Why snippets matter
Your snippet is your ad, in Google and in AI answers
Ranking gets you on the page. The title and description decide whether anyone clicks. A title that is cut off mid word, or a description that says nothing about the searcher's problem, loses clicks to results below you. AI assistants add a second surface: they quote one clear sentence and show your domain as a source. If your opening sentence is vague, you are less likely to be the one quoted.
Keyword first
Put the phrase people search near the start of the title. It is the part that survives trimming and gets bolded.
Benefit in the description
Say what the reader gets in one or two sentences. Treat it as ad copy, not a summary of the page.
Quotable opening
Start the page with a short, factual definition or answer. Assistants lift sentences that stand on their own.
Brand at the end
End the title with your brand after a separator, so it builds recognition without pushing out the keyword.
One page, one intent
Each title should promise one thing. Titles that try to cover everything read as vague in both Google and AI answers.
Check on mobile
Most searches happen on phones, where descriptions are shorter. Make sure the first half of yours carries the message.

FAQ
Questions about snippets
Why measure pixels instead of characters?
Google cuts titles by width, not by character count. A title full of wide letters like W and M is cut sooner than one with narrow letters like i and l. The simulator measures the real width in the font Google uses, so what you see is close to what searchers see.
How long should a title tag be?
Aim for under about 600 pixels on desktop, which is usually 50 to 60 characters. Put the main keyword near the start and your brand at the end, so the important part survives if Google trims it.
How long should a meta description be?
Around 920 pixels on desktop and about 680 on mobile, roughly 120 to 158 characters. Google sometimes rewrites descriptions, but a clear one that matches the search still wins clicks more often.
What is the AI snippet preview?
Assistants like ChatGPT, Perplexity and Google's AI answers often quote a single clear sentence and link your page as a source. The preview shows your first sentence as a quoted answer, so you can check it stands on its own.
Can I load an existing page?
Yes. Paste the page address and press Load page. We fetch the live title, meta description and first paragraph so you can edit from there.
Is it free?
Yes. The simulator runs in your browser with no account, and nothing you type is saved.
