Meta titles and descriptions, written where missing
The pair gets shown either way. The title becomes the line somebody clicks; the description becomes the sentence under it, when the engine chooses to use one. Where neither was written, both are still assembled by something that has never read your brief.
What each one is read for
The title is a name, not a summary. <title> is the string a result list shows, the label a browser tab carries, and the text a bookmark keeps. It is read by people scanning twenty of them at once, which is why the specific words at the front matter more than the ones at the end.
<meta name="description"> is not a ranking field, and has not been one for a long time. It is an argument for the click, and the engine is free to ignore it and assemble its own line from the page instead. That freedom is often mistaken for the tag being pointless. It is not: a page with nothing to offer gives the engine nothing to prefer.
What happens where neither is declared
The engine writes both anyway. It has to show something, so it takes the first heading it trusts and a passage that looks relevant to the query. The result is usually adequate and occasionally wrong in a way nobody notices until somebody searches for the page by name.
Enrichment fills the gap from what the page actually says. Where a title exists, it stays; where a description was never written, one is written from the page's own content, not invented around it.
What the model is given
Two inputs, and the difference between them is the whole design.
The first is the page itself. A description is written from what the page actually says, which is why the result reads like a summary of your content rather than a summary of your industry. Nothing is pulled from a competitor, a directory or a general idea of what a business like yours probably does.
The second is your brand profile: the site's name, the social handle, the postfix that belongs on a title. Those are facts you set once, and they are copied, never worked out. It matters which side of the line each input sits on. The parts of a tag that have to be exact are the parts nobody is generating, and the parts being generated are the ones where wording is a matter of judgement rather than fact.
A short account of what the site does and how its copy should sound can steer the wording. It is read while the tag is written and never published on the page.
When the page itself says little
Generation describes what is there. A page with three sentences on it gives a generated description three sentences to work from, and the result will be as thin as its source.
This is worth saying plainly because the opposite promise is common in the category. Nothing here invents a benefit the page does not claim, a statistic it does not carry or an audience it never named. Where a page is thin, the honest outcome is a thin description, and the fix is on the page rather than in its head.
The same applies to a page that says several unrelated things. A description has room for one idea. Where the page holds four, the generated line picks the one the page leads with, which is usually the right choice and occasionally a sign that the page needs splitting.
What it does not touch
A title you wrote is kept exactly as it stands, including the ones you regret: the absent gets written, and the present stays yours.
The same brand profile feeds the Open Graph set, which is why a page filled in both places does not contradict itself. The brand postfix is the one place the two meet. A generated title can end with the site's name because the brand profile says so. That is a fact you set, applied verbatim, not a rewrite of anything.
The two are not the same job
They sit next to each other in the head and are usually discussed as a pair, but generating them is not the same problem twice.
A title is close to a fact. It names the page, it has to match what the page is called elsewhere on the site, and it carries the postfix you set. There is little room for interpretation, which is why so much of it comes from the brand profile rather than from the model.
A description is closer to an argument. It has to say why this page and not another, in one sentence, to somebody who has not arrived yet. That is a matter of wording rather than of fact, and it is where a generated line earns its place: not because it beats a written one, but because the alternative on a page that has none is whatever the engine improvises.
FAQ
Will a generated description outrank a written one?
Neither one ranks. A description is not a ranking field and has not been one for a long time. What it influences is whether somebody chooses your result once they can already see it, which is worth having for its own sake. Treating the tag as a lever on position is the mistake; treating it as the sentence that argues for the click is not.
What if the engine rewrites it anyway?
It often will, and that is normal behaviour, not a fault. Engines substitute their own line when they judge the declared one a poor match for the query. Generic or duplicated text makes substitution more likely, and specific text makes it less so. A page with no description gives the engine nothing to prefer, so substitution there is not merely likely but the default.
Does the postfix count as changing my title?
No. It is appended to titles that are generated here, never to one you wrote yourself. The postfix is a fact from your brand profile and not an edit, and it is applied at the point a title is written from nothing. A title you wrote keeps whatever ending you gave it, including none.
Can a generated description be wrong about the page?
It can be thin, and it can pick the wrong idea from a page that holds several. What it does not do is state something the page never claimed. The source is your own content, so an inaccuracy in the description is almost always an inaccuracy already sitting in the copy above it.
What happens when I edit the page?
The description was written from the page as it stood. Substantial edits make it less accurate over time, in the same way a hand-written one drifts after a rewrite nobody re-checked. The tag stays under your control: fill in your own, and the generated line steps aside for good.
