A Google ads library you can filter by network, country and format

A Google ads library lets you look up the ads a brand runs on Google and see where they run and for how long. In SellWinners you search Google ads by the words in the ad or by brand, then filter them by network, country, format and days running.

Search our Google ads library by keyword or brand

Type words from the ads to search a niche, or pick one brand to see the Google ads it runs. You can also leave the search empty and browse with filters only, which is the way to sort the results.

In Explore:

1. Open Explore, go to Ads and pick the Google tab.
2. Type words from the ad, or set Brand to one shop.
3. Set Status to active to keep the ads that are still running: those Google showed in the last 7 days. Without a status, an ad Google has not shown for more than a week says when it was last seen. Inactive keeps the ads marked as stopped, so those not seen for more than a week are under neither status.
4. Open Advanced filters. Under Audience, pick a network and the countries you sell in.
5. Under Running, set a minimum number of days running.
6. Clear the search text if you want to sort by newest or reach. There is no longest running sort: the day count it would rank by goes on after an ad stops, so it would list ads Google stopped showing long ago.

Filter Google ads by network, country and format

Google searches take 41 named filters. Explore groups them like this:

• Basic: status, and the Brand box for one shop.
• Audience: networks, formats, countries, audience countries to include or leave out, and a switch for EU and UK ads only.
• Running: days running, and a range of publish dates.
• Reach: a minimum and a maximum reach. Google reports a reach for some of the ads shown in the EU only, so a minimum keeps those.
• Shop: the category of the brand, the monthly visits of its site and its 30-day traffic growth.

Networks

The network filter takes Search, YouTube, Shopping and Maps. Each ad also tells you its network. Keep one network at a time, or compare how one brand uses each of them. For the video ads brands run on YouTube, see the YouTube ad spy tool.

Formats

Google ads come in three formats: text, image and video. The API's formats filter takes the same three names, upper or lower case. A video ad shows its thumbnail, with a Watch on Google link to the ad on Google's Ads Transparency Center, where the video plays. SellWinners does not host or play the video files.

Sort Google ads by newest or reach

A search text always ranks results by relevance. To sort, browse without one and narrow the list with filters instead. This call lists the Shopping ads Google still shows, the newest first:

# Search Google ads
curl "https://api.sellwinners.com/v1/google-ads?networks=shopping&status=active&sortBy=newest&limit=10" \
  -H "Authorization: Bearer YOUR_API_KEY"

GET /v1/google-ads Parameters and fields in the docs

Long-running ads are a good place to start, because the brand chose to keep paying for them. There is no longest running sort, so keep them with minDaysRunning, for example 30. Most ads that ran that long have stopped, so a broad list can end before its page is full, with meta.partial and a warning; one brand or a narrower search reads further.

What each Google ad shows

The ad

Its image, or the thumbnail of a video ad, its format (text, image or video), its status, the network it runs on, the dates it was first and last seen, and its days running.

The link to Google

The ad's page on Google's Ads Transparency Center, as transparencyUrl in the API. In Explore, a video ad links to it as Watch on Google.

The audience

Its countries, and whether it uses remarketing or interest targeting.

The reach

Google reports a reach for some of the ads shown in the EU, often only as 10M+ (the top of its scale), and most ads have none. Google ads have no spend figure.

The brand

The advertiser's name and domain, the monthly visits and traffic growth of its site, and, when known, how many active Meta and TikTok ads the same brand runs.

The brand line is where you go next. When a brand also runs Meta ads, the Meta ads library search shows them with reach for ads shown in the EU and the UK, and estimated spend. To see which brands advertise the most in your market first, find the top advertisers in a niche.

Google ads library API and MCP tool

This is the SellWinners API, not an official Google API. A POST takes the named filters at the top level of the body:

# Search Google ads with filters
curl -X POST "https://api.sellwinners.com/v1/google-ads/query" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "running shoes", "status": "active", "countries": ["DE", "FR"], "limit": 20}'

POST /v1/google-ads/query Parameters and fields in the docs

List the network values with GET /v1/google-ads/facets/networks, and read every parameter in the Google ads search reference. Your AI agent gets the same search through search_google_ads_library. You can ask it, for example, for active Google ads about running shoes on the Shopping network.

Google ads sit next to Meta and TikTok in the same ad spy tool. Google ads are on paid plans, with up to 5,000 results per search: see the plans and their prices.
