AI Meta Description Generator

You describe the page in the form: topic, primary keyword, audience, page type, search intent, tone, brand and notes. The generator asks a language model for exactly five meta descriptions, between 120 and 155 characters where possible, and tells it to avoid clickbait, unverifiable claims and keyword stuffing. Each draft comes back with its character count and a copy button.

A description has about two lines to work with, so the Notes field does more work here than it does for a title. That space is where a searcher compares results: the price or price range, delivery or turnaround time, what is included, how long the task takes, who the page is for. The generator does not read your page, so every fact it uses has to come from you. If a draft states something you never supplied, such as a guarantee, a discount or a number, delete it.

Runs share one limit with the SEO title generator: 20 an hour and 25 a day from one IP address. Each run gives different wording, so two runs give you ten drafts to choose from and combine.

A draft over 155 characters is marked “Likely long for Google display”, with its count shown against 155. A draft under 120 is marked “May be too short to use the available SERP space”, against 120. Anything in between gets no mark.

Google sets no limit of its own. Its snippet documentation says there is no limit on how long a meta description can be, and that the snippet is truncated as needed, typically to fit the device width. Descriptions are cut by pixel width, not character count, and a phone shows less than a desktop. So 155 is a convention many tools share, not a boundary Google enforces.

The convention misses in both directions. In the worked example below, a 151-character draft passes the generator’s check but measures about 933 pixels in Arial at 14 pixels, past the 920-pixel desktop estimate the title and meta description checker uses. A 160-character draft gets the warning and would be cut too. On the checker’s 680-pixel mobile estimate, each of those drafts is cut after roughly the first 100 characters.

So the practical rule is about order, not length. Put the whole point of the page in the first sentence, keep that sentence to about 100 characters, and use the rest for detail you can afford to lose on a phone.

Google’s snippet documentation says snippets are primarily created from the page content itself, and that Google sometimes uses the meta description when it gives a more accurate description of the page than text taken from the page. The snippet can differ from one search to the next, because Google picks the text that best answers that particular query.

So one page can show your description for its main query and a sentence from the body for a narrower one. That is not a failure. Write the description for the searches that bring the most impressions; the long tail will often get a passage from the page instead, and a clearly written page gives Google good passages to choose from.

The description does not affect ranking. Google said so in 2009, in the post announcing that it ignores the keywords meta tag: it sometimes uses the description meta tag for snippets, but not in ranking. Its value is the click it earns from people who already see your result.

Use these to keep text out of results, such as a price that changes every day. None of them forces Google to show your description instead of page text.

Google’s snippet documentation recommends a unique description for each page, one that summarizes the page and includes relevant, specific information. Its examples of weak descriptions match the drafts you should delete: a list of keywords, the same description on every page, text that does not summarize the page, and text so short it says nothing. For large sites it suggests generating descriptions programmatically from each page’s own data, and for product pages, focusing on the specific details of the product.

A page ranks for many queries, but most of its impressions usually come from a few. In Search Console, open Performance → Search results, click the page on the Pages tab, then switch to the Queries tab and sort by impressions. Write the description for the top few, in their words where they fit naturally.

Then write for the decision the searcher is making. That depends on intent, which is why the intent setting matters as much here as it does for titles.

Leave the title to do its own job. The title names the page; the description adds what the title has no room for. A description that repeats the title wastes the second line, and the title and meta description checker flags an exact repeat.

The business, inputs and drafts are illustrative. The counts and warnings are what the generator’s rules give for these exact strings, and the widths are measured in Arial at 14 pixels against the checker’s 920-pixel desktop and 680-pixel mobile estimates.

Inputs: page topic “Water heater repair and replacement service page for Tulsa homeowners”. Primary keyword “water heater repair tulsa”. Page type “Service page”. Intent local, tone clear, brand “Hartley Plumbing”. Notes: “Same-day service Monday to Saturday. Tank and tankless. Flat-rate quote before work starts. Licensed since 1998.”

Draft 1 wins for the main query because it leads with the service and the place, then gives the three facts that set the business apart. Draft 5 is worth keeping for a separate “no hot water” page if the site has one. Before publishing either, check each fact with the owner: same-day service six days a week is a promise searchers will hold you to.

Every SEO plugin lets you set a description template per content type, built from variables such as the excerpt, the title or a custom field. A template beats having no description only when its variables hold real, page-specific information.

Use a template where pages differ by data: products, listings, locations, events, recipes. Build it from the fields that change per page, such as product name, size, price or area served, which is what Google means by generating descriptions programmatically. Avoid templates that wrap the same sentence around the title, such as “Read our latest article about [title] on our blog”: every page then reads alike, which is one of the weak patterns Google names.

Write by hand for the pages that matter most: the ones with the most impressions in Search Console, and the ones where Google is showing a passage you would not have chosen. On a typical blog that is a few dozen pages, not all of them. Generate drafts for those one page at a time, with real facts in Notes.

WordPress has no meta description field of its own; it comes from your SEO plugin. Menu names below are as of October 2026.

A description earns clicks only after Google shows it, so verify in two steps: that the page serves the new text, then that results use it.

Skip pages that never appear in results: anything set to noindex, cart and account pages, thank-you pages, internal search results. Skip pages with a nosnippet rule, since no description will show. Skip pages with a handful of impressions a month; there is no one to persuade yet.

Leave a description alone when the page already earns at least what its position usually gets, or when Google shows a passage from the page that answers the query better than any summary would, which often happens with very specific questions. Rewriting there costs time and gains little.

Where it is worth it, the order is the one Search Console gives you: pages with many impressions and few clicks first. RankHive works through that list every week on a WordPress site, drafts a description for each page with the query and position beside it, and writes the one you approve into Yoast SEO, Rank Math or SEOPress.
