Six checks, in order, cheapest first. None of them needs a tool, an account or any technical knowledge. Run in sequence they take about ninety seconds, and most of the time you will have your answer after the first two.
Each check comes with the mechanism that produces the tell. That matters more than the tell itself, because pages are laid out differently and a memorised list of things to look for stops working as soon as a page is shaped unusually. If you know why the trace exists, you can find it anywhere.
What this is, and who it is for
This is a field procedure for anyone about to act on a listing page: contact a supplier, sign up for something, or hand over a phone number. It tells you what kind of page you are on. It does not tell you whether the businesses on it are any good.
Say the important thing once, up front. A paid listing is not evidence of a bad business. Advertising is a normal cost of trading, and a business that pays to appear somewhere its customers look is doing something entirely ordinary. Many listed businesses have no idea how the site orders its results, and some do not know they are on it at all. Everything below is aimed at the page. None of it is aimed at the companies on it.
The mechanisms behind these tells are set out in full in the five business models behind these tells.
When to use this (and when it is not worth the ninety seconds)
Run it when the decision is consequential or reversible only with effort: hiring a trade, choosing a supplier you will pay monthly, or anything that starts by giving out your phone number.
Do not bother when you are browsing, when you already know the business and only came for its address, or when you are going to visit the business's own site and decide there anyway. The check tells you how much weight the page can carry. If the page is carrying no weight in your decision, skip it.
Check 1: the disclosure, and where it is hiding
The mechanism. Publishers who take money for placement generally say so somewhere. Where they say it reflects how much they wanted it read.
What to do. Before reading any entry, scan for words like sponsored, featured, promoted, partner, advertising or commission. Check three places in this order: directly above or beside the first entry, in the site's footer, and inside any collapsed or "read more" block near the top.
How to read the result. A disclosure in plain words, in body-text size, above the content, means a publisher is telling you something in time for it to be useful. The same words in a footer link or in small grey type meet the letter of the thing while defeating the purpose. Note where you found it and carry on. Absence of any disclosure is not proof of anything either way, but it does mean the page has given you nothing to work with.
Check 2: the ordering, and whether it survives a filter change
The mechanism. If position is sold, position is fixed. It cannot respond to your query, because it was set by a rate card before you arrived.
What to do. Find any control that should change the order: a sort dropdown, a category filter, a location box, a price band. Change it. Watch the top three entries.
How to read the result. If the top entries stay put through changes that ought to reorder everything, something other than relevance is holding them there. That something is often paid position, and it is often labelled if you look closely at the first result's background colour or badge. If the order does respond sensibly, the ordering is at least a function of your input.
There is a variant worth knowing. Some pages sell only the first two or three slots and rank the rest by something else. So look specifically at where the visual treatment changes down the page. That boundary is frequently the boundary of the paid inventory. Anatomy of a top 10 list covers what an ordering means once any part of it is purchasable.
Check 3: the link — what happens between click and destination
The mechanism. Affiliate commissions and lead attribution both require the site to know that the click came from them. Knowing that requires the click to pass through something.
What to do. Hover over the main outbound link and read the destination in the bottom corner of your browser. On a phone, press and hold until the address appears. Do not click yet.
How to read the result. A plain address for the business's own site suggests nothing is being earned on the click. A redirect service, a tracking domain, or the business's address followed by a long string of parameters suggests a commercial relationship. A link that stays inside the listing site and never reaches the business at all usually means the site wants you to use its form instead, which is the lead-sale pattern.
None of this is hidden in a sinister sense. Tracking parameters are how affiliate accounting works. You are simply establishing which model funds the page.
Check 4: the profile depth gap between top and bottom entries
The mechanism. Paid tiers buy features as well as position: more photographs, a longer description, a logo, a clickable website field, opening hours. Free or scraped entries get the minimum.
What to do. Compare the first entry on the page with one near the bottom. Count what the top one has that the bottom one does not.
How to read the result. A large, consistent gap in richness usually maps onto a paid tier boundary rather than a difference between the businesses. The business at the bottom may be larger, older and better than the one at the top. It simply did not buy the package. This tell is useful precisely because it reveals the price list without you having to find the price list.
There is a related pattern in the other direction. If every entry is identically shallow, with the same fields filled to the same depth, the listings were probably imported in bulk rather than compiled one at a time, which raises a different question about whether anyone has checked them since.
Check 5: the "advertise with us" page and what it charges for
The mechanism. A site selling something to businesses has to describe what it sells. That description is written for buyers, not for you, so it is usually far more candid than anything on the reader-facing pages.
What to do. Look in the footer for a link aimed at businesses: advertise with us, list your business, for partners, pricing, or join. Open it and read what the tiers include.
How to read the result. This is the highest-yield check on the list. The tier names tell you whether inclusion is sold, whether position is sold, and whether leads are sold. Language like "guaranteed top placement", "featured in your category" or "exclusive enquiries in your area" answers in one line what the other five checks infer. If there is no such page at all, either the site does not sell to businesses or it sells privately.
Check 6: the date on the page versus the dates in the listings
The mechanism. A page-level date is trivially easy to refresh and a listing-level check date is expensive to produce. When the two disagree, the cheap one has usually been updated and the expensive one has not.
What to do. Find the date on the page: "updated" in a header, a year in a title, a copyright line. Then look for any date attached to an individual listing. Compare them.
How to read the result. A current page date with no dates on any individual entry means the page was touched, not that anything was checked. If listings carry no date at all, you have no way to know whether the business still trades, which is a separate and very common problem covered in why directories are full of businesses that closed years ago. A year in a title with nothing dated underneath it is a formatting convention, not a claim about currency. The same reasoning applies to badges, which is why what a verified badge would have to prove is mostly about dates.
What a clean result does and does not prove
Suppose all six checks come back clean. There is no paid-position tell, no advertise page, no redirect on the outbound links, an even depth across entries and dates on individual listings.
What that means: the page is probably not funded by placement, and someone has probably done some maintenance. It is reasonable to give the page more weight than you otherwise would.
What it does not mean:
- Not that the businesses are good. No check on this page is about the businesses. Quality is not visible from a listing page at all.
- Not that no money is involved. Arrangements can exist without leaving a trace on the page, and a clean-looking page can be funded in ways these checks do not reach.
- Not that the information is current. Dates prove a check happened, not that the check was thorough or that the business has not changed since.
- Not that the coverage is complete. A clean page can still omit most of a category, and absence from a list is not a signal about a business.
A clean result raises the ceiling on how much the page can be trusted. It does not do your thinking about the business itself. For that, the next step is reading the review section underneath, and then a direct look at the business's own site.
Finally, an obvious use for these checks: run them on us. Every one of the six applies here, and the answers are meant to be boring. Who pays for this site states the mechanism behind each of them.
In Plain English
What it means. Six quick observations tell you whether a listing page is funded by placement, by commission, by selling enquiries, or by none of those. They tell you nothing about the businesses listed.
Who it helps. Anyone about to contact a supplier or hand over contact details after finding them on a list.
When to use it. In the first ninety seconds on the page, before you read the entries and well before you fill in a form.
What to do next. Run checks one and two now, on whatever listing page brought you here. If the answer is uncomfortable, go to the business's own site and start again from there.
Keeping the six checks to hand
The six checks are complete on this page and nowhere else: no separate card, no email, nothing to download. The six headings above are the card — disclosure, ordering, link, profile depth, the advertise-with-us page, and the dates — and each one carries the mechanism that produces the tell, so you can rebuild the reasoning rather than memorise a list. Printing this page gives you the working copy. The rest of the free checklists are at templates, and the broader background is at how directories work.
