Essential Meta Tags

Title Tag
The title tag is the single most important on-page SEO element. It appears in search results, browser tabs, and social shares.
Best practices:
- Keep under 60 characters to avoid truncation.
- Place your primary keyword near the beginning.
- Include your brand name at the end.

Meta Description
The meta description doesn't directly affect rankings but influences click-through rates. It's your 155-character pitch to searchers.
Best practices:
- Accurately summarize the page content.
- Include a call to action.
- Include your target keyword (Google bolds matching terms).
- Unique per page.
Open Graph Tags
Open Graph controls how your pages appear when shared on Facebook, LinkedIn, and other social platforms:
og:title— Title shown in social cards.og:description— Description shown in social cards.og:image— Image displayed (recommended: 1200x630px).og:url— Canonical URL of the page.og:type— Content type (website, article, product).
Twitter Cards
Twitter uses its own meta tags (twitter:card, twitter:title, etc.) but falls back to Open Graph tags when Twitter-specific tags are absent.
Common Mistakes
- Duplicate titles across many pages.
- Missing og:image (social shares show no preview).
- Title tag too long (truncated with ...).
- Meta description too short or generic.
