Here is my boostability experience. I own a political website that features impartial summaries of political views and scandals.
Before hiring them, I spoke with a rep at length. I was clear as to what I expected. I wanted someone to look at my site, look at my competitors, and then tell me what I was doing wrong and assist me in developing organic traffic. That service simply was not performed. Furthermore, the service that they did provide was of extremely poor quality.
After hiring boostability, I sent an email with the same information I gave to the rep I spoke with before hiring the company - a list of my competitors and a list of possible keywords. A few days later, I received an email with "on-site recommendations". These recommendations consisted of changing an image tag and adding an h1 to my home page that contained the phrase "political representatives updates online." Although this phrase made no sense to me, as it seemed to have never been googled before, I made the changes and called the rep to ask questions. I was never able to get ahold of him.
No long after that, boostability created 6 articles that highlight this phrase and link it to my home page. The meaningless of this phrase can be seen by doing a simple google search for "political representative updates online" and seeing that the very articles they wrote appear on the first page results for that phrase.
I contacted their management and asked how these keywords could possibly help my website achieve traffic. They agreed that this was poor work and told me that future work would not only be better, but that the past work would be made up for in some manner since it would obviously present no benefit to my website and was not something I agreed to ahead of time.
I expected that there would be some research done on my site with some suggestion for on-site optimization, some suggestions for keywords to target, and some plan for the future of my site. I sent emails, as I had done in the past, with lists of my competitors and other things.
After receiving more emails simply asking me what keywords I wanted to target, I gave up on convincing them that this was the very reason I hired their company and suggested going after the phrases "political positions" and "election calendar." I sent them an email denoting which pages to attach those phrases. Boostability then posted three articles linking the phrase "election calendar" to my site and one linking the phrase "political positions".
One of these articles proclaimed the benefits of purchasing an election calendar. I know that google has no idea what the article is actually about and doesn't care that I don't sell election calendars, or even that such items do not exist. However, the article demonstrates a level of competence far below adequate. This is further exemplified by the fact that the article is not linked to the page I asked it to be linked to in my email. A second article, also highlighting the phrase "election calendar, " also links to my home page and not my election calendar page.
This means that after paying several hundred dollars, I received 10 articles links. All of the sites containing those articles have almost no domain authority or page rank. The sites seem to exist only to provide boostability customers with links. Six of those articles link the main page page of my site to the phrase "political representative updates online, " something that can only be detrimental to my site in the long run. Two articles link my home page to the phrase "election calendar, " one links the election calendar page to the phrase "election calendar, " and a final one links the phrase "political positions" to my home page.
That makes two articles which have any possibility of providing a benefit for my site for the keywords that I chose.
The only SEO that Boostability seems to be capable of doing is taking whatever phrase that you give to them, and then churning out meaningless articles linking that phrase to your site. They couldn't even perform this task correctly.
In addition, this practice of using low quality sites solely to anchor keywords to domains is frowned upon by google and was smashed by Panda and other updates. If these articles have any affect on your rankings, which is doubtful, it will be negative.
What Boostability attempted to do to me was not new. They target an unused phrase and then get your site on that first page of results for a phrase that is never searched. In this manner, they can make the claim that "they got you to the first page." However, this is meaningless if the phrase you rank highly for has never once been googled.
Stay away from this company.
