A PROVEN WAY to get links is to have an article, relevant to some subject of your website, published with a link to your website.
There are websites which publish articles on a wide variety of subjects.
First search them for subject categories that are relevant to you.
Check the format accepted by each website.
Some ask for limited HTML – some ask for strictly plain text. If using a word processor paste your article into Notepad, and from there into the publishers form.
Use plain text format – no Microsoft Word formatting.
Compose your article, then submit it. Easy free submission – prompt acceptance from these publishers:
