Essential Meta Tags

These meta tags directly influence how AI systems understand your page:

Title Tag

The most important single element for page identification:

<title>CRM Software for Small Business | Acme Corp</title>

• 50-60 characters optimal
• Primary keyword near the front
• Brand name at the end

Meta Description

A concise summary AI can use when citing your page:

<meta name="description" content="Acme CRM helps small B2B sales teams manage contacts, track deals, and close more sales. Starting at $29/month with a 14-day free trial." />

• 150-160 characters
• Include key facts (price, features, differentiators)
• Write for humans, not just keywords

Canonical URL

Tells AI which URL is the authoritative version:

<link rel="canonical" href="https://acme.com/crm" />

Essential for preventing duplicate content issues when content exists at multiple URLs.

Open Graph Tags

Open Graph meta tags are read by many AI systems for richer content understanding:

<meta property="og:title" content="CRM Software for Small Business" />
<meta property="og:description" content="Manage contacts, track deals, close more sales." />
<meta property="og:type" content="website" />
<meta property="og:url" content="https://acme.com/crm" />
<meta property="og:image" content="https://acme.com/images/crm-hero.png" />
<meta property="og:site_name" content="Acme Corp" />

Key Open Graph Types

website

Default for most pages

article

Blog posts, news, guides

product

Product pages

profile

Person or company pages

Article-Specific Meta Tags

For content pages, these additional tags help AI understand context and freshness:

<meta property="article:published_time" content="2025-01-15T09:00:00Z" />
<meta property="article:modified_time" content="2025-01-20T14:30:00Z" />
<meta property="article:author" content="https://acme.com/team/jane-smith" />
<meta property="article:section" content="Product Updates" />
<meta property="article:tag" content="CRM" />
<meta property="article:tag" content="Sales" />

Robots Meta Tag

Control how AI crawlers index your pages:

<meta name="robots" content="index, follow" />

Default behavior. Index the page and follow links.

<meta name="robots" content="noindex, follow" />

Don't index this page, but follow links to discover other content.

<meta name="robots" content="index, nofollow" />

Index the page but don't follow outbound links.

Complete Example

Here's a comprehensive meta tag setup for a product page:

<head>

  <meta name="description" content="Acme CRM helps small B2B sales teams manage contacts and close more deals. Starting at $29/month." />
  <link rel="canonical" href="https://acme.com/crm" />

  <!-- Open Graph -->
  <meta property="og:title" content="CRM Software for Small Business" />
  <meta property="og:description" content="Manage contacts, track deals, close more sales." />
  <meta property="og:type" content="product" />
  <meta property="og:url" content="https://acme.com/crm" />
  <meta property="og:image" content="https://acme.com/images/crm-og.png" />

  <!-- Twitter Card -->
  <meta name="twitter:card" content="summary_large_image" />
  <meta name="twitter:site" content="@acmecorp" />

  <!-- Indexing -->
  <meta name="robots" content="index, follow" />
</head>

Common Mistakes

✗

Duplicate titles across pages

Every page needs a unique, descriptive title.

✗

Keyword stuffing in descriptions

Write naturally. AI can detect and deprioritize spammy content.

✗

Missing canonical tags on paginated content

Use canonical tags to prevent duplicate content across pagination.

✗

Outdated Open Graph images

Ensure og:image URLs are valid and images represent current content.

Key Takeaway

Meta tags are your first impression.

AI systems often use meta tags to quickly understand and categorize your content before deep parsing. Accurate, descriptive meta tags improve how AI represents your pages in responses.
