Vetting a publisher site before you buy a backlink means running four written checks, each ending in pass, hold or reject, before anyone reads the actual page. The checks cover indexing and server behaviour, the links surrounding yours, the site's history, and the seller's terms. One reject stops the order. The workflow is written for site owners, e-commerce teams and SEO agencies who buy links or sponsored articles and want a record they can defend later.
A site that passes the four checks has earned a page review, nothing more. Passing does not predict rankings, and the workflow makes no such promise. What it does is remove obvious problems cheaply, before time goes into judging a specific page.
What a pre-screen decides
Page reviews are slow. You read the article, check the anchor, look at the surrounding text and weigh the topic fit. A pre-screen is the fast filter that decides which sites deserve that effort. It looks at the domain-level behaviour that a good page cannot fix: a site Google cannot index, a site built around selling links, a site whose purpose changed overnight, or a seller who cannot be held to any terms.
Pre-screen versus page review
The pre-screen works on three objects. The site is the domain and its crawl, index and history behaviour. The page is the single URL where your link would sit. The seller is the person or intermediary quoting you, who may not own the site. The pre-screen covers the site and the seller. The page is judged afterwards, and reading the page instead of the site is a separate skill with its own checklist.
The three outcomes
Every check ends in one of three outcomes. Pass means no concern was found. Hold means something is unclear and the order waits for a written answer. Reject means a concrete problem was found and the order stops. Keeping a hold outcome matters because it stops two bad habits: rounding uncertainty up to a pass because the price looks good, and rounding it down to a reject without asking the seller anything.
Gate one: can the site be crawled and indexed?
The first gate is the cheapest and the one that answers the biggest question. If the pages where your link would live cannot be indexed, nothing else on this list matters.
What to open
Open an example post from the exact template your link would use. Ask the seller for a recent post in the same section if you do not already have one. Then look at three things. View the page source and search for a robots meta tag that includes noindex. Check the canonical link element and see whether it points to the same URL or somewhere else. Open the site's robots.txt file and see whether the section holding the posts is disallowed.
Google's robots meta tag documentation describes noindex as telling Google not to show the page in search results, and it describes the X-Robots-Tag as the way to deliver the same instruction in an HTTP response header. The same documentation says that when robots.txt blocks crawling, Google never sees the page's meta tags or headers, so any rules in them are ignored. The practical consequence for a buyer is that a blocked section cannot be rescued by a friendly meta tag.
Server behaviour
Load the post on different days and at different times of day. Google's documentation on HTTP status codes says that 5xx and 429 responses make its crawlers slow down temporarily, and that URLs which keep returning server errors are removed from the index. A single failure proves little. A site whose posts fail on repeated attempts is a poor home for a link you expect to stay visible.
Gate one outcomes
- Noindex or an equivalent header on the section where your link would sit: reject.
- Robots.txt blocking the section: reject, because the page rules cannot be seen.
- Canonical pointing to a different page: hold until the correct address is agreed in writing.
- Repeated server errors on different days: reject.
- All of the above clear on two separate days: pass.
Practical suggestion: make the second check on a different day from the first, and write both dates in the order record.
Gate two: who else is linked on the page?
The second gate looks at the company your link keeps. Google's spam policies (Opens in a new tab) define link spam as creating links to or from a site primarily to manipulate search rankings, and the examples include buying or selling links for ranking purposes, excessive link exchanges, partner pages created only for cross-linking, and paid articles or guest posts that pass ranking credit through optimized anchor text.
Paid links and rel values
Google states that paid links are acceptable when they are qualified with rel="nofollow" or rel="sponsored". The outbound links documentation (Opens in a new tab) prefers sponsored for advertisements and paid placements and calls nofollow an acceptable alternative. So a seller who offers to mark your link sponsored is following the documentation, not hiding something. The suspicious case is the opposite one: a paid article with keyword-heavy anchor text and no qualification, offered with the promise that it will lift your rankings. Documentation can change, so read the current pages before relying on the details above.
Link clusters on the same page
Count the other commercial links around yours and look at how they sit. Google's link best practices say the words before and after a link matter, advise against chaining links up next to each other, and note that spacing links out with text gives each one more context. A paragraph with four unrelated commercial links in a row reads like a link block, not like an editorial mention. For the wider framework of safe link acquisition, see Google link spam policies and safe link building.
Gate two outcomes
- A cluster of unrelated commercial links with keyword anchors on the page: reject.
- Paid links across the site without any qualification and no willingness to add it: reject, or hold while you request the change in writing.
- Your link inside a topical paragraph, separated from other links by text: pass.
Search Console also lists "Unnatural links from your site" as its own manual action type, so outbound linking behaviour is something Google reviews. If your interface is in another language, the report names may look different.
