1 What is a meta tag?
Meta tags are pieces of code in the <head> section of your page that describe the page to browsers, search engines and social networks. Visitors never see them directly, but Google uses them to decide what to show in search results.
The three most important meta tags are:the title tag, the meta description, and the Open Graph image. These control how your page looks in Google search and on social media.
2 Title tags
The title tag is the most important on-page SEO element. It is the clickable headline in Google search results and the text shown on browser tabs.
| Rule | Detail |
|---|---|
| Length | 50-60 characters (Google truncates beyond ~600px wide) |
| Keyword | Primary keyword near the start when natural |
| Brand | Brand at the end after a pipe or dash |
| Uniqueness | Every page must have a different title tag |
| Match | Title should match what the page actually delivers |

The meta description is the 1-2 sentence summary shown under your title in search results. It does not directly affect rankings but heavily affects click-through rate.
| Rule | Detail |
|---|---|
| Length | 140-160 characters (Google truncates around 155-160) |
| Action | Include a call-to-action |
| Specific | Mention specific benefits or numbers, not vague claims |
| Unique | Every page needs its own description |
| Truthful | Promise only what the page actually delivers |
Google may rewrite your descriptionbased on the search query. Write the best version you can but don’t obsess if Google shows different snippets for some queries.
