Why nobody links to your site
You publish regularly, the content is decent, and no one has ever linked to any of it.
A link is something the linker does for their own reader
Nobody links to be generous. They link because pointing at your page makes their own page better. If your page does not make someone else's argument stronger, save them time, or show them something they cannot get elsewhere, there is no reason for it to exist in their draft.
The three things that reliably attract links
A working tool that needs no account. Original data nobody else has. A reference page that settles a recurring argument. Notice that none of these is a blog post about your product.
Promotable is not linkable
A launch gets attention for a week. A tool gets linked for years. Optimising for the first at the expense of the second is the most common misallocation in early-stage marketing.
Nobody links to a page that sells
Read your top pages as a stranger. If every one ends in a call to action, there is nothing to cite: linking to it would be recommending a purchase, which people do rarely and reluctantly. The pages that earn links give something away completely, with no gate and no account. That is not generosity, it is the price of the link.
Make one thing worth citing
One tool, one dataset, one number nobody else has published. This site's entire link profile, 122 sites and roughly ~1,300 backlinks, traces back to a small number of pages that were useful on their own. You do not need a link building programme. You need one artefact that is easier to link to than to reproduce.
Measured, not asserted
Two links from fifty personalised outreach emails. Meanwhile the free tools on this project accumulated links passively, from people who needed to point someone at a thing that worked.
Free tool for this: Internal Link Graph. No account, nothing uploaded.
Where this goes deeper
Every number on this page comes from one complete dataset: one product taken from zero to 100K+ users on search alone, with nothing spent on advertising. The full argument is Chapter 24 of the book. Five chapters are free to read.
