What each tag does
<title>: the clickable headline in search results and the browser tab. The single most important on-page SEO element.meta description: the snippet under the title. It does not affect rankings directly, but a good one gets more clicks.link rel="canonical": tells search engines which URL is the main version, so copies with tracking parameters orwwwvariants do not compete.og:tags: Open Graph controls the title, description and image when the page is shared on Facebook, LinkedIn, WhatsApp, Slack and more.twitter:card: asks X for a large image card. X falls back to the Open Graph tags for the rest.robots noindex: keeps a page out of search results, for thank-you pages, internal search results or staging copies.
Pair these with a sitemap and a robots.txt so search engines can find every page you want indexed.
Frequently asked questions
How long should a title tag be?
Google cuts titles off by width, not characters: roughly 600 pixels on desktop, which is about 50 to 60 characters. Put the main keyword near the start so it survives truncation. This generator measures the pixel width and shows where Google would cut it.
How long should a meta description be?
About 150 to 160 characters (around 920 pixels on desktop) before Google truncates it. Google often rewrites descriptions using text from the page, but a clear, specific description is still used most of the time and improves click-through.
What size should an Open Graph image be?
1200 × 630 pixels (a 1.91:1 ratio) works for Facebook, LinkedIn, X and most messaging apps. Keep important text away from the edges and the file under 5 MB; under 300 KB is better for fast previews.
Do meta keywords still matter?
No. Google has ignored the meta keywords tag for over a decade, and other major search engines give it little or no weight. This generator leaves it out.
