Meta description generator

What this Gemini meta description generator fits into

This is the last field you fill before a page ships, and the one most likely to get the site tagline pasted into it instead. Paste the page's actual text here and you get a snippet-length description of it: written for someone scanning a results page, not for someone who already arrived.

It is a server route. Your text goes to our AI server, the allowance is 5 runs per rolling 24 hours, and each run takes 1 to 12,000 characters of source text. It accepts text and not a URL, because nothing in this route fetches a page. Paste the content, not the address.

Set your expectations first

Google rewrites meta descriptions, and that changes the job

Before you build a process around this, know what the output actually is. The description you write is a proposal. Google substitutes its own extract when it judges yours weak, off topic, or a worse answer to the specific query than something else on the page.

So the goal is not a description that gets displayed every time, because that is not on offer from any tool. The goal is a description specific enough that substituting it would be a downgrade. That is a writing target you can actually aim at, and it is why a generated draft still needs your pass over it.

The workflow

How to generate a meta description in three steps

Generate, count, front-load. The count is not optional and neither is the front-load.

Step 1: Paste the page's real text, not a description of the topic. A description generated from the actual content is the one least likely to be replaced.
Step 2: Run it, then count characters immediately. Under 160 is the working target, and anything over it gets cut from the end rather than rewritten from the start.
Step 3: Read only the first half and ask whether it says what the page is. That is what a phone shows, so if the first half is a wind-up, move the point forward.

The number to work to

How long should a meta description be?

The published guidance conflicts. One SEO tool page we checked says 150 to 160 characters. Another says 120 to 155. Neither sources its number, and both are approximating the same thing, which is where a desktop result truncates.

The reason they cannot agree is that there is no character limit. Results truncate on available width, and width varies by device, so every character figure is a proxy for a pixel measurement. For a working process: under 160, with the first half carrying the meaning. Our own build enforces a 160-character ceiling on every description across this network, so that is the number this page works to rather than a borrowed one.

Straight answer

Do meta descriptions help SEO rankings?

No. The meta description is not a ranking factor, and no amount of rewriting it will move a position. If a process is justified on the grounds that better descriptions rank better, the process is justified on something false.

The honest justification is click-through. Same position, same query, two results side by side, and the one whose description answers the question gets opened. That is a smaller claim than the usual one and it is the one that holds up.

Doing this across a site

Writing unique meta descriptions at scale

The audit is fast. The writing is not. Here is where the time actually goes.

Find the duplicates first: Templates fill the field from a category name and CMSs fall back to the site tagline. One description on four hundred pages is the usual finding, and it is the highest-value fix.
Prioritise by position: Pages already ranking on page one gain the most from a better description, because they have impressions to convert. A page nobody sees gains nothing from a better snippet.
One run per page: This route has no batch mode and no API, and the allowance is 5 runs per rolling 24 hours. A large site is a multi-day job here, and pretending otherwise would waste your time.
Paste specifics, not templates: If you paste the category boilerplate you get a description that fits every page in the category, which reproduces the exact problem you started with.

The checklist

What to check before you paste the description in

Four checks, run in this order, each taking a few seconds.

First words say what it is: Not what the page explores or discusses. What it is. This is the part that survives truncation everywhere.
The query's words appear: Present, not stacked. A scanning reader matches against what they typed, and matched words are where the eye stops.
One specific the others lack: A number, a limit, a constraint. Specifics outperform adjectives on a results page because every competing result has the adjectives.
No promise the page does not keep: An oversold description buys a visit and a bounce. It also raises the odds the search engine replaces it with its own extract.

Who uses it

Who runs a meta description generator regularly

Three situations where the field is a bottleneck rather than a detail.

Teams shipping pages weekly: The description is the field filled last and worst, and a generated starting point beats whatever the template would have inserted.
Anyone mid-audit: Identifying missing and duplicate descriptions takes minutes. Replacing them is the part that stalls, and it is the part this route helps with.
Writers who drafted in Gemini: The article exists and the snippet does not. They are genuinely different pieces of writing with different readers.

FAQ

Everything answered. Questions about generating meta descriptions

How do I generate a meta description?

Paste the page's text above and run it, then count the characters and check that the first half stands alone.

Is the meta description generator free?

Yes, 5 runs in any rolling 24 hours, with no account to create.

How long should a meta description be?

Under 160 characters as a working target. Published advice spans 120 to 160 because results truncate on width, not on character count.

Why do sources disagree about the length?

Because the real constraint is pixel width, which differs between desktop and mobile, so every character figure is an approximation.

Why does Google show a description I did not write?

It substitutes its own extract when it judges yours weak, off topic, or less useful for the query than something else on the page.

Is it still worth writing one?

Yes. The aim is a description specific enough that replacing it would be a downgrade, which is a target you can actually write to.

Do meta descriptions improve rankings?

No. They are not a ranking factor. They affect the click-through on the position you already have.

Can I paste a URL?

No. This route takes text only, because nothing here fetches a page. Paste the content itself.

How much text can I paste per run?

Between 1 and 12,000 characters of source content.

Is my text sent to a server?

Yes. This is a server route, so avoid pasting unpublished material you need to keep private.

Is there a bulk mode for a whole site?

No. No batch mode, no API, and 5 runs per rolling 24 hours, so a large site is a multi-day job here.

Which pages should I fix first?

The ones already ranking on page one. They have impressions to convert, so a better description pays back immediately.

Does every page need a unique description?

Yes. A description covering forty pages helps a reader pick none of them and invites the search engine to write its own.

What belongs in the first few words?

What the page is. Not what it covers or explores. That opening fragment is what a phone displays.

Should the keyword be in there?

The words someone would type should be present, because that is what a scanning eye matches. Do not stack them.

Does this write title tags as well?

No. Title tags have their own route on this network and a much tighter character budget.

Does it work for product pages?

Yes, provided you paste the specific product details. Pasting category boilerplate reproduces the duplicate-description problem.

Why is 160 the number used here?

Because our own build enforces a 160-character ceiling on every page description across this network. It is a limit we apply to ourselves.

What if the output is too long?

Cut from the end. If it was written correctly the information worth keeping is already at the front.

Does it work on a phone?

Yes. Paste into the box in a mobile browser and run it the same way.

Is this affiliated with Google?

No. This is an independent page, not made by, endorsed by or connected to Google or Gemini.
