There are a few main benefits of niche edits:
We have relationships with editors on the site who will go in and edit an existing article for us. We have an inventory of over 20,000 websites which we can place links on, with a variety of different metrics and niches. We split all our niche edits down by Ahrefs domain rating metric.
The articles are already indexed and therefore we see ranking improvements quicker.
The articles will often already have T2 backlinks pointing at them, this is one of the main advantages over guest posts. As while a guest post might have good domain authority a new post won’t have good URL authority.
With our clients we are generally seeing a better ROI from niche edits. They work out cheaper than guest posts as we don’t have content costs.
Often the sites they are placed on don’t accept guest posts so some argue they are safer than guest posts.
