SEO Meta Description
A meta description is an HTML <meta> tag in a page’s <head> that provides a short summary of the page and may appear as the search result snippet under the title.
Key takeaways
- Meta descriptions appear as snippet text under the title in search results
- They are not a direct ranking factor but influence click-through rate
- Google may rewrite the snippet, so write for humans first
- Keep between 150–160 characters to avoid truncation
- Must be unique per page and match search intent
It helps searchers decide whether to click your result, improving organic click-through rate even though it is not a direct ranking factor.
Example
Page: Guide to planting tomatoes
Meta description: > Learn how to plant tomatoes in your garden. Step-by-step instructions, best soil types, watering tips, and common mistakes to avoid.
This description appears in Google search results as the snippet below the title, giving searchers a clear preview of the page content.
When should I use this?
Use a meta description on every page you want to appear in search results. It is especially important for:
- Landing pages – to attract clicks from search users
- Product pages – to include price, brand, or key features
- Blog posts – to summarize the article and match search intent
- Local pages – to include location or contact details
What it is not
- A direct ranking factor – Google does not use meta descriptions to rank pages
- A guaranteed snippet – Google may rewrite it based on the query
- A place to stuff keywords – keyword lists hurt readability and may trigger rewriting
- The same as the title tag – the title tag is a separate HTML element with different SEO impact
Quick start
- Identify the page topic – Understand the main subject and search intent.
- Write a concise summary – Use 150–160 characters that describe the page accurately.
- Include relevant details – Add price, author, date, or location if useful.
- Use natural language – Write for humans, not search engines.
- Make it unique – Never duplicate a meta description across pages.
- Preview in search – Use a tool like Moz Title Tag Preview Tool to check truncation.
Common mistakes
- Using duplicate meta descriptions across many pages
- Writing keyword lists instead of a readable summary
- Making the description too long, increasing truncation risk
- Letting AI or templates produce descriptions without human review for accuracy and uniqueness

FAQ
Does Google always use the meta description as the snippet?
No. Google may rewrite the snippet based on the user's query or page content. The meta description is a strong suggestion, not a guarantee.
What is the ideal length for a meta description?
Google does not enforce a strict limit, but most SEOs recommend 150–160 characters to reduce the chance of truncation in search results.
Can I use the same meta description on every page?
No. Duplicate meta descriptions are a common mistake. Each page should have a unique description that accurately summarizes its content.
