I'm the co-founder of a fairly new startup that offers search engine ranking position tracker (SERP tracker) and domain statistics (Alexa, backlinks, PR etc.) at http://www.sescout.com.
We've decided to "do our part" to help fellow entrepreneurs out by offering unlimited free hourly keyword rank and domain statistics tracking to bootstrapped startups. The only stipulations are as follows:
You must have an "email(at)startup.com" address for verification
We won't put any limits on the amount of keywords you can track, however they must be relevant to your business (if your startup finds clown for children's birthday parties, you can't use the account to track "make money online kansas")
If you receive funding of any sort and continue to use our service, we expect out of goodwill that you would upgrade to a paid account ;]
While the terms SEO and startup don't usually coincide together, organic SEO traffic can be one of the cheapest and most effective ways for a budding startup to build up a core user-base. I have also noticed a recent influx of startup companies testing the waters of SEO in order to build up traction for their business.
That is all!
If you are interested and fit the criteria, please email us at "startup(at)sescout.com" and we'll set up an account for you.
P.S. if you are a funded startup and interested in giving us a test run, shoot as an email and we will look into it.
