What Are the 58 Signals We Measure?
The 58 signals are the full catalog of what Rank DNA reads on a page — the ruler, not your score. They are the same 58 signals for every site, in nine categories, and DNA Match counts only the ones where the winners in your market genuinely separate from the rest.
The Nine Signal Categories
Each category is its own page — crawlable, citable definitions in words you can act on, with no fix instruction and no data source named.
The crawl-and-render basics an engine needs to read the page cleanly.
How fast and stable the page feels to a real visitor.
The on-page building blocks a ranking page tends to have.
How much real, on-topic content the page carries.
How clearly the page is organised for readers and crawlers.
How the page connects to the rest of the site and the wider web.
The machine-readable data that tells engines what the page is.
The proof signals that show a business is real and credible.
The location signals that tie the page to a place and its customers.
The Questions People Ask
How many signals does Rank DNA measure?
Rank DNA reads 58 on-page signals, grouped into nine categories — technical, performance, on-page, content, structure, links, structured data, trust, and local.
Do all 58 signals count toward my score?
No. DNA Match counts only the signals where the pages ranking above you genuinely separate from the pages below you. The 58 are the ruler; the separating set is what is scored.
The Rank Codex reads this same catalog at depth — the ruler held steady while the market moves.
