Every backlink tool is a snapshot of the web taken by someone else's crawler, on someone else's schedule. Understanding how that snapshot is built, updated and scored helps you decide what to trust and what to double-check. This page explains the general mechanics behind Backrefs link data and where the limits are. I don't have access to Backrefs' internal crawl rates, index size or scoring formulas, so for current specifics, confirm details on the official site at backrefs.com.
The Three Stages: Collect, Refresh, Score
Most link databases work in the same three stages, and it's useful to keep them separate in your head:
- Collection: a crawler discovers pages, reads the links on them and records the source page, target URL, anchor text and link attributes.
- Refresh: pages are revisited to see whether links still exist, changed or disappeared. This is what produces new and lost link reports.
- Scoring: metrics are calculated to help you prioritize. They are estimates, not facts about how a search engine sees a page.
For the product-level view of what Backrefs does with this data, see Features & How Backrefs Works.
How Link Data Is Collected
What gets recorded
Typically, each link record includes the linking page, the linked page, anchor text, and whether the link is followed, nofollow, sponsored or UGC. Check inside your account which fields are shown, since field availability can differ by plan or view.
What collection misses
- Pages the crawler never found. No index covers the whole web. A link can be real and live but absent from the data.
- Blocked or gated pages. Pages behind logins, robots restrictions or heavy JavaScript rendering are harder to read.
- Low-visibility pages. Crawlers prioritize what looks important, so obscure pages are found later or not at all.
Practical consequence: treat any backlink count as a floor, not a total. If a link you know exists is missing, that's normal, not a reason to distrust everything else.
How Refreshing Works (and Why It Lags)
A link is only marked lost when a crawler revisits the page and no longer finds it. Pages that are revisited often show changes quickly; deep or rarely updated pages can take much longer. That means:
- A "new" link may have been live for days or weeks before it appears.
- A "lost" link may be a crawl miss, a temporary error or a page that's been moved, not a true removal.
- Dates shown are usually when the tool saw the link, not when it was published.

A quick verification step for lost links
- Open the linking page in your browser.
- View the page source or search for your domain.
- Check whether the page redirects, returns an error, or the link changed URL.
- Only then decide whether to contact the site owner.

Authority-style scores are modeled approximations. They're built from the link data the tool holds, so they inherit its gaps. Search engines don't use them. Use them to sort, not to judge.
A sensible way to read a score
- Use scores to rank a long list, then review the top candidates by hand.
- Compare sites within the same niche; scores across unrelated topics mean little.
- Check relevance, traffic signs and editorial quality yourself. A mid-score relevant site can beat a high-score irrelevant one.
- Don't compare numbers between different tools; the scales aren't the same.
Tool Data vs. Your Own Checks
| Question | Rely on the tool for | Verify yourself |
|---|---|---|
| Who links to me? | A fast, broad list | Anything important or surprising |
| What changed? | Spotting movement | Whether a lost link is truly gone |
| Is a site worth pursuing? | Rough prioritization | Relevance, quality, audience |
| Competitor gaps | Finding candidates | Whether a link is realistically earnable |
Putting It Into a Workflow
- Set up your project and run your first report: How to Set Up Backrefs.
- Check changes weekly, not daily, since refresh lag makes daily checks noisy: A Weekly Backrefs Routine.
- Look for gaps against competitors: Finding Competitor Link Gaps in Backrefs.
- Export and share what you find: Reports and Exports.
Note that analysis and outreach are different jobs. See Does Backrefs include outreach or email tools? for what to expect, and Integrations, API, Alerts and Extension for what each plan includes.
Honest Trade-offs
- Coverage vs. cost: larger indexes usually cost more. Whether Backrefs' coverage suits you depends on your niche, so test it against links you already know about.
- Freshness vs. completeness: no tool maximizes both.
- Convenience vs. certainty: scores save time but hide uncertainty.
A useful trial: take ten links you know exist and check how many appear, and how quickly new ones show up. That tells you more than any marketing claim.

No link tool can promise rankings or results. It gives you evidence to make better decisions, and those decisions still need your judgment.
