I am hearinng from a LOT of people that they lost sites which got deindexed. This is NOT unique to BLOG NETWORKS.
The common factors are they have admitted their sites were WEAK or even BAD or had scraped content from ezinearticles on the home pages.
Same thing with my sites. Sites in the BU network and sites NOT in the BU NETWORK.
not ALL bu SITES WERE DEINDEXED. nOT ALL OF my SITES WERE DEINXED. oNLY THE WEAK ONES.
I see a LOT of my sites that were VALUABLE sites were not affected. They are still indexed.
Some of them are RANKING HIGHER. Some of them are RANKING HIGHER for VERY COMPETITIVE terms and YES I lost some links. BUT SO DID EVERYONE ELSE!
So even though I lost links from the BU blogs - some of my sites have gone up SIGNIFICANTLY even for very competitive keywords.
I've heard this from other people too.
I had sites deindexed that I can honestly say were WEAK. They were SHORT on offering value to the end user.
They were GOOD enough for me - I don't think they should have been banned - but obviuosly Google is making changes and they are FOCUSING ON QUALITY
They want quality - it's very clear this is what the big picture is.
ALL my sites that were STRONG GOOD SITES with quality are still in the index and still getting traffic.
I have friends and relatives who are NOT in any way connected to any blog network or even bad linking and they have told me their sites are NOT indexed by Google any more.
The deindexing of sites was NOT JUST BLOG NETWORKS period.
If you were NOT deindexed that is great - you might be fine.
BUT it is very clear that Google is making QUALITY ADJUSTMENTS.
Either you embrace what is happening and deal with it or you ignore it and try to blame other things.
In the long run we will ALL need to improve quality or risk getting deindexed.
For now it seems very clear to me that the best thing I can do and anyone can do that wants to protect their sites that are indexed by Google is to make sure that the HOME PAGE has real value for a visitor.
I don't have all the answers NOR does anyone else.
A lot of the stuff being said is pure speculation.
It is 100% clear that what they did was for IMPROVING QUALITY on Google searches.
LINKS coming in most likely will NOT cause problems for you so far as QUALITY is concerned.
You can't control who links to you.
You CAN control what is on your site. So if there is a possibility it is WEAK in value try to improve it.
I do understand that blog netowrks have been hit hard. Some more than others but this is far wider reaching than just BU.
If your site is still in the index you are lucky.
You should not be worrying. You should be focusing on delivering good content.
If you have sites deindexed that's certainly not good - but the're gone - don't spend time on those for now - instead of focusing on what you have that is NOT GOOD or LOST - try to focus your efforts on what you have that is good and make that work as best it can.
