What does the company do well? They know how to sell themselves to get your credit card.
What does the company not do well? I joined, paid $500, and after more than 2 weeks they finally emailed me the keywords they were going to rank my site for. It was obvious that their 'team' hadn't done even the most basic research of visiting my website - they simply went to the backend of my WordPress site. The keywords were not relevant to my site. The next day, after explaining why the keywords weren't relevant I was told I would have to wait until after I paid next month's fee of $400 to get them updated. In other words, after $900 they would use keywords that were relevant to my site. After I pushed back, they agreed to update the keywords - one week later they sent me the new keywords which, unbelievably, still weren't anything close to what my website is about. This is after I clearly explained in an email who my customer is - in one sentence of about 10 words. It seems that Boostability is really more of a front end sales organization designed to get your credit card and then hope you don't cancel.
What do you wish you had known about the company before using? That they are mainly a sales organization.
