SERP Snippet Preview
Shown as the breadcrumb line above the title.
What is a SERP snippet?
A SERP snippet is the block Google shows for your page in search results: the site name and breadcrumb, the clickable title tag, and the meta description beneath it. It is the entire pitch you get before someone decides whether to click you or the result below you.
This preview renders that block at Google's own font sizes and column widths, on desktop and mobile, so you can see where your copy gets cut before you publish it rather than after.
How long should a title tag be?
Google truncates on pixel width, not character count, so there is no single correct number. A desktop title fits in roughly 600 pixels, which lands near 55–60 characters for ordinary mixed-case text.
Wide letters spend that budget faster. Sixty characters of Illinois litigation limits and sixty characters of WOMEN'S WATERPROOF WALKING BOOTS occupy wildly different widths, and only one of them survives. This is why every “keep it under 60 characters” rule is an approximation - and why the meter above counts pixels instead.
How long should a meta description be?
Around 155–160 characters is the usual advice, and again the real limit is space. Google shows roughly two lines on desktop and three on mobile, so mobile often displays more description than desktop despite the narrower column.
Front-load the point. Truncation always eats the tail, so a description that opens with what the visitor gets loses nothing important when it is cut.
How to preview your Google snippet
- Paste your title tag, page URL and meta description into the fields above.
- Watch the meters: they turn amber the moment your text exceeds the space available.
- Switch between Desktop and Mobile - the column narrows, the title gains a second line, and the description gains a third.
- Rewrite until nothing important sits past the cut.
Nothing is uploaded. The whole tool runs in your browser, so unpublished copy stays on your machine.
Where to put your keywords
At the front of both fields. A title that reads Bulk Domain Age Checker - Free, No Sign-Up | KWScanner loses nothing important when truncated, while KWScanner | The Best SEO Tools For Agencies And In-House Teams - Domain Age loses the only words describing the page.
- Title: the specific promise of this page, then the qualifier, then the brand. Around 600 pixels on desktop.
- Description: what the visitor gets and why it beats the other nine results. Two lines desktop, three mobile.
- URL: short and readable. Google renders a breadcrumb rather than the raw path, so deep folder structures show up as clutter.
Why does Google rewrite my title and description?
Because it thinks it can answer the query better than your copy did. Google rewrites titles on a large share of results, and rewrites descriptions more often still - usually swapping in a passage from the page that matches the search more closely.
That is not a reason to skip writing them. It is a reason to write ones Google has no motive to replace. Vague, duplicated and keyword-stuffed titles get overridden most; clear, specific, query-relevant ones survive.
Do meta descriptions affect rankings?
No. Google has confirmed the meta description is not a ranking factor and has not been for many years. What it affects is click-through rate, which is a different and equally worthwhile job - a page that ranks fifth and gets clicked beats one that ranks third and does not.
Write the title after the keyword research, not before
The phrasing that wins a click is usually the phrasing people actually typed. Pull the demand data first - which variant gets searched, what advertisers pay for it, whether it is seasonal - and let the winning phrase set the title.
Guessing at the phrase and then checking its pixel width is optimising the wrong end of the problem. KWScanner handles the first end: volume, CPC and competition for up to 3,000 keywords in a run. Then come back here and make the winner fit.
Common questions
How long should a title tag be?
Google truncates on pixel width, not character count, so there is no single correct number. As a rule of thumb a desktop title fits in about 600 pixels, which lands near 55-60 characters for typical mixed-case text. Wide letters eat that budget faster: a title of capital Ms runs out long before one of lowercase i's.
How long should a meta description be?
Around 155-160 characters is the usual advice, and again the real limit is space rather than characters. Google shows roughly two lines on desktop and three on mobile. Front-load the point so a cut tail costs you nothing.
Does a meta description affect rankings?
Not directly. Google has confirmed meta descriptions are not a ranking factor. They affect click-through rate, which is worth optimising on its own terms - a page that ranks fifth and gets clicked beats one that ranks third and does not.
Why does Google rewrite my title and description?
Because it thinks it can serve the query better. Google rewrites titles for a majority of results and rewrites descriptions even more often, usually pulling a passage from the page that matches the query. A clear, query-relevant title is the best defence - vague or keyword-stuffed ones get replaced most.
Is this preview exact?
It is a close approximation, not a promise. It renders your text at Google's font sizes and container widths and clips it where Google would. What it cannot predict is whether Google will rewrite your copy, add a date, show sitelinks, or pick a different breadcrumb.
Does the preview send my text anywhere?
No. Everything runs in your browser. Nothing is uploaded, logged or stored.
Pick the phrase before you fit the pixels
A perfectly sized title around the wrong keyword is still the wrong title. KWScanner gives you volume, CPC and competition for up to 3,000 keywords at a time, priced per keyword rather than per seat.
