What Every Value of Google's udm Search Parameter Does

All udm values at a glance

Every value of the udm search parameter that does something, plus what happens with the rest. Screenshots of each live result type follow below.

How we tested

On November 9-10, 2026 we loaded https://www.google.com/search?q=coffee&udm=N&hl=en&gl=us for every N from 0 to 70, plus the named values Google uses in its own tab links. For each page we recorded the highlighted tab, the final URL (to catch redirects) and what the results area contained, and took a screenshot.

"coffee" returns results in most types. Places, Jobs and Things to do came back empty for it, so we re-ran those with a query that fits (for example "barista jobs in austin" for Jobs), and used a real question for AI Mode. Values we mark as dead returned no results for every query we tried.

The 14 values that work

Each value that opens a working result type, with a screenshot of what Google returned.

udm=1: Places

A list of businesses with rating, price level, address and a review snippet, next to a map. It is the local results view without the rest of the page.

udm=2: Images

The image grid, the same page you get from the Images tab.

udm=3: Products

Product cards with price, discount, seller and rating, inside the normal Google page (search bar, tabs and filters).

udm=6: Learn

An expanded AI Overview followed by web results. It appears as a "Learn" tab on informational queries.

udm=7 (or udm=vids): Videos

Video results with thumbnail, duration, channel and date. Google's own Videos tab now links to udm=vids; udm=7 loads the same page.

udm=8: Jobs

Google's jobs panel: postings with employer, location, source site, posting age and pay, with filters for remote work, job type and date posted.

udm=12: News

Google redirects udm=12 to the older tbm=nws URL, so you land on the standard News results.

udm=14 (or udm=web): Web

Only the blue links: no AI Overview and no image, video or shopping blocks. This is the value people use to get "classic" Google. Google's own Web tab links to udm=web.

udm=15: Things to do

Attractions with rating, opening status and ticket price. It needs a place in the query.

udm=18 (or udm=forums): Forums

Discussion threads from Facebook groups, Reddit and dedicated forum sites, with comment counts, post age and a top answer.

udm=28: Shopping

The full Google Shopping page, with its own "Google Shopping" header, Search / Nearby / Deals tabs and a sort control. Compare udm=3, which shows products inside the normal search page.

udm=36 (or udm=books): Books

Google Books results with author, year and Read / More editions buttons.

udm=39 (or udm=short_vids): Short videos

A grid of vertical videos from YouTube, Facebook, TikTok and Instagram.

udm=50: AI Mode

Google's conversational AI search: a written answer with inline citations and a source panel on the right. A one-word query like "coffee" makes AI Mode ask what you mean, so we used a question.

Google now uses names for some values

Google's own tab links now use names instead of numbers for four result types:

udm=books also works, even though the Books tab still links to udm=36. Images (2), Shopping (28) and AI Mode (50) still use numbers. Names that look obvious but do nothing: udm=videos, udm=images and udm=shopping all fall back to the All page.

If you build Google URLs in code, the numbers are the safer choice today: every name above has a working number, but not every number has a name.

44 and 48 only work with Google Lens

udm=44 (Visual matches) and udm=48 (Exact matches) are the result tabs of Google Lens. They only have results when the search starts from an image. With a text query, the tab is highlighted but the page says there are no matches. To get Lens results as data, see the Real-Time Lens Data API.

Values that do nothing, or something odd

• udm=37 and udm=38 highlight a "Products" or "Videos" tab but returned no results for any query we tried. Use 3 and 7 instead.
• udm=51 highlights a "Homework" tab, but the results are identical to the All page.
• udm=49 redirects to the Google Images homepage (/imghp) and drops your query.
• udm=24 and udm=26 return Google's "400. That's an error" page.
• Every other value from 1 to 70, and udm=0, has no visible effect: you get the normal All page.

How udm relates to tbm

tbm is the older parameter for the same job (tbm=isch for images, tbm=nws for news). News is the one type where Google still prefers tbm: it redirects udm=12 to tbm=nws. For everything else, Google's own links now use udm. Our Google Search parameters reference covers tbm and the other URL parameters (gl, hl, tbs, uule), and the UULE generator builds the location parameter for you.
