How long should a meta description be?

150-160 characters for desktop SERPs. Mobile SERPs truncate around 120 characters. The AI Meta Description Generator stays in the 150-160 range and always leads with the most important hook in the first 120 characters so nothing critical is lost on mobile.

Should I include the target keyword?

Yes — once, naturally, ideally in the first 60 characters. Google bolds matching query terms in the SERP snippet, which improves CTR. Avoid stuffing the keyword multiple times — Google detects it and may rewrite your description entirely.

Why does Google rewrite my meta description sometimes?

Google rewrites about 70% of meta descriptions in production because the page meta doesn't match the user's search intent for that specific query. Strong descriptions reduce — but don't eliminate — the rewriting. The best defense: write multiple compelling variants and ship the one that best matches your primary query.

What is a meta description?

A meta description is the short summary of a webpage that appears below the title in search results. Google uses it to give searchers a preview of what is on the page before they click. It is set via the HTML <meta name="description" content="..."> tag in the <head> of the page.

Does the meta description affect SEO?

Indirectly. Google has confirmed the meta description is not a direct ranking factor. But a compelling meta description increases click-through rate (CTR) from search results — and CTR is strongly correlated with ranking. Well-written metas on page-1 pages routinely lift them 1-3 positions over a few weeks.

Why does Google rewrite meta descriptions?

Google rewrites ~70% of meta descriptionsat the SERP level — usually because the user's specific query doesn't match what your meta is pitching. The fix isn't to write zero metas (then Google has nothing to fall back on). The fix is to write tight, specific metas that match your dominant search query. Strong descriptions still get rewritten sometimes, but at much lower rates.
