As stated here: blackhatworld.com/blackhat-seo/seo-link-building/467238-search-engine-optimization-shark-outrank-your-competitors-100-penguin-panda-safe-20.html They claim their SEO SERVICE is the best one there is, so far I beg to differ. Here is my review (Which can also be found at the topic of the above link) about their service. So far I'm very dissatisfied with SEO SHARK. In the beginning Cecilia was very helpful, but after I purchased the plan, I was just another customer. I'm not saying she didn't help me or anything, no, she does help you out, but I was left alone talking to myself in Skype many times, and mostly she takes too long to answer. I know you may have 1, 2, 10, 40 customers at once to offer support to, but that's not my problem, there were times when we were talking and suddenly I had to wait an average of 3 hours to get an answer. If you're offering support to someone, you just don't disappear. Also I feel like I've been fooled, none of their plans works as described, their excuse is that they have to change the way they execute their SEO campaign regularly, due do panda/penguin, ok, it's fine, I get it, but at least update the plans table on the website, I purchased the plan based on what I saw on your site, not on what you provide now. Last week I tried reaching Andrei at Skype, he never replied me. The only thing that keeps me up from putting a 2 stars review in this is the fact that I'm waiting for my campaign report, which, according to them, no one ever complained of the results, ok, I'm waiting. So here's what I think about this service so far: PROS - Most of the time Cecilia is very helpful. - She will help you on your onpage optimization. - She's very polite CONS - Support is really slow, and sometimes you'll be left alone without an answer. - Their plans table is outdated - Ask them everything you have to ask before you hire them, if you don't want to face any surprises, like I did - Andrei never replied me at Skype - In the plans table says the lemon plan takes 10 days for generating a report, after purchasing the plan I was informed that it takes 10 to 15 days. - They refused to tell me how many articles, backlinks, forum profiles, etc, I'm going to get, said that they have "their own way" of making things happens. Final considerations: Even though I may have hired the Lemon Plan for a test, which is the cheapest one, I expected to be treated with the same respect as someone that would for a Megalodon plan. If it doesn't meet my expectations, I'm not going to hire the Tiger plan as I intend to, and I'll make a very poor review here. I expected more from you guys.
