How this service works
Places an order to have a website submitted to twenty directories that publish a link back to it, and returns a confirmation number so the order can be checked later for free.
Output
A confirmation number (order ID) that can be used later to check the status of the directory submission order free of charge. The service queues the site URL for submission across twenty web directories that will publish a backlink pointing back to the submitted URL.
Example use cases
New blog launch link building
“I just launched my blog at https://technotestbed.io and want to kick off some backlink building — can you submit it to those 20 directories and get me a confirmation number?”
Local business directory push
“Submit https://brooklynplumbingpros.com to 20 directories to get some backlinks going for local SEO, and give me the order confirmation so I can follow up later.”
Client SEO campaign kickoff
“I'm starting an SEO campaign for a client — please submit https://greenleaflawfirm.com to 20 link directories and return the confirmation number so I can track it in my project notes.”
