Unnatural Links

Backlinks that weren't earned through genuine editorial decisions — typically purchased, automated, or placed through manipulative schemes. Google issues manual actions specifically for "unnatural links to your site" and "unnatural links from your site."

UGC Link Attribute

The rel="ugc" tag that flags a link as originating from user-generated content — such as forum posts, blog comments, or community submissions. UGC links signal to search engines that the site owner didn't place the link editorially.

Universal Search

Google's blending of images, videos, news, maps, and other content types into a single set of organic results. Universal Search means you're not just competing against other web pages — you're competing against every content format for the same SERP real estate.

URL Rating (UR)

A page-level metric (0–100) that estimates the strength of an individual URL's backlink profile. While domain rating measures the overall site, URL Rating zooms in on how well-linked a specific page is.

URL Slug

The readable, descriptive portion of a URL that follows the domain and path (e.g., /seo/glossary/backlinks). Clean, keyword-relevant slugs improve user experience and give search engines an additional relevance signal.

User Intent

What a searcher actually wants to accomplish when they type a query — whether that's finding an answer, comparing products, or completing a transaction. Aligning your content with user intent is the single most important factor in earning and keeping rankings.
