Speed For Adding Backlinks
This all depends on your current situation.
You can’t add lots of links all at once. We have to drip feed the backlinks as if the sites that will link to you find you over a period of time and link to you as a reference to supplement their own content.
Too many links created in a short period of time looks unnatural and can trigger a Google penalty.
A brand new site with no backlinks at all needs to be particularly careful to build their link profile gradually. Once you have more links and are attracting organic traffic, it is only natural for more sites to find you and to link to you so you can gradually increase the amount of backlinks we create.
We will advise you if you are unsure about how many backlinks are suitable to add to your site and a schedule for doing so.
