  3. Did you know you can shorten your long links with AdFly and make dollars for every visit to your shortened urls.

  4. But you have a domain name and you've decided to repurpose that site for some of your offers or products. Use a URL shortener to help avoid turning people off just due to the domain name. This can help you keep moving forward until you are ready or able to buy another domain name that suits your marketing efforts better. url shortener

  5. General it seems, by all accounts, to be a legitimate procedure, however I can't shake the sentiment of strolling through a third world market endeavoring to fend off my wallet from some person's pet monkey. The yearly expense is ~$75/yr. url shortener

  6. Maybe their most serious issue is that is doesn't resemble a URL by any stretch of the imagination. link shortener

  7. A url shortener is a Website that will create a short Uniform Resource Locator (URL) or Web page address from a long one so that the short version, which is easier to remember and enter, can be used instead.
