About alex krako

I am a self published writer that grew tired of expensive SEO online services.

I decided to create my own Kindle/Amazon SEO tool called Kindle Ranker( www.kindleranker.com).

You can use it to find the least competitive Kindle categories, estimate revenu of each sub category, check out the competition, find long tail keywords...for free.

unlimited access costs $2, which is still 15 to 100 times cheaper than the competition.
