Methodology
How our data is built
Link Pricing Index
The Link Pricing Index gathers published pricing data into one view. We do not run a survey of our own for it. The figures come from BuzzStream's analysis of more than 257,000 sites listed by link vendors, the Reporter Outreach survey of 500 SEO professionals, the Editorial.Link survey of 518, and an Ahrefs pricing test, and each one links to its study. When a study is rewritten with new data, as BuzzStream's two were in 2026, the index takes the new figures and drops the old ones.
Statistics hub
The statistics are gathered by topic, and each figure links to its primary source: the study, survey or dataset itself, never a round-up that quotes it. A figure is published only if we can read it in that source, in the same sense. The year shown is the date on the source page.
On October 17, 2026 we read every figure again. 28 were taken off the page: duplicates, figures we could only find in round-ups, figures from studies their authors have since rewritten, and one product description that was not a statistic. Several kept figures were corrected or re-sourced. The full list is in the corrections section of the statistics page.
Source links are also checked by a script (scripts/check-sources.mjs in the site code) that requests every cited page. When a source has gone offline, or now redirects to its site's home page, the statistic links to an Internet Archive copy of the page and says so.
Link Strength Score
The Link Strength Score is a deterministic model (not an opaque AI black box): it weighs the linking site's authority, topical relevance and anchor safety into a 0-100 score. The rubric is public and runs entirely in your browser.
