Meta Description
I stopped obsessing over meta description length and started worrying about whether Google would even use mine.
Start here
- Write each meta description uniquely for every page, summarising the specific content rather than copying a template.
- Keep the length under 160 characters, but expect mobile truncation around 120 characters in search results.
- Include the page's main keyword naturally, but prioritise a compelling reason for the searcher to click.
- Check whether Google is rewriting your meta descriptions in Search Console's performance report.
- Add a clear call to action such as 'Learn how' or 'Get started' when the query signals intent to act.
Plain-English take
A meta description is an HTML meta tag placed in the page's <head> section. Its job is to summarise the page content in a readable way, typically shown as the snippet under the title in search results. It does not directly affect rankings — Google has said that for years. What it does influence is click-through rate. A well-written description can make someone choose your result over another. A bad or missing one often leads to Google auto-generating a snippet from your page, which may or may not help. I have seen pages where rewriting the description increased CTR by 8% in Search Console, but only when the original was poor. The key is to match the search intent: if someone searches 'buy gardening shoes', your description should mention buying, not just the benefits of gardening. I aim for around 155 characters, but I check how it appears on mobile because Google truncates sooner there. The description should be unique per page — duplicate descriptions waste an opportunity and can confuse Google about which page is more relevant. I include the main keyword naturally, but I do not force it if it breaks readability. The goal is to convince a human to click, not to satisfy a bot.

When it actually matters
Meta descriptions matter most when the search intent is commercial or transactional. If a user is comparing options or ready to buy, the description can tip the scale. For informational queries, Google often pulls the snippet from the page content anyway, so my effort may be wasted. I check the SERP for the query: if the top results all show custom descriptions, I make sure mine stands out. If they show auto-generated snippets, I prioritise other tasks. One example: I optimised meta descriptions for a client's product category pages. The pages with custom descriptions that included a price, a promise ('Free shipping') and a call to action saw a 12% higher CTR than those with default descriptions. But for blog posts answering 'how to' queries, Google rewrote the snippet 70% of the time. So I now focus effort on pages that already attract clicks and where the snippet is likely to be shown as written. That means checking the URL in search results manually or using Search Console to see how often your description appears. If it is frequently rewritten, your content probably needs to better match the query, or your description is too generic. I also pay attention to the relationship between the meta description and the [SEO title](/seo-title/) — they should work together to form a coherent entry in the search results. This is part of a broader [On Page SEO](/on-page-seo/) practice.
What I got wrong
I used to think meta descriptions were a ranking factor. I spent hours crafting them, stuffing keywords, hitting exactly 160 characters. I learned the hard way that Google ignores length limits and often rewrites whatever you put. My biggest mistake was copying a format from a competitor without checking whether it made sense for my audience. Every page deserves a description written for its specific content and the likely query. I also assumed that a meta description was a set-and-forget task. In reality, as your content changes or search trends shift, your description may become outdated. For example, I had a page about 'best running shoes' with a description saying 'updated for 2023' — that looked stale in 2025. Now I review descriptions during [content audits](/content-audit/) and update them when the page is refreshed. Another error: ignoring mobile truncation. I used to write descriptions that worked perfectly on desktop, but on mobile they were cut off mid-sentence. Now I test how the snippet appears on a mobile screen size. Finally, I used to measure success by whether the description existed, not by whether it improved [inbound marketing](/inbound-marketing/) metrics like conversion rate. A description that gets clicks but leads to a page that does not match the promise will damage trust. So now I write descriptions that state exactly what the page delivers, nothing more.

Quick answers
Does a meta description directly affect search rankings?
No, Google has confirmed meta descriptions are not a ranking factor. However, a compelling description can increase your click-through rate, which may indirectly influence rankings over time if it signals relevance and improves user engagement metrics.
How long should a meta description be in 2025?
The common recommendation is 150–160 characters for desktop, but mobile truncation often happens around 120 characters. I aim for about 145–155 characters to accommodate both. The most important thing is that the description reads naturally and matches the page content.
Why does Google sometimes rewrite my meta description?
Google may rewrite your description if it believes a different snippet from your page better matches the user's query. This happens often when your description is too generic, does not reflect the page content, or when the page contains a clear answer that the description does not mention.
