I only worked with SEONitro and SEOLinkmonster for a short while, but the effects were enormous, BUT in the wrong direction...
Within 10 days I received dreaded - unnatural linking to my sites messages from WMT, I have been reading all day on this and other forums and sites and this is what I figured out what might be happening.
On SEONitro I checked over 450 domains my sites were placed on and it turned out ALL of the domains had been deindexed! All of them, I kid you not! Ofcourse seonitro support tells me that this happens all the time to SOME sites, and they will be replaced and then things will be better.
BUT it was not some sites; ALL the sites I checked were deindexed. Why the heck would they place customers links on deindexed sites?!
Then on SEOLinkmonster the first couple of days you could still check the domains that the articles had been placed on and again, ALL of them had been deindexed. Later I could not check anymore, that option had disappeared in their backend.
As soon as I saw that the articles were place on all deindexed sites I took my articles out of rotation, but this morning I found out that the damage already had been done. WMT already saw these sites as well and raised the flag.
So I spent a couple of hours to reverse lookup the articles that are mentioned in WMT - and when I check all sites linking to my sites I run into the sites I recognize with articles that come through SEOlinkmonster and lo and behold, ALL of them were deindexed sites.
After all my reading on this and other forums I now conclude that the main thing that triggered WMT unnatural linking warning must be the linking from deindexed domains.
So I have one thing to ask Dori Friend: please be nice to your customers and take down all deindexed sites, that would at least solve one problem for all of your customers who have been placed on deindexed domains, in that it would rid our sites of these apparently dangerous backlinks. And could you please do that for SEONitro AND SEOLinkmonster?
I am trying to get someone's attention as well on the SEONitro and SEOLinkmonster support sites as well, but apparently they are flooded with support tickets...
DORI, PLEASE take those deindexed sites down, because like I said, I fear that your blognetworks have been tracked down and the best thing you can now do with these sites for your customers is take them OUT and all links DOWN. That could perhaps limit the damage a bit.
I am now at the stage where I would gladly pay you to take those sites down so I get all links from deindexed sites pointing to my sites out of the way again, can you believe this?!
Dori, these deindexed sites will do you no good and I think they are detrimental to all people who have articles on them because - afaik - links from deindexed sites in networks raise huge red flags. Talk about footprint..
Apart from that I would have to say these guys know how to sell, because did they not convince me to jump on board? And the feeding of the articles went relatively smooth as well, so the back end really works as well.
Just one minor detail, they placed all my articles on deindexed sites.
What more can I say, probably this is lousy for your business as well.
Dori, please take the deindexed sites down?
