Shorte.st Review - Convert your Links to Money
Shorte.st is a link shortner service which allows users to shorten links as well as earn money by sharing your short links. As compared to Adfly, LinkShrink and other Link Shorter Shorte.st is more trustworthy with good features and proper payments. Shorte.st Review - How Shorte.st is better than other services? Shorte.st monetizes 5 views per IP in 24 hours. But I don't think it affects your earnings as nobody visits same link again and again within 24 hours. While many other link shortner services does not monetize first 3 views from every IP address. This affects you income to great extent. How to use Shorte.st? Almost anyone can use Shorte.st, specially the bloggers. Small bloggers cannot earn enough money from there websites, due to low traffic and approval rejection by Ad Networks which are traffic hungry. Shorte.st is best option for small bloggers. They can monetize each and every link on their website and also use website scripts of shorte.st to ...
