months later - it could meant that blog network got de-indexed (check your reports and forums for any comments about de-indexing networks).
Penalty recognition:
- sudden drop in rankings without any reason (sometimes it could be 3-5 spots, sometimes 100-200 spots)
I will start with a single example, because all my sites got hit. I was using almost the same backlink building strategy and all of them were added in the same Analytics / Webmaster accounts, so I just don't know why all of them are hit...
One of my sites was ranking on a lot keywords in auto insurance niche, 250+ pages of the highest quality content, each page was at least 700 words, time on site was more than 4 minutes, page/visit more than 3. People loved it...
As of backlink building, I was using article directories (Many of them) and blog networks heavily besides quality comments, web 2.0 link building, backlinking backlinks with xrumer, social bookmarks, authority websites, guest posts, high quality web directories...
On about 5th of Feb I lost #1-5 position rankings for ALL main keywords (including LSI). No longtails were hit AT ALL... 3-4 days after I totally lost all rankings including longtails. Instead of pages which were ranked on the keywords, I was seeing my other pages (which included the term) on #50-100 positions. The pages which were ranking on those keywords just disappeared from SERPs. Now I only rank on my exact domain keyword...
As of now, here is what I'm thinking about the reasons:
1. No brand linking (I should not have over used anchor texts, even click here is natural)
2. Over using spun content (as more as you use it, it gets less unique and easily trackable)
3. Over using blog networks... I checked about 50 of my 2-3 month old backlinks, all the homepage PR is 0, they lost it... some of them are deindexed.
4. In general, over using low quality link sources.
I feel i have a penalty because of all above. The links still stay the strongest indicator.
Do you think that getting medium / high quality backlinks will really help? Or I just should 301 websites to the new domains and move content?
Thanks in advance!
Regards,
Vaz