Gate three: where has the site been?
The third gate reads the site's timeline. Google's spam policies define expired domain abuse as buying an expired domain and repurposing it primarily to manipulate search rankings by hosting content with little value to users, and the example given is casino content on a former elementary school site. A publisher whose history shows a break like that is a poor candidate even if its current pages look tidy.
Topic breaks
Sort the site's posts by date and read the titles from oldest to newest. A school bulletin that becomes a casino review site, an author list that changes completely, or a language switch with no explanation are all signals. None is proof, because organizations do change direction, which is why the outcome is hold, not reject. Ask the seller to explain the site's ownership and topic history in writing.
Publishing bursts
A burst of near-identical posts in a short window resembles the scaled content abuse described in the spam policies, which covers many pages generated mainly to manipulate rankings instead of helping users. Read the first paragraph of several recent posts. If they share one template and say little, record that as a concern.
What a clean history looks like
A consistent subject, stable authors, dated posts that can be read start to finish and an about page that matches the content. A clean history does not guarantee anything, but it lets the site through this gate.
Gate four: the seller and the terms
The fourth gate asks who is on the other side. Buying from an intermediary is not wrong in itself, yet an intermediary who cannot reach the real site operator cannot fix problems after delivery.
Terms to obtain in writing
Get the page type, the link attribute (sponsored, nofollow or unqualified), the publication window, the correction and removal terms, and a statement of who owns the site. A quote that promises rankings conflicts with Google's guidance on third-party SEO services, which says no tool or service can guarantee rankings. The article on red-flag phrases in seller quotes helps with reading the wording.
Gate four outcomes
- Seller names the owner or operator and states correction terms: pass.
- Quote consists of a price and a ranking promise: reject.
- Seller will not answer ownership questions: hold, then reject if the silence continues.
Where the screen runs out
The pre-screen relies on what you can see from outside. You cannot see the site's internal operations, its other customers or its revenue model. Manual action status appears in the Manual actions report in Search Console, and a buyer has no access to that report for a site they do not manage. Asking the seller to state in writing whether the site has a known manual action is a reasonable extra step, though a statement is not proof.
The pre-screen also does not monitor a purchased link after publication. Plan a follow-up check on whether the link is still present, still carries the agreed attribute and whether the page remains indexable. The date of that follow-up belongs in the order record from day one. A link that disappears, changes its attribute or sits on a page that later gains noindex changes the value of the purchase, so the follow-up is part of the vetting process and not an optional extra.
The four gates in one table
| Gate | What you inspect | Reject signal | Evidence to keep |
|---|---|---|---|
| Indexing and server | Template, robots.txt, status codes | Noindex, blocked section, repeated server errors | Dates of two checks, page source note |
| Surrounding links | Links around yours | Unrelated commercial cluster, unqualified paid links | Dated screenshot |
| History | Old posts, topic line | Sudden topic switch, template bursts | List of old post dates |
| Seller and terms | Quote and ownership | Ranking promise, no operator access | Written quote and replies |
Decision rule: gate logic, not a score
Should the pre-screen use a numeric threshold or a pass, hold, reject logic? Practical suggestion: use gates. A score lets strong results in one area hide a serious defect in another, so a site with a pleasant history but a noindexed blog would still add up to a decent total. With gates, one critical reject stops the order, and hold keeps uncertain cases from being treated as either safe or unsafe.
The rule in five lines
- Reject at gate one or two stops the order.
- Hold at gate three needs a written explanation from the seller before the order continues.
- Reject at gate four means do not buy through this seller; ask whether the site owner can be reached directly.
- Two holds on the same site are treated as a reject unless both are resolved in writing.
- Only after four passes does the page review begin.
Slips that sink a pre-screen, at a glance
| Mistake | What goes wrong and what to do |
|---|---|
| Trusting a single metric | A third-party score cannot replace the four gates. Google states that third-party tools have no access to its internal ranking data. Record the score as a note and keep it out of the decision logic. |
| Checking only the home page | The home page can be clean while the section for posts follows different rules. Run every check on the template your link will use. |
| Accepting verbal assurances | A spoken promise leaves no evidence. Ask for the attribute, the correction terms and the ownership answer in writing. |
| Softening a reject later | Turning a reject into a hold because the price is attractive defeats the purpose. A reject changes only when its cause is removed, and the change is written down. |
Example scenario: an agency buying for a B2B software client
Example scenario: An agency is asked to place a sponsored article for a project-management software client. The first candidate is a business blog whose posts show a robots meta tag without noindex and clean status codes on two different days, so gate one passes. Gate two shows that the article would sit among two other commercial links in one sentence, both with exact-match anchors, and the seller says the paid links carry no qualification. The agency holds, asks in writing for sponsored qualification and for the other links to be separated, and the seller declines. The agency records a reject for gate two and moves on.
