About Rankupedia and how its entries are written
A reference, not a blog. Entries are short, dated and limited to what the link index can show.
What the site is
Rankupedia pairs a link-data API with a written reference. It is small by design. The API covers backlinks, referring domains, anchor text, top pages and a 0-100 Domain Rating, and each term has an entry.
The data comes from our own crawler and our own link index: 181,132,097 domains, 2,774,625,913 domain-to-domain links and about 798.5 billion backlinks. It refreshes roughly once a month. Nothing else is claimed.
Edits are by the Rankupedia editorial team. No named authors are invented. No customer stories appear.
Everything here is meant to be looked up, not read from top to bottom. Hence the short format: a definition, a number, a caveat.
What the reference covers
| Area | Entry | Covers |
|---|---|---|
| Metric | DR formula | Arithmetic and worked examples |
| Vocabulary | Glossary | Eleven terms from anchor text to SpamBrain |
| Integration | API fields | Parameters, ok and _credits |
| Money | Cost table | Credits per action |
| Diagnosis | Error codes | 401, 402 and empty results |
Editing rules
One term per entry
A reader should find the answer in the first two lines.
Sourced or marked
Statements about Google follow its Search Central documentation. Examples are labelled as examples.
Limits stated
Monthly refresh, own metric, no keyword data. Ahrefs and Semrush are fuller products for those.
Sign in and use the account page for questions about your key or balance.
What it is not
It is not a rank tracker and not a keyword tool. Ahrefs and Semrush are the fuller products for keywords, rank tracking and daily-fresh crawling, and we say so wherever the question arises.
It is also not a substitute for Google Search Console, which is the only source that shows the links Google itself reports for a verified site.
Who reads it
Three kinds of reader arrive, each with a narrow question.
The report recipient
A client sends a PDF from Ahrefs or Semrush and wants the abbreviations explained in a sentence each.
The integrator
A developer needs the parameter list and the price of a loop before writing code.
The sceptic
Someone doubts that a DR checker means anything to Google. The myth entry is for them.
Corrections
If an entry is wrong, say so. Use the account page. Entries carry an update date so a reader can tell whether a correction has landed.
Our one standing caveat is the data: a roughly monthly refresh means any figure is a snapshot, and a single domain-rating checker lookup should be quoted with its date.
How the lookup and the reference connect
The free domain rating checker on the home page is the front door. It returns DR and a referring-domain count, and every number it shows has an entry behind it.
That pairing is deliberate. A bare score invites misuse, so the explanation sits one click away. Anyone who wants the arithmetic can reproduce it in a minute.
The index behind it has grown to 181,132,097 domains and about 798.5 billion backlinks. Those totals describe our crawl. They do not describe the whole web, and no entry claims they do.
What each entry contains
- A definition in the first two lines
- One or more concrete numbers or dates
- A statement of what the thing does not measure
- Links to the neighbouring entries
- An update date
