I bought this just before New Year and OP was kind enough to give me the special discount he was running then. I promised to give a decent review here after I try it out so here it is:
First I've read about this software mostly at GSA forum and a few famous dudes there were saying they use it in combination with FCS with great success. Since I had FCS already working great, I decided to try it out.
At first glance I liked the software and thought it is worth paying the price for what it is supposed to do. I tried experimenting a bit, but quickly concluded that somethings not right. It wasn't creating accounts with pligg platform at all.. I messaged the support on skype and they quickly acknowledged the issue and fixed it in no time. Maybe because it was New Year they had a few bugs slipped away. I had some other small issues as well, but within only a few days(even during 31th Dec) the support was literally working for me and fixed every small little thing that was bothering me, even accepted a few new suggestions! Now the software is working perfectly well and I'm having great success with it. I must be honest and say that I was a bit disappointed when I saw the first few bugs just when I bought it, but now I'm very happy because it's working like a charm with the last update!
It's not only the software I'm happy about, but that I have invested into something with solid support behind it. As I've said a few times in this forum, I judge the software not by the cover, but by the support behind it and the developer's interest in accepting suggestions and molding the software to fit his clients needs. In the dynamic world of seo and www, things change so often and bugs in software like this are to be expected once in a while. The thing is about how quickly is it fixed and if the software upgrades, evolves and grows.
I was able to post with above 70% success rate on social bookmark sites, which is pretty high considering most of these are high PR sites. I have yet to see the result of this, but I'm confident that it will help me boost my Web 2.0 properties. I'm already seeing some rank improvement after a little more than a week since I posted a few campaigns to my sites. Account creation is a breeze, and I have really high rate on these as well like 90%. Nothing else currently is able to create and post to social bookmarks with this speed and success. It has content generation integrated and that's quick as well and the generated texts seems decent. It is great for T2 and T3 besides your GSA SER tiers. GSA SER supports social bookmarks as well, but no sites are integrated in it, you have to find them yourself(buying lists or scraping yourself which is a time consuming process) and the posting success rate probably won't be this high as well because this tool is specialized in this field and the developers test it all the time and are focused solely on increasing the success rate all the time and adding more high PR sites in there. I even use only a small portion of the highest PR sites to post tier 1s to my money site just to diversify my main backlink portfolio a bit.
There is only one thing I'd like to see done and that is their inbuilt sites. This is like a true gem of this software. There are 11 built in sites (like reddit, delicious) which use custom platform(and by the way it changes like every day) and each of them have to be specifically programmed in the software in order to automate the account creation and posting on them which is very hard to maintain, but the backlinks from them are totally worth it even as Tier 1. Currently only a few of them work, but the developer promised they would fix them all again in the upcoming week or two. The software is worth buying only for posting to these 11 sites alone if they were all working! And what about the rest of the 1600+, are you kidding me?! I truly hope they will fix them all because these 11 sites are the cream of the crop! Don't get me wrong, I don't expect all 11 to work all the time(that is just absurd, no one can do that) but I just hope they will maintain them and keep as many as possible of them working most of the time.
So my opinion is that this dev team here is on the right track with Ultimate Bookmarkr and I'd gladly buy their next product if I see it fit in my arsenal. Hope I can see you progress even more and release more SEO tools. Good job guys and keep it up!
