Free SERP Simulator
Type a title and a meta description and see exactly how they will look in Google, cut where Google would cut them. It measures in pixels rather than characters, which is the only measurement that matches what actually happens — and it switches between desktop and mobile, because a title that fits one often does not fit the other.
No description entered — Google will generate one from the page.
Everything above runs in your browser. Nothing you type is sent anywhere.

Why pixels and not characters
Every guide gives a character count and every character count is wrong, because letters are not the same width.
In the font Google uses, a lowercase i is about four pixels wide and a capital W is about eighteen. So a sixty-character title made of narrow letters fits comfortably, and a fifty-character title full of capitals and wide letters gets cut. Two titles with identical character counts can behave completely differently, which is why a counter feels reliable and quietly is not.
This tool renders your text in the actual font at the actual size and measures the result. The character count is still shown, because people expect it, but it is the smaller number on the page for a reason — the pixel meter is the one that determines whether your last three words survive.
The budgets are approximate. Google adjusts them, and they shift slightly depending on the query and the type of result. Treat the meter as a well-calibrated guide rather than a guarantee, and leave yourself a little headroom rather than writing to the exact edge.
Google rewrites titles, and here is when
A large share of titles shown in results are not the ones the site wrote. Google substitutes its own when it judges yours unhelpful for the query, and the patterns behind that are consistent enough to design around.
It rewrites when the title is too long and the useful part is being cut off. It rewrites when the title is stuffed with repeated keywords. It rewrites when the title is generic — Home, Products, Untitled — and the page is plainly about something specific. It rewrites when the title is identical across many pages on a site. And it rewrites when the H1 or the on-page heading describes the page more accurately than the title does.
The way to keep your own title is to make it the best available description of the page: specific, front-loaded, matching what is actually on the page, and short enough that none of it gets cut. Note that Google may still swap in your brand name or trim it, and that is normal rather than a fault.
Writing a title that earns the click
Put the important words first. Titles are cut from the right, and they are scanned from the left. Whatever matters most should be in the opening third.
Match the phrasing to the query rather than to internal vocabulary. A page a company calls Solutions Overview is, to the person searching, a page about a specific product. Titles written in the language of the organisation are the most common reason Google decides it can write a better one.
Say what makes it different in the second half. Free, the year, a number, the format — whatever is genuinely true and separates this result from the four around it. This is where the clicks come from, because the first half establishes relevance and the second half establishes the reason to choose you.
Keep the brand at the end, or leave it out. Front-loading a brand name spends the most valuable pixels on the word least likely to be searched, unless the brand is the reason people are clicking.
Once the title holds up, run the description through the meta tag generator to keep the two consistent.
The meta description does not affect rankings
It has not been a ranking factor for many years and Google has confirmed this repeatedly. Writing one will not move a page up.
What it does affect is whether anyone clicks, which affects everything downstream. A result that describes exactly what the page delivers wins clicks from results that describe a category.
Google also replaces descriptions frequently — more often than it replaces titles — usually by pulling a passage from the page that better matches the specific query. That is not a failure. A description written for one query cannot serve all of them, and Google substituting a more relevant passage is generally doing the reader a favour.
Write one anyway. When Google keeps it, it is the best possible version. When Google replaces it, you have lost nothing. Leaving it blank means the machine always chooses.
Desktop and mobile are different budgets
A mobile result is narrower and uses a different font size, so the pixel budget is meaningfully smaller for both the title and the description.
In practice this means a title that fits perfectly on desktop can lose its last few words on a phone. Since most search traffic is mobile for the majority of sites, the mobile view is usually the one to write to, and the desktop view is the one that then has room to spare.
The toggle above switches between them. Write for the narrower budget, check the wider one, and you will never be surprised.
Common mistakes
Writing to a character count. The number that decides is pixel width, and the two disagree constantly.
Duplicating titles across pages. Google treats near-identical titles as a signal that the pages are near-identical, and rewrites them.
Filling the title with keywords. It reads badly to a person and reliably triggers a rewrite — check for it with the keyword density checker.
Writing the description as a summary of the company rather than the page. The description competes against four other descriptions on one screen; a paragraph about the organisation loses to a sentence about the answer.
Using emoji or unusual characters to stand out. Most are stripped, some render inconsistently, and the ones that survive frequently look like spam.
Checking desktop only. The narrower budget is the one most of your audience sees.
If titles across a whole template need rewriting rather than one page, that is an on-page SEO job rather than a preview tool. The simulator stays free.
Frequently asked questions
How long should a title tag be?
Think in width rather than letters — roughly 580 pixels on desktop and about 490 on a phone, which lands near 60 and 50 characters respectively. The conversion is unreliable because letter widths differ so much, so use the meter above and leave a small margin instead of writing right up to the boundary.
How long should a meta description be?
Around 920 pixels on desktop and 680 on mobile, which works out at roughly 155 and 115 characters. Front-load the part that matters, because the mobile cut arrives much sooner than most people expect.
Why does Google show a different title than the one I wrote?
Because it decided its version served the query better. That usually happens when yours is over-long, repetitive, too generic, duplicated across the site, or less accurate than the heading on the page itself. Fixing the underlying weakness is what restores your version; there is no setting to force it.
Does the meta description affect rankings?
No. Google has stated this plainly and repeatedly. Its value is entirely in persuading someone to choose your result over the others on screen, which matters a great deal without being a ranking input.
Why does Google rewrite my meta description?
Typically because it found a passage on the page that answered the specific search more directly. A single description cannot suit every query a page ranks for, so substitution is normal and often an improvement. Write one regardless — when it is kept, it is the strongest version available.
Why measure in pixels instead of characters?
Because characters are not equal widths. In Google’s font a lowercase l occupies a fraction of the space a capital M does, so two titles of identical length can produce entirely different results — one intact, one truncated. Measuring the rendered width removes the guesswork.
What happens if my title is too long?
It gets cut from the right and an ellipsis is appended, so the closing words disappear. If the distinguishing part of your title lives at the end, that is precisely what is lost. Google may also treat over-length as a reason to write its own replacement.
Should I include my brand name in the title?
Put it at the end if you include it at all, and consider dropping it on pages where the searcher is looking for a topic rather than for you. Leading with a brand spends the most valuable space on the word least likely to have been typed — worthwhile only when the brand is itself the draw.
Do emojis work in search results?
Occasionally, and unpredictably. Google removes most of them from titles and descriptions, rendering varies between devices, and the survivors often read as spam. Not something to build a strategy on.
Is this the same as Google’s own preview?
Google does not publish one. Its Rich Results Test examines structured data rather than how a snippet will look, so a simulator like this is the closest available approximation — calibrated against live results and honest about the fact that the boundaries shift. For checking the structured data itself rather than the visual snippet, there is also our schema markup validator.
