What meta descriptions are and where they appear
When you search for something on Google, each result has three main elements: the page title (the blue link), the URL, and a short description underneath. That description is the meta description.
It’s a piece of HTML that sits in the head of your page. It doesn’t appear on the page itself, only in search results and sometimes when your link is shared on social media. Most content management systems like WordPress have fields where you can write it without touching any code, usually through an SEO plugin like Rank Math or Yoast.
Here’s the thing that surprises a lot of people: meta descriptions are not a direct ranking factor. Google has confirmed this. They don’t use the text of your meta description to determine where you rank. But they absolutely influence your click-through rate (CTR), and CTR does matter because it determines how much of your ranking potential actually converts into visits.
Think of it this way. Ranking is getting your shop onto the high street. Your meta description is the window display that makes people walk in.
Character limits: how long should they be?
Google displays meta descriptions based on pixel width, not character count, which means the exact cutoff varies depending on the characters used. But as a practical guideline:
- Aim for 150-160 characters. This is the sweet spot where your description is long enough to be useful but short enough to avoid being truncated.
- Don’t go under 70 characters. A very short meta description looks incomplete and wastes the space Google gives you to sell the click.
- Mobile shows less. On mobile devices, descriptions are often cut shorter, closer to 120 characters. Front-load the most important information.
If your description gets cut off mid-sentence, it looks sloppy and can reduce clicks. Write with the limit in mind and make sure the message works even if the last few words get chopped.
Why they matter for CTR
Imagine you search for “how to improve website speed” and two results appear:
Result A: “Website speed. We offer website services including speed optimisation, web design, and SEO. Contact us today for a free quote.”
Result B: “Most website speed problems come down to three things: images, plugins, and hosting. Here’s how to test yours and fix the biggest issues in under an hour.”
Which one would you click? Result B tells you exactly what you’ll get, addresses the search intent directly, and promises a specific, practical outcome. Result A could be any generic agency page.
Studies have consistently shown that well-crafted meta descriptions can improve CTR by 5-10% or more compared to generic or auto-generated ones. On a page that gets 1,000 impressions a month, that’s an extra 50-100 visits without improving your ranking position at all.
Your meta description is the pitch that happens between ranking and clicking. A good one turns impressions into visits. A bad one wastes every ranking you’ve earned.
How to write a good meta description
There’s no magic formula, but there are principles that consistently work:
Match the search intent
This is the most important thing. Your description should clearly signal that the page contains what the searcher is looking for. If someone is searching “how to” do something, your description should promise practical steps. If they’re searching for a specific service, your description should confirm you offer it and give a reason to choose you.
Understanding search intent comes back to solid keyword research. When you know what people are actually typing and why, you can write descriptions that speak directly to their need.
Include your target keyword
When someone searches for a term and it appears in your meta description, Google bolds it. This visual emphasis makes your result stand out and signals relevance. Don’t stuff keywords in unnaturally, but do include the primary keyword once.
Lead with the benefit or answer
Don’t waste the first 50 characters on your company name or generic waffle. Start with what the reader will get from the page. Will they learn something? Save money? Solve a problem? Say so upfront.
Include a call to action where appropriate
For service pages and landing pages, a soft call to action can work well: “Find out how,” “See our approach,” “Get a free quote.” For informational content, phrases like “Learn the practical steps” or “See the full breakdown” work better than “Contact us today.” Match the CTA to the page type.
Be specific
Numbers, time frames, and concrete details make descriptions more compelling. “5 proven techniques” is more clickable than “several useful tips.” “Takes 10 minutes to implement” is more compelling than “easy to do.”
Write for humans, not search engines
This should go without saying, but meta descriptions stuffed with keywords and written in robot-speak actively deter clicks. Write naturally. Write as if you’re telling a friend what the page is about and why it’s worth reading.
Common mistakes to avoid
- Duplicate descriptions across multiple pages. Every page should have a unique meta description. If you copy and paste the same one across your site, you’re wasting opportunities and confusing search engines about which page to show for which query.
