What Each Ranking and Directory Answers — and When to Use Which
There are four entry points here that do not require you to know what you are looking for first: the advertiser ranking, the domain ranking, the multi-advertiser domain directory, and the advertiser directory. Each sorts by something different and answers a different question. Using the wrong one produces the classic mistake — reading google.com as a brand under siege. This post covers what each sorts by, what it is good for, and how to read its top of the list.
1. What each one is for
| Entry point | Sorted by | Answers | Who tops it |
|---|---|---|---|
| Rankings · who is advertising | Landing domains covered per advertiser | Whose delivery structure is most complex right now | Agencies, affiliates, directory businesses |
| Rankings · where ads land | Advertisers pointing at a domain | Where traffic is most concentrated | Platform domains (social, search, site builders) |
| Multi-advertiser domains | Same, but the full paginated set | Which domains are repeatedly targeted by many entities | Same as above |
| Advertiser directory | Associated landing domains | The full list of advertisers with enough data | Same as row one |
The first two are two tabs of one page and give you a head snapshot. The last two are full directories you can page through, each showing its current indexable total. For a quick read of the landscape use the rankings; for systematic work or finding a specific target use the directories.
2. Platform domains top the list, and that is correct
The domain side sorts by "how many distinct advertisers drive traffic here", so the top is permanently google.com, instagram.com, facebook.com, whatsapp.com, youtube.com. These are not brands under siege — an enormous number of advertisers simply land there: follow us, download the app, message us.
One tier down sits the site-builder and link-in-bio set: linktr.ee, canva.site, naver.com, squarespace.com. Same story — thousands of small advertisers use them as landing pages, so the advertiser count is naturally high.
Worth memorizing: platform domains carry high advertiser counts by nature; anomaly detection depends on the type of domain, not the absolute number. A company's own website appearing at that magnitude is the real signal.
Which means the actual use of this ranking is to scroll down. The top twenty carry almost no information. Somewhere in the middle, domains relevant to your category — ones you have never heard of — start to appear, and those are the ones worth opening to see who runs them.
3. On the advertiser side, domain coverage is the sort key
Both the advertiser ranking and the advertiser directory sort by associated landing domains, not by creative count. That is deliberate: creative count only says how much someone spends, while domain coverage says what role they play.
The top is consistently these types:
- Directory / local business aggregation: Yellow Book USA, Inc, 7,000+ landing domains.
- Cross-industry traffic distribution: BlueVision Interactive Limited 4,000+, Click Tech Limited 3,700+.
- Vertical media agencies: automotive dealer marketing is a large block — Dealer Spike, Dealer.com, Incorporated, DealerOn, Inc., each 1,600–1,700+ domains; Conversion Logix LLC is the equivalent in residential real estate.
- Vertical SaaS that also buys media: Luxury Presence, Inc., 2,800+.
The pattern is clear: almost no brands at the top — it is all intermediaries. An advertiser promoting its own brand may run enormous volume but only two or three landing domains (Booking.com and Tripadvisor are both on 2), so it can never rank on this key. To find a brand, search for it; do not look for it in a ranking.
4. Four readings that actually pay off
1. Find the agencies in your vertical. Page down the advertiser directory and open entities whose names carry industry signals. Check whether their frequent landing domains are your competitors. Once you know who your competitor outsourced media to, you have their playbook as a reusable template.
2. Find domains with only one advertiser. The rankings sort from high coverage down, but the valuable positions for an attacker are at the other end: a landing page already validated, with no second entrant. You will not find those in a ranking — you get there by following an advertiser's frequent domains backwards, as described in Mapping an Advertiser's Entire Landing-Page Network.
3. Defenders: use it as an anomaly sweep. Page the multi-advertiser domain directory weekly and look only for new faces in your category. Your own brand domain appearing there with a rising advertiser count is something to investigate immediately.
4. Use the "last active" column to discard history. Both the rankings and the directories carry it. An entity covering 2,000 domains whose last activity was months ago is far less informative than one covering 300 that is still running this week.
5. How much is visible
The rankings are tiered by role: guests see the top 20, trial members the top 50, full members the top 500; anonymous visitors see 6 rows above the fold, with the page stating how many follow. The two directories page through freely, but the rows are sampled the same way — the totals are real, the rows are a sample.
Free is enough to read the landscape and pick a direction; enumerating an entire tier systematically requires a subscription. Every visitor, search engine crawlers included, receives exactly the same page.
6. Rankings are discovery, not conclusions
One closing caution: all four entry points exist to narrow the field. No row in a ranking is a conclusion on its own — a high position means large numbers, not that it concerns you and not that it is profitable. When something looks relevant, open the detail page, classify it by landing-domain composition, check whether it is still running via run duration (see Using Run Duration to Tell Which Google Ads Are Actually Profitable), and only then decide it is worth your time.
FAQ
Why does the advertiser ranking sort by domains rather than creatives?
Creative count is dominated by asset rotation frequency — at equal budget, an account that refreshes weekly can show dozens of times more creatives. Domain coverage reflects delivery structure, which is the more useful sort key for discovery.
The top domains are google.com and facebook.com. Is the data broken?
No. The sort key is how many advertisers drive traffic to a domain, and a great many advertisers land on social platforms and site builders. Anomaly detection has to account for the type of domain.
How often do the rankings update?
Ranking data is recomputed weekly, and each page states its own data cutoff — the page is authoritative.
Why can't I find the brand I follow in the rankings?
Brands advertising themselves usually have only 2–3 landing domains, so they never rank on domain coverage. Use search or the advertiser directory by name.
What is the difference between a directory and a ranking?
A ranking is a head snapshot, tiered at the top 20 / 50 / 500 by role. A directory is the full paginated set, with the current indexable total shown on the page.
Landing-domain counts cited here are lower bounds on the current page values; the detail and directory pages are authoritative. Ranking and directory data cutoffs are shown on their own pages. Verified 2026-08-17.
