Meta Description vs Keywords: What's the Difference in SEO?

A meta description is the short summary shown under your title in search results, written to earn the click. Meta keywords are an old HTML tag that once listed a page's target terms, but Google has ignored it since 2009. The two tags are not interchangeable, and only one of them still matters for your rankings and click-through rate today.

Key takeaways

• A meta description is visible in search results and written for people. Meta keywords are hidden in the page's HTML and were written for crawlers.
• Google confirmed in 2009 that it disregards the keywords meta tag completely, and that has not changed since.
• A meta description is not a direct ranking factor either, but it shapes click-through rate, which Google does track.
• Ahrefs analyzed 20,000 keywords and found Google rewrites the meta description it is given roughly 62.78% of the time, so what you write is a strong hint, not a guarantee.
• Your target keyword still belongs in the meta description, written naturally for a reader rather than listed like a tag.
• Most modern platforms, including WordPress and Shopify, no longer ship a meta keywords field by default, because there is nothing left for it to do.

What is a meta description?

A meta description is an HTML tag, <meta name="description">, that gives a short summary of a page's content. Search engines often display it under the title link on the results page, so it works as free ad copy that persuades someone to click. It is not visible on the page itself, only in the search snippet, the browser tab preview, and some social share cards.

Because it sits in the page's metadata rather than the visible body copy, a meta description does not affect how the page reads for a visitor. It only shows up in the moment someone is deciding whether to click through from a results page, which is exactly why it is worth writing well.

What are meta keywords?

Meta keywords are an HTML tag, <meta name="keywords">, that once let a page owner list the terms they wanted to rank for, separated by commas. The tag is invisible to visitors and, for the search engines that matter, invisible to rankings too. Google's own Search Central blog confirmed in September 2009 that it disregards keyword meta tags completely, and Bing has given similar guidance for years.

The tag was popular in the 1990s, back when early search engines really did scan it to understand a page's topic. That trust got abused fast: site owners stuffed the tag with hundreds of irrelevant terms to game rankings, so search engines stopped trusting it and eventually stopped reading it at all. What is left today is a piece of HTML that a handful of older content systems still generate out of habit, with no effect on how the page performs.

Meta description vs meta keywords: the core differences

Side by side, the two tags do almost nothing alike. One is a visible pitch to a human. The other is a dead label search engines stopped reading years ago.

The practical takeaway: spend zero time on meta keywords and all your on-page attention on the tags that still work, starting with the title tag, the meta description, and a clean URL slug.

Does Google still use the meta keywords tag?

No. Google's Search Central blog stated in September 2009 that its web search disregards keyword meta tags completely and that they have no effect on search rankings. The policy has not changed since, and Google's search advocates have repeated the same guidance in public forums many times over the years. Bing does not use the tag as a positive ranking signal either, and has said it may only factor into spam detection in rare cases.

In other words, there is no version of "using meta keywords correctly" that helps you rank. The tag is not a lesser tool you are underusing. It is a retired one.

Will Google always show the meta description you write?

Not always. Ahrefs analyzed 20,000 keywords and found Google replaces the meta description a site wrote with its own auto-generated snippet roughly 62.78% of the time, pulling text straight from the page instead. That number rises further for long-tail, highly specific queries, where Google is more likely to find a passage on the page that answers the exact question better than a generic summary can.

None of that makes writing a meta description pointless. A rewritten snippet is Google's best guess at what will satisfy that specific searcher, but you still control the odds. A tight, on-topic description that matches the query gives Google a strong candidate to keep, and it is what shows for every query where Google decides your version is already the best answer.

How keywords still belong in your meta description

This is where the confusion in "meta description vs keywords" usually comes from. People hear that the keywords tag is dead and assume keywords no longer matter for meta descriptions either. That is wrong. The meta keywords tag is dead. Using your target keyword inside the meta description is still good practice, just for a completely different reason: relevance and click-through, not indexing.