- Leaving them blank. If you don’t write a meta description, Google will auto-generate one from your page content. Sometimes it does an acceptable job. Often it pulls a random, contextless sentence that doesn’t sell the click at all.
- Writing descriptions that don’t match the page. If your description promises “a complete guide to local SEO” but the page is a 200-word sales pitch, you’ll get clicks but you’ll also get immediate bounces. Misleading descriptions hurt your engagement metrics and your credibility.
- Keyword stuffing. “Best SEO agency, SEO services, cheap SEO, SEO company UK, affordable SEO.” Nobody clicks that. It screams spam. One natural inclusion of your keyword is plenty.
- Being too vague. “We provide a range of digital services to help your business grow online.” That could describe any agency on the planet. Be specific about what the page actually offers.
If you’ve got an existing website and you’re not sure how your meta descriptions look, running a website audit will flag pages with missing, duplicate, or poorly written descriptions.
When Google rewrites your meta description
Here’s something that frustrates a lot of people: even when you write a perfectly good meta description, Google sometimes ignores it and shows something else instead. Research suggests Google rewrites meta descriptions around 60-70% of the time.
Why does Google do this? Because their algorithm tries to match the snippet to the specific query the person searched. If your meta description talks about your overall service but the search query is about a specific aspect of that service, Google might pull a sentence from your page content that it thinks better answers the query.
You can’t completely prevent this, but you can reduce how often it happens:
- Write descriptions that closely match your primary keyword. The more relevant your description is to the queries you’re targeting, the more likely Google is to use it.
- Make your description genuinely better than what Google would generate. If your auto-generated snippet is better than what you wrote, you’ve got bigger problems.
- Include the kind of language searchers use. If people search for “cheap” or “near me” or “for beginners,” and it’s relevant to your page, reflecting that language in your description increases the chance Google uses it.
Even when Google rewrites your description, having a well-written one isn’t wasted effort. Google still uses it as a starting point and will show it for some queries. And it serves as a useful exercise in clarifying what each page is actually about.
Google rewrites meta descriptions more often than not. Write them anyway. A strong description is still your best chance of controlling how your pages appear in search results.
A structured approach for your whole site
Rather than tackling meta descriptions page by page at random, here’s a systematic approach:
- Start with your highest-traffic pages. Check Google Search Console to see which pages get the most impressions. These are the pages where a better meta description will have the biggest impact on clicks.
- Prioritise pages with high impressions but low CTR. These are the pages that are ranking and being seen but not getting clicked. A better description could unlock traffic you’re already earning the right to receive.
- Write descriptions for all service and product pages. These are your commercial pages. Every one should have a hand-written, intent-matched description.
- Cover your blog posts. Especially the ones ranking on page one or two. A compelling description can be the difference between position 6 getting a click or being scrolled past.
If you’re running a WordPress site with an SEO plugin, you can see which pages are missing descriptions or have issues in the plugin’s dashboard. For dentists or other service businesses, our SEO checklist for dentists shows how this fits into a broader local SEO approach, and the same principles apply to any industry.
Action steps
- Audit your current meta descriptions. Use your SEO plugin or a tool like Screaming Frog to identify pages with missing, duplicate, or too-short descriptions.
- Check Search Console for opportunity pages. Find pages with high impressions but below-average CTR. These are your quick wins.
- Write new descriptions for your top 10 pages. Follow the principles above: match intent, include your keyword, lead with the benefit, be specific, and stay within the character limit.
- Monitor the impact. After a couple of weeks, check those pages in Search Console again. Has CTR improved? If so, keep going with the rest of your site.
- Make it part of your publishing process. Every new page or post should include a hand-written meta description before it goes live. Don’t leave it to chance. The meta description step sits alongside everything else worth checking in our pre-publish content checklist.
Meta descriptions are one of those small things that add up. They won’t transform your SEO overnight, but they’re free, they’re entirely within your control, and they directly affect how many people click through to your site. That’s worth the few minutes it takes to write them well.
