Headline numbers

Providers tracked

84

The number of provider guides published in the directory when this page was last built.

Dofollow share

45%

Share of providers whose recommended backlink method typically outputs a dofollow link, as documented on each provider page.

Free option share

96%

Share of providers where the recommended backlink path can be completed without paying the provider.

Free + dofollow

37

Providers that are both free and dofollow — the combination most link builders look for first.

Median authority

15/100

Median of the per-provider Domain Authority scores shown on provider pages. These score the actual backlink surface, not the provider homepage.

Median time

23m

Median of the per-provider time estimates: the minimum minutes a prepared user needs to sign up, set up, and place the backlink.

Median spam score

02

Median of the per-provider spam scores shown on provider pages, from researched values or conservative editorial estimates.

Median paid cost

$16

Median minimum cost among paid providers with a documented price. Prices change; each provider page carries the current researched figure.

Free versus paid

Free providers dominate the directory, and paying does not automatically buy a stronger link — compare the median authority scores before spending.

Methodology

Figures on this page are computed at build time from the provider directory — the same per-provider values shown on each guide, aggregated. Domain authority, spam score, and difficulty are editorial comparison estimates scored per backlink surface; time is the estimated minimum for a prepared user; costs are researched minimums that can change at any time. Medians are used instead of averages so a few outliers cannot distort the picture. Last computed on August 19, 2026.
