An exact-match keyword in the URL still helps a little, but only a little, and mostly for clarity rather than ranking. Google has confirmed it is a ranking signal while being blunt about the size: its own people call the words in a URL a “very, very lightweight” factor and say it isn’t worth restructuring a site to force keywords in. Once Google has crawled the page and read the actual content, the slug’s direct contribution to ranking is minimal, because the body text, the links, and the relevance signals carry far more weight than the address. The slug is not a lever you pull to climb the results.

Where it does earn its keep is the click. A slug that mirrors the search, a page about meta description length sitting at a short, readable, matching address, shows up in the result and tells the reader at a glance that the page is about their query, which can nudge the click before they have even read the meta description. A string of numbers and parameters tells them nothing. That is a clarity benefit and a small click-through benefit, not a ranking boost. It is also worth knowing that Google specifically adjusts so that stuffing keywords into a domain or slug doesn’t earn extra credit, which is why “keyword-rich URLs rank higher” overstates a signal that barely moves.

So give it the weight it earns: real, but minor, and pointed at the reader more than the algorithm. Keep your slugs short and descriptive, include the keyword when it fits naturally, and don’t contort the URL to force an exact match, because the readability is worth more to you than the tiny signal.
