Meta tags are snippets of code that tell search engines and social media platforms about your page. While some meta tags are crucial for SEO, others are completely ignored. Let's separate the essential from the obsolete.
Meta Tags That Actually Matter
Title Tag
The title tag isn't technically a meta tag, but it's the most important element for SEO. It appears in:
- Browser tabs
- Search engine results
- Social media shares
Best practices:
- Keep it under 60 characters to avoid truncation
- Include your target keyword near the beginning
- Make it compelling—it's your first impression in search results
- Each page should have a unique title
Meta Description
While not a direct ranking factor, meta descriptions affect click-through rates:
<meta name="description" content="Your compelling description here">Guidelines:
- 150-160 characters maximum
- Include a call to action
- Naturally incorporate relevant keywords
- Accurately describe the page content
- Unique for every page
Viewport Meta Tag
Essential for mobile responsiveness:
<meta name="viewport" content="width=device-width, initial-scale=1">Without this, mobile users see a tiny desktop version of your site.
Robots Meta Tag
Controls how search engines index your pages:
<meta name="robots" content="index, follow">Options include:
- index/noindex: Whether to include in search results
- follow/nofollow: Whether to follow links on the page
- noarchive: Don't show cached version
- nosnippet: Don't show description in results
Social Media Meta Tags
Open Graph (Facebook, LinkedIn)
Control how your content appears when shared:
<meta property="og:title" content="Your Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://example.com/image.jpg">
<meta property="og:url" content="https://example.com/page">
<meta property="og:type" content="website">Twitter Cards
Twitter-specific formatting:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="Your Title">
<meta name="twitter:description" content="Your description">
<meta name="twitter:image" content="https://example.com/image.jpg">Our meta tags generator creates all these tags automatically.
Meta Tags That Don't Matter for SEO
These are largely ignored by search engines:
Keywords Meta Tag
Google confirmed in 2009 they don't use it. Don't waste time on it:
<!-- Don't bother -->
<meta name="keywords" content="useless, ignored, waste of time">Author Tag
Not a ranking factor, though sometimes displayed:
<meta name="author" content="John Doe">Revisit-After
Search engines crawl on their own schedule:
<!-- Ignored -->
<meta name="revisit-after" content="7 days">Writing Effective Titles and Descriptions
Title Tag Formulas That Work
- How-to: "How to [Achieve Goal] in [Timeframe]"
- List: "[Number] Best [Things] for [Benefit]"
- Question: "What Is [Topic]? Complete Guide"
- Year: "[Topic]: The Complete Guide [Year]"
Description Writing Tips
- Start with the most important information
- Use active voice
- Include a value proposition
- End with a soft call to action
- Don't stuff keywords unnaturally
Technical Considerations
Character Encoding
Always specify UTF-8:
<meta charset="UTF-8">Canonical Tags
Prevent duplicate content issues:
<link rel="canonical" href="https://example.com/preferred-url">Language and Region
For international sites:
<html lang="en">
<link rel="alternate" hreflang="es" href="https://example.com/es/">Common Meta Tag Mistakes
- Duplicate titles/descriptions: Every page needs unique tags
- Missing on important pages: Home, product, and landing pages need optimization
- Too long or too short: Stay within character limits
- Keyword stuffing: Write for humans first
- Mismatched content: Tags should accurately reflect page content
- Forgetting social tags: Missing Open Graph means poor social shares
