Why does adlinkfly needs safelink?
Because the AdLinkFly communicates and redirects you to blog1 (safelink client, also a blog for a simple redirection) then blog1 will redirect you to blog2 (safelink server, wich is a blog with ads where you can either get paid for CPM Ads either for CPC if you decide to imlement a js and force the users to click on ads) and after the completion of the blog steps, you will get redirected to the shortner final page wich will redirect you to the shortened link.
You can also use safelink server to multiple blogs and do unlimited steps.
If you own a shortner with this method is because you will earn a lot of money.
I used this method in past with google adsense, adskeeper and mgid - Ad Networks, and i used it with forced click. The earnings are extremely high but you need to be smart and not just gain clicks on ads but dive traffic too because if you have a high CTR you will become suspect for those ad networks and get your account banned.
You must maintain the CTR under 4-5 always, so, if you decide to run a URL Shortner with this intention, spend some money on traffic.
To get publishers for your url shortner just create an faucetpay account, go to the faucets list and contact them with the porposal to add your url shortner to their faucet as the 90% of the crypto faucets have shortlinks modules.
Have fun and thanks for this version of wp-safelink, i will test it soon to see in there are major changes from the original one (i have the original licensed one too).
