Here’s a client where we built a moderate number of links over a 2 month period. Before this they had a fairly large backlink profile, but of mostly lower quality links. Only one of the links we then built was paid.
The rest were completely free, and built via manual outreach techniques. One link was built via HARO.
Client sold motorcycle accessories: https://americanlegendrider.com/
