Meta descriptions are mostly low‑ROI busywork today, especially at scale, because Google rarely shows what you write and they only matter after you’re already ranking and getting impressions.
1. Google usually rewrites them
-
Multiple independent studies on live SERPs have found that Google rewrites a large majority of meta descriptions, often well over half of all snippets.
-
Google has said for years that snippets are primarily generated from page content; the meta description is just one optional source they may use.
-
When your meta is vague, keyword‑stuffed, or just doesn’t answer the specific query, Google will happily grab something else from the page instead.
2. Snippets are query‑dependent
-
A single static 150–160 character description can’t possibly “fit” every query variation that page can rank for.
-
Google tailors the snippet to the actual query terms, pulling different sentences for different intents (informational, local, commercial, etc.).
-
That means the “perfect” generic meta often loses to an on‑page sentence that better matches what the user typed.
3. They don’t help you rank
-
Meta descriptions are not a ranking factor; they don’t directly help you move up in the SERPs.
-
You have to already rank and get impressions before anyone can even see the snippet, so for non‑visible pages they’re literally invisible.
-
If a page is buried on page 5, refining the meta won’t move the needle compared to improving content, links, or technical issues.
4. The opportunity cost is huge
-
Writing and maintaining thousands of unique descriptions is a massive time sink, especially for big blogs, ecommerce catalogs, and UGC sites.
-
When Google is going to overwrite a large share of them anyway, the marginal value per hour invested is tiny.
-
That same effort put into better content, internal linking, crawlability, and UX usually yields far more traffic and revenue.
