The risk section of the s1 is pretty large. At least for the SEO portion, I would guess the biggest risk is that google gets wise and figures out how to block search result scraping better. It is a constant battle to react to changes made to prevent scraping by coming up with new work arounds to get around those changes.

At what price would you buy it though? 1000 P/E? No thanks. Besides you need to account for all the risks.

Good news is that this company is aiming quite a lot lower than 1000!

What? They have no earnings (profits), the PE is infinity.
