How to Write Meta Descriptions With AI (Prompts and Examples)
Quick answer: To write a meta description with AI, give the AI the page title, main keyword, target reader and a summary of what the page actually contains, then ask for several options of roughly 150 to 160 characters that lead with the reader’s benefit and include the keyword naturally. Pick or blend the best one, check it matches the page, and paste it into your SEO plugin.
Key takeaways
- A meta description is the short page summary that can appear under your title in search results. Its job is to earn the click.
- Google has no formal length limit but trims snippets to fit the screen, so around 150 to 160 characters is a practical target.
- AI writes good options fast when it can see the real page content. Every description should be unique, accurate and reviewed by a person.
What is a meta description?
A meta description is an HTML tag, <meta name="description" content="...">, that summarizes a page. Search engines may show it as the snippet under your title. On WordPress, SEO plugins such as Rank Math or Yoast give you a box to write it for each post, so you never have to touch the code.
It is different from the title tag, which is the clickable headline in search results. The title says what the page is; the description persuades someone it is the right page for them.
Why meta descriptions still matter
- Clicks: a clear, relevant description can improve the share of people who click your result.
- Not a direct ranking factor: Google has said meta descriptions do not directly affect rankings. Their value is in persuading searchers.
- Social sharing: many sites also use the description, or a separate social description, when a link is shared.
How Google uses your meta description
According to Google’s own snippet documentation, snippets are usually created from the page content itself, and Google may show different snippets for the same page depending on the search. It uses your meta description when it gives a more accurate summary than the page text alone. That means:
- Google may rewrite your description, and that is normal.
- A precise, relevant description makes it more likely yours is used.
- There is no official character limit; snippets are truncated to fit the device width.
- Automatically generated descriptions are fine if they are human-readable, varied and specific to each page.
If you ever need to control snippets, Google supports the nosnippet and max-snippet robots settings and a data-nosnippet attribute, and most SEO plugins expose these as options.
What makes a good meta description
| Rule | Why |
|---|---|
| About 150–160 characters | Longer text is usually cut off on screen; treat this as a guide rather than a hard limit |
| Match the search intent | Someone searching “how to” wants steps; someone searching “best” wants a comparison |
| Lead with the benefit | Say what the reader gets, not just what the page is |
| Use active voice | “Learn how to…” or “Compare…” reads faster than passive phrasing |
| Include the main keyword naturally | Google often bolds words that match the search |
| Add specifics | Numbers, steps, prices you actually charge, opening hours or what is included stand out |
| Give a soft call to action | “See the chart”, “Get the checklist” or “Compare plans” tells people what to expect |
| Be accurate and unique | Misleading descriptions cause quick exits; duplicates make pages look interchangeable |
Avoid keyword stuffing, and avoid double quotation marks inside the description, which some systems cut off.
How to write meta descriptions with AI
Step 1: Look at the current search results
Search your main keyword and read the snippets that appear. What do they promise? What is missing? A description that offers something the others do not, such as a free chart, a specific number of steps or a clear answer, stands out.
Step 2: Give the AI the real page
AI writes much better descriptions when it can see the page, not just the title. Paste the title, the main keyword and the introduction or key points.
Step 3: Use a focused prompt
Write 5 meta descriptions for this page.
Title: [title]
Main keyword: [keyword]
Reader: [who searches this and what they want]
Page summary: [paste intro or key points]
Rules: 140–158 characters each, include the keyword naturally,
lead with the reader's benefit, active voice, one specific detail,
no clickbait, no quotation marks. Show the character count after each.Step 4: Check and choose
- Does it describe what is actually on the page?
- Would you click it over the other results for that search?
- Is the length right? AI character counts are sometimes off, so check your SEO plugin’s preview.
It is often best to combine the strongest opening from one version with the ending of another. For more on writing prompts like this, see how to write AI prompts.
Examples: before and after
Page: a guide to feeding a new puppy.
Weak: “This article is about how much to feed a puppy. Read on to learn more about puppy feeding.”
Better: “How much to feed a puppy by age and weight, with a simple feeding chart, portion tips and signs your puppy is eating too much or too little.”
Page: a comparison of two website builders.
Weak: “We compare two popular website builders in this post.”
Better: “Which website builder fits you? Compare pricing, templates, SEO tools and ease of use side by side, with a clear pick for beginners.”
Page: a local bakery’s homepage.
Weak: “Welcome to our bakery. We sell many baked goods.”
Better: “Fresh sourdough, pastries and custom cakes baked daily in East Austin. Order cakes online or visit us Tuesday to Sunday, 7am to 3pm.”
Writing meta descriptions for many pages
- Batch with AI: export URLs and titles, then give AI 10 pages at a time with a one-line summary of each. Review every result before pasting it in.
- Use templates for structured pages: SEO plugins let you build descriptions from variables such as the title or category. This works for large sets of similar pages, as long as each result is still readable and specific.
- Prioritize: start with your most important pages and the ones with the most search impressions.
Measuring and improving
You cannot run a true A/B test on Google’s results, but you can compare before and after. In Google Search Console, find pages with many impressions and a low click-through rate, rewrite their descriptions, note the date, and compare clicks and CTR over the following weeks. Changes in rankings or seasonality affect results too, so look for clear, sustained differences.
Tip: Pages with lots of impressions but few clicks are the best candidates for a rewritten meta description. Improving a strong page’s click-through rate is often faster than ranking a new one.
Frequently asked questions
How long should a meta description be?
There is no official limit, but Google trims snippets to fit the screen, so roughly 150 to 160 characters is a safe target.
Do meta descriptions affect SEO rankings?
Not directly. They influence whether people click your result, which is why they are still worth writing well.
Should I include keywords in meta descriptions?
Yes, naturally. Include the main keyword once, because matching words are often bolded, but never stuff keywords.
Why does Google show a different description?
Google generates snippets from your page when it thinks that better matches the search. Clear, accurate descriptions are more likely to be used.
Do all pages need a meta description?
Important pages should have one. For very large sites, prioritize key pages and use readable templates for the rest.
Can I use AI to write meta descriptions for my whole site?
Yes, as long as each one is unique, accurate for its page and reviewed by a person before it goes live.
