UULE Generator & Decoder

What is a UULE parameter?

UULE is a URL parameter used in Google Search to tell Google which location to use when ranking results. When you add uule=<value> to a Google Search URL, results are personalized as if you were searching from that location - useful for local SEO research, rank tracking, and SERP scraping.

UULE v1 - Location name encoding

UULE v1 encodes a Google canonical location name (like Austin, Texas, United States) into a URL-safe string. The algorithm is:

1. Base64-encode the location name.
2. Look up a single-character secret that corresponds to the length of the base64 string.
3. Prepend the fixed identifier w+CAIQICI, the length secret, and append the base64 string.

Example URL: https://www.google.com/search?q=coffee+shops&uule=w+CAIQICINQXVzdGluLFRleGFz

UULE v2 - Latitude/longitude encoding

UULE v2 encodes a precise geographic coordinate rather than a named location. Enter a latitude and longitude and the tool produces the parameter value ready to append to a Google Search URL.

UULE v2 is useful when you need to target a specific point on the map rather than a named location, such as tracking rankings for a business at a precise GPS coordinate.

How to use UULE with Google Search

Append the UULE parameter to any Google Search URL:

Combine it with gl (country code) and hl (language code) for the most accurate localized results.