Google often bolds the searcher's query terms when they appear in your description, which draws the eye and signals an exact match for what the person typed. A description built around your target keyword and the reader's intent earns more clicks than a vague, generic summary, even though the description itself does not move your ranking position.

How to write a meta description that includes your keyword

Treat the meta description as a one-sentence pitch, not a keyword slot. These steps keep it effective for both readers and search engines.

1. Lead with the reader's intent. State what they will get or learn in the first few words, before any brand name or filler.
2. Place your keyword early. Put your primary keyword or a close natural variant within the first 120 characters, so it shows even if the snippet gets cut off on mobile.
3. Use it once. Mention the keyword a single time. Repeating it looks like leftover meta keywords thinking and can make Google discard the description entirely.
4. Match the actual page content. Only promise what the page delivers. A mismatched description gets ignored by Google and, worse, disappoints the visitor who does click.
5. Stay inside 140 to 160 characters. Our guide on how long a meta description should be breaks down the exact desktop and mobile limits.
6. Write a different description for every page. Duplicate descriptions across pages waste the opportunity and can make Google fall back to auto-generating one anyway.

Meta description examples: weak vs strong

The difference between a weak and a strong description is almost always specificity. A vague summary reads like a placeholder. A strong one reads like it was written for one exact search.

Common mistakes when people confuse the two tags

• Filling in meta keywords and skipping the meta description. This is backward. The tag that does nothing gets attention while the tag that earns clicks stays blank.
• Stuffing the meta description like an old keywords tag. Repeating a term three times in one sentence reads as spam to a person and can push Google to write its own version instead.
• Copying the same description across many pages. Each page needs its own pitch, matched to its own query.
• Assuming a good description guarantees a ranking boost. It does not. It boosts click-through on the ranking you already have, which is still valuable, just a different lever.
• Leaving the description blank and hoping Google writes a good one. Google's auto-generated snippet is a fallback, not a strategy. Write your own first.

Frequently asked questions

What is the difference between a meta description and meta keywords? A meta description is the short summary that shows under your title in search results, written to earn clicks from real people. Meta keywords are a hidden HTML tag that once listed target terms for search engines. Only the description still does anything today.

Does Google use the meta keywords tag for ranking? No. Google's Search Central blog stated in September 2009 that it disregards keyword meta tags completely, and that guidance has never changed. You can leave the tag out entirely with no ranking impact.

Should I still add a meta keywords tag to my pages? There is no upside either way. Most modern platforms such as WordPress and Shopify do not even include a keywords field by default anymore, which reflects how little the tag matters now.

Do meta descriptions need to include my target keyword exactly? Not exactly, but naturally. Include your main keyword or a close variant once, ideally near the start, and let the rest of the sentence read like normal writing rather than a keyword list.

How long should a meta description be? Aim for roughly 140 to 160 characters so it does not get cut off on desktop or mobile results. Our guide on how long a meta description should be covers the exact limits for each device.

Will Google always show the meta description I write? No. Ahrefs analyzed 20,000 keywords and found Google rewrites the meta description roughly 62.78% of the time when it finds text on the page that answers the query more precisely. A strong, on-topic description still improves the odds Google keeps it.

Do meta keywords help with Bing or other search engines? No major search engine treats the tag as a positive ranking signal today. Bing has said it may factor into spam detection in rare cases, but it does not boost rankings anywhere, so there is no practical reason to maintain it.

Can I use more than one keyword in a single meta description? Yes, as long as it still reads naturally. Weave in your primary keyword plus one or two close variants or related terms, rather than listing every keyword you want to rank for.

What happens if my CMS still shows a meta keywords field? Nothing harmful happens if you fill it in, since Google ignores it, but it will not help either. Spend that time refining your meta description and title tag instead, since those are the tags that still influence clicks.

What to do next

Stop spending time on the meta keywords tag and put that effort into your meta description instead. Open your most important pages, check whether each one has a unique, keyword-relevant description under 160 characters, and rewrite the ones that are missing, generic, or duplicated.
