meta tags
Also called: meta elements, meta element, HTML meta tags
Meta tags are HTML <meta> elements in a page's <head> that describe the page to browsers and search engines. Google supports a specific set (including description, robots, and viewport) and ignores others, such as the keywords meta tag.
Meta tags sit in the <head>, invisible to readers but parsed by crawlers and browsers. Google publicly lists which ones it supports and what each does; anything outside that list is ignored.
The ones that matter for SEO
- Meta description: not a ranking factor. Google says it “sometimes uses the meta description HTML element if it might give users a more accurate description of the page than content taken directly from the page.” A tight, unique description improves click-through from the snippet.
- Robots meta tag: controls indexing and snippet behavior (
noindex,nofollow,max-snippet, and so on). When therobotsandgooglebottags conflict, the more restrictive one wins. - Viewport: its presence signals to Google that the page is mobile friendly.
- Charset: declares encoding; Google recommends UTF-8.
- google-site-verification: proves ownership in Search Console.
The keywords meta tag is dead for Google ranking. Google confirmed in 2009 that it does not use it, and that has not changed.
One common mix-up: the <title> element is not technically a <meta> tag, but it lives in the same <head> and does the heavy lifting for the clickable title link in search. Treat title and description as a pair.
A minimal, correct head:
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Fresh Ground Coffee | Roasted Daily</title>
<meta name="description" content="Single-origin beans roasted to order, shipped within 24 hours.">
<meta name="robots" content="index,follow">
</head>How it affects your traffic
Meta tags are cheap to get right and expensive to get wrong. A missing or duplicated meta description hands Google a worse snippet, which drags click-through even when the page ranks well; a stray noindex or bad robots directive can drop a page out of the index entirely. Auditing and rewriting title and description tags across a site is one of the first passes in an on-page SEO engagement, because it moves clicks and protects indexation without waiting on new content or links.