The second candidate passes gate one and gate two, but its oldest posts are about a local football club and the recent ones are about software tools, with a different author list. The agency holds at gate three and asks for the ownership history. The seller replies that the site was acquired and rebranded. The agency records the answer, treats the topic switch as unresolved, and declines to proceed until a former-owner statement is available. In both cases the value of the process lies in the record, because the client can see why each site was refused.
Doing the checks by hand
A browser and the documentation are enough for the core of this workflow. Paid tools may add information, yet Google's guidance on third-party SEO services says such tools have no access to Google's internal ranking data, so treat their scores as supporting notes, not as a replacement for the gates.
Which pages to sample
Pick at least three posts from the same template: a recent one, an old one and one in between. If all three show the same robots directives, link layout and status behaviour, the template is consistent. If one differs, ask why.
Status codes and redirect hops by hand
Browser developer tools show the status code of a URL and any redirect. Google's documentation describes 301 and 308 as permanent redirect signals and 302, 303 and 307 as temporary ones. If the address you were given redirects permanently somewhere else, ask the seller to place the link at the final address so the real URL is clear.
Questions to put to the seller
Some facts only the seller can supply. Ask before ordering and keep the answers.
Who owns and runs the site
- Are you the site operator, or an intermediary?
- Since when has the current owner used this domain?
- Is the site part of a network run by the same people?
What goes on the page
- Which attribute will the paid link carry?
- Who writes and approves the article, and how are corrections handled?
- Will other commercial links appear in the same article?
If the page is edited or taken down
- What happens if the link is removed or the URL changes?
- Do the terms continue if the site is sold?
Missing answers are themselves information. Record "seller did not answer" as a different fact from "seller refused", because the second is a firmer basis for rejecting.
When the gates disagree
Not every check ends cleanly. A page may load fine on Monday and fail on Wednesday. Of the surrounding links, one may be relevant and the next not.
When two checks disagree
If results differ across days, record the worse result and ask the seller to explain it. Because persistent server errors lead to removal from the index, a repeating error should not be treated as a one-off. If the error does not repeat on the next two checks, you may note the first result and pass.
Neighbours that half fit
When some of the links around yours are relevant and sit inside editorial text, a single unrelated link need not trigger a reject. Look at the pattern, not the count: do the unrelated links share the same anchor style, paragraph and commercial wording? If so, hold. Scattered links that fit the flow of the article raise no concern.
Gaps in the evidence
A seller who does not answer ownership or correction questions leaves the order on hold. The documentation defines no waiting period, so your team picks a sensible one and writes it into the record.
The order record
Keep one note for each purchase. A short record is enough, and it should answer the questions a colleague or client will ask later.
- Which site and which target URL did we check?
- On which dates were the indexing and server checks done?
- What did the surrounding links look like, and where is the screenshot?
- What did the history show, and who explained any topic change?
- Which link attribute did the seller commit to?
- Who approved the order and on what date?
Frequently Asked Questions
What is the difference between a pre-screen and a page review?
A pre-screen judges the site and the seller with pass, hold and reject outcomes. A page review reads the single URL where the link would sit. The pre-screen comes first, and only sites that pass it get a page review.
Is it a problem if a seller marks the paid link as sponsored?
No. Google's spam policies say paid links are acceptable when qualified with rel="nofollow" or rel="sponsored", and the outbound links documentation names sponsored as the preferred value for paid placements.
Should the pre-screen use a score or a pass-or-reject rule?
As a practical suggestion, use gates. A score can let good results in one area hide a serious defect in another. Adding a hold outcome covers cases that are unclear.
How many times should I run the indexing and server checks?
The documentation gives no number. As a practical suggestion, run them on at least two different days and write down the dates, since a single server error may be temporary.
What should I do if the seller promises rankings?
Treat it as a red flag. Google's guidance on third-party SEO services says no tool or service can guarantee rankings. Do not turn a quote with a ranking guarantee into an order.
Where do I check a site's history?
Reading the site's own older posts in date order is a sound start. Look for topic breaks and changes of author or language. If you find a break, ask the seller for a written account of ownership and topic history.
Conclusion
Publisher site vetting is a four-gate workflow with three outcomes: indexing and server behaviour, surrounding links, history, and seller terms, each ending in pass, hold or reject. A reject stops the order, a hold waits for a written answer, and only sites that pass all four gates move on to a page review. The workflow guarantees no ranking result, but it filters out sites that obviously carry risk and leaves a record for every purchase. Before ordering, write down the target URL, the link attribute and the check dates, and repeat the indexing and server check on a second day.
