Metrics & quality signals in UpSnatch
Last updated: February 2026
How to interpret the visible metrics in the Domains table and Domain Details.
Table of contents
Before you rely on any metric
Metrics and quality signals are indicators, not guarantees.
A domain can score well and still be risky (spam history, trademark issues, irrelevant backlinks)
A domain can have weak metrics and still be valuable (short, brandable names often have few/no backlinks)
Rule-of-thumb thresholds vary by niche, language, and TLD
Use metrics to shortlist.
Then verify candidates via the domain details and your own due diligence.
Spam & Safety
The Spam quality or Spam level helps you to scan results quickly. It gives an indication of how trustworthy a domain is, how trustworthy its backlink profile is, and whether it is known to have been abused.
Important
The spam level is a risk indicator, not a verdict. Always confirm with Wayback Machine to do deep history check and check with your favorite link analysis tool to assess the backlink profile, especially before spending on an auction.
Levels (worst → best)
| Level | What it means | How to use it |
|---|---|---|
| Spam | Strong spam/abuse warning. The domain is either explicitly flagged for spam-like behavior, or its backlink profile looks heavily “manufactured” (lots of low-value links, unnatural patterns, or obvious abuse history signals). | Usually filter out. Only consider if you have a clear reason (e.g. its a premium domain name or brandable that you will be able to restore). This domain has a high risk of algorithmic demotion and potential Manual actions in Google Search Console. |
| Suspicious | The domain has a noticeable backlink footprint, but very little of it looks trustworthy. In practice this often means lots of spammy links from low-quality or irrelevant sources, sitewide/footer links, or other patterns that inflate link counts without adding real credibility. | Be cautious. Review the domain details and check the Wayback Machine to see whether the domain has been abused. Use your favorite link analysis tool to assess the backlink profile. Check the search engine to see whether the domain is still indexed and if the content is relevant and natural. |
| Caution | Mixed signals. The backlink profile isn’t clearly spam, but it also isn’t clearly clean. It may include a blend of “okay” links and questionable ones, or it may simply lack enough strong sources to feel confident at a glance. | Interpret in context. Combine with other metrics and a history check before making a decision. |
| Okay | No detected heavy spam signals, or a very small link footprint. This usually means there’s no obvious spam signal, but also not enough link data to conclude the domain is “strong” from backlinks alone. | Absence of evidence is not evidence of absence. Don't assume "good", as it can also mean "no negative signal yet." Useful for filtering out obvious spam while keeping clean, low-data domains. |
| Good | The backlink profile looks generally healthy: links appear more credible overall, with fewer signs of inflated or low-quality link patterns. Not perfect proof, but typically a reassuring signal for link quality. | Generally a positive link-quality sign. Still verify relevance and history (e.g., topic shifts). |
| Best | Best you can get. The links that matter look very trustworthy compared to the overall link footprint, which often correlates with cleaner backlink history and more credible sources. | Strongest reassurance for link quality in this column. Still do Wayback checks and common-sense review. |
| Unclear | There is some data, but it’s too thin or inconsistent to classify confidently. This can happen when the domain has a tiny backlink footprint, or when the signals don’t point clearly in any one direction. | Treat as "can't tell." Use other columns and Domain Details for a manual review. |
| Unknown | Not enough data is available to generate a spam-quality label yet (for example, the domain hasn’t been enriched with link metrics, or link data is effectively missing). | Treat as "no data." Use other visible signals to assess the value and check the Wayback Machine and your favorite link analysis tool to assess the backlink profile. |
Remark that many default views have the spam level filter enabled by default. This is a good starting point to filter out obvious spam domains. However, if you are purely after name ideas, you can disable the filter in the Advanced Filter Settings and review the domains manually.
Other spam & safety signals
In addition to the Spam quality column, the following metrics are shown in the Domain Details:
| Metric | What it represents | How to use it |
|---|---|---|
| Affected by anti-spam algorithm | Whether the domain is flagged as affected by anti-spam/abuse (known to have been abused). | Treat as a strong warning, not an automatic disqualifier. Rule of thumb: if flagged, tighten your filters (higher TF, healthier TF/CF ratio) and always check Wayback and backlink tooling before bidding/buying. |
| Adult content | Whether the domain is marked as adult content. | Use to exclude domains for brand safety. Even if you're not in an adult niche, filtering this out reduces risk for clients and advertising platforms. |
These signals are heuristics and can have false positives and false negatives. A domain not flagged as spam (or not marked as adult) can still have a risky history, and occasionally a domain may be flagged even though it’s effectively clean. Use them as a quick filter, then confirm with due diligence (especially Wayback/history and backlink profile checks).
Valuation & Price
Useful for comparing opportunities, especially for investors, but always interpret as directional.
| Metric | What it represents | How to use it |
|---|---|---|
| Valuation | A third-party/provider appraisal estimate in USD. The source can differ per auction platform. | Use for sorting and rough comparisons, not as a target sale price. Rule of thumb: treat valuation as a "second opinion" and sanity-check against name quality and comparable sales in your niche. |
| Price | The current auction price / current bid (in USD), as reported by the auction platform. | Use it to stay within budget and compare value vs cost. Prices can change quickly and updates may not always be real-time. If you’re interested, click through to the auction site to confirm the latest price. |
Auction interest & Timing
These don't measure "quality" directly, but they help you prioritize what to review.
| Metric | What it represents | How to use it |
|---|---|---|
| Number of bids | How many bids have been placed in the auction. | A proxy for market interest. 0 bids can mean low interest, or simply that the auction is still early. Bid counts can change quickly and updates may not always be real-time, so click through to the auction site to confirm the latest status. |
| Auction end time | When the auction is scheduled to close. | Useful for prioritizing what to review first. Note: providers can sometimes remove or close an auction early (for example if the current owner renews the domain during the grace period), so always click through to the auction site to confirm the current status. |
Trust & Quality
Metrics that balance quality vs quantity of links and give an indication of how trustworthy a domain's backlink profile is.
| Metric | What it represents | How to use it |
|---|---|---|
| Trust Flow (TF) | A 0–100 score that estimates the quality and trust of a domain's inbound links. | Higher is generally better. Rule of thumb: TF ≥ 10 is often a reasonable starting point for SEO-focused filtering, but it varies a lot by niche and TLD. |
| Citation Flow (CF) | A 0–100 score that estimates the quantity/influence of a domain's inbound links. | Use with TF. A high CF with low TF can be a warning sign (lots of links, limited trust). |
| TF/CF ratio | Trust Flow divided by Citation Flow (a "trust per link" indicator). | Higher ratios are usually healthier. Rule of thumb: very low ratios can indicate an inflated link profile. Always double-check history and link context in due diligence. |
Remember: signals help you move faster, but the final decision should always include history checks, backlink profile checks, and common-sense review.
