How it works
The Title Length Checker scores your <title> tag against a 100-point rubric, measures its actual pixel width on desktop and mobile (not just character count), and optionally compares it to the top-10 Google titles currently ranking for your focus keyword.
Two modes:
- Paste (default): paste your title and (optional) meta description. Scoring runs entirely client-side, recomputing on every keystroke. No proxy fetch, no daily quota consumed.
- URL: paste a URL. We fetch the page through our proxy pool and extract the actual
<title>and<meta name="description">before scoring. Each URL audit consumes 1 unit from your daily page-audit quota (50 on the Free plan).
Pixel measurement: we use HTML5 Canvas measureText() against Arial Bold 20px for title-desktop (Google's SERP title font), Arial 16px for title-mobile, Arial 14px for description-desktop and -mobile. The pixel ruler bar updates as you type, color-coded green/amber/red against the per-viewport budget. A 60-character title might fit on desktop and be truncated on mobile; the rulers show this exactly.
The 10-rule scoring rubric: title character length (0-20 pts, sweet spot 30-60), title pixel width (0-25 pts, under 600 desktop), focus keyword in title (0-15 pts), focus keyword early in title (0-10 pts), description char length (0-15 pts, sweet spot 120-160), description pixel width (0-10 pts), focus keyword in description (0-10 pts), power-word bonus (+3), brand-in-title bonus (+2), ALL-CAPS penalty (-2). Capped at 100. A is 90+, B is 75-89, C is 60-74, D is 40-59, F is below 40.
SERP comparison (opt-in): click Fetch SERP titles after audit and we look up the top 10 Google organic results for your focus keyword at the selected location. Each result's title is pixel-measured and shown side-by-side with yours. Each SERP comparison consumes 1 unit from your daily SERP quota (10 on the Free plan).
AI rewrite (opt-in): click Rewrite my title and we return 3 alternative title variants, each constrained to under 600 pixels, each including the focus keyword. Each variant is pixel-measured server-side after generation. Each AI rewrite consumes 1 unit from your daily AI quota (50000 on the Free plan).
Live keyword data: when you supply a focus keyword we make a debounced API call and show real monthly volume, CPC, and competition score for the exact phrase below the input.
What each part of the audit shows
- Audited title block
- The exact title text and (URL mode) the audited URL we just scored. Helps you keep context when you re-open a share-link or check multiple URLs in sequence.
- Score (0-100) and letter grade
- Weighted roll-up of the 10 rubric rules. A is 90+, F is below 40.
- Score rubric breakdown
- Per-rule pass / fail / partial with the points contributed. Tells you exactly which rules pulled the score down.
- Desktop preview tile
- Mock rendering of how your title and description would appear in Google's desktop SERP. Pixel-accurate truncation simulation: anything past the 600-pixel title budget gets a real ellipsis at the cut point.
- Mobile preview tile
- Same as desktop but at mobile dimensions (480-pixel title budget). Mobile is the tighter constraint for almost every page.
- Pixel ruler bar
- Visual indicator of how much of the pixel budget your title or description uses. Green when in budget, amber close to the edge, red when over.
- SERP comparison panel (opt-in)
- Side-by-side table of the top-10 Google titles for your focus keyword, each with pixel width, character count, and keyword presence. Sortable.
- AI rewrite panel (opt-in)
- 3 alternative title variants generated by AI, each pixel-measured and grouped by length. Click any variant to copy.
- Live keyword data card
- Monthly volume, CPC, and competition score for your focus keyword. Helps confirm the keyword you're targeting actually has search demand.
Frequently asked questions
How long should a title tag be?
Aim for 50-60 characters. Google's SERP displays roughly 600 pixels of title on desktop (about 60 characters in average-width fonts at Arial Bold 20px) and roughly 480 pixels on mobile (about 35-40 characters depending on the letters). Titles that fit within both budgets render in full without an ellipsis on every device. This tool measures the actual pixel width per character (M and W are wide; i and l are narrow), not just the character count, so you see exactly what fits in each viewport.
What's the maximum length of a title tag?
There's no hard maximum in the HTML spec, but Google truncates the visible portion at around 600 pixels on desktop and 480 on mobile. Titles longer than that still get indexed in full, but anything past the cutoff renders as ... in the SERP. Long titles can also get rewritten entirely by Google (it pulls a passage from your page that better fits the budget). For both reasons, keeping titles under ~60 characters is the practical maximum.
Why does pixel width matter more than character count?
Google measures available space in pixels, not characters. "Mmmmmmmm" (8 wide M's) takes about 100 pixels at Arial Bold 20px. "iiiiiiii" (8 narrow i's) takes about 25 pixels. They're both 8 characters, but Google would truncate the M string at "Mmmmm..." while showing the full i string. Character counters can't see this; they'll tell you both titles are the same length. We measure actual pixel width using Canvas font metrics, the same way Google does, so the bar tells you the truth.
What does the score measure?
The 100-point Title Score rolls up 10 weighted rubric rules: title character length (sweet spot 30-60), title pixel width (under 600 desktop), focus keyword present in title, focus keyword early in title, description character length (sweet spot 120-160), description pixel width (under 920 desktop), focus keyword in description, power word bonus, brand in title bonus, and an ALL-CAPS penalty. A is 90+, B is 75-89, C is 60-74, D is 40-59, F is below 40. The rubric runs both server-side (source of truth) and client-side (for live recompute as you type in paste mode).
What does the SERP comparison feature do?
When you supply a focus keyword and click Fetch SERP titles, we look up the top 10 Google organic results for that keyword at your selected location, pixel-measure each one's title, and render a side-by-side comparison with your title. You see exactly how your title stacks up in length, keyword usage, and structure against the pages that are already ranking. This is the killer differentiator: instead of guessing "is my title good?" you see the actual current competition. Each SERP comparison consumes 1 unit from your daily SERP quota (10 on the Free plan).
How does the AI rewrite feature work?
Click Rewrite my title and we send your current title, focus keyword, and constraints (under 600 pixels, include the keyword) to a large language model that returns 3 alternative title variants. Each variant is pixel-measured server-side after generation, so you see exactly how each one would fit. Click any variant to copy it. Each AI rewrite call consumes 1 unit from your daily AI quota (50000 on the Free plan).
What's the difference between Paste mode and URL mode?
- Paste mode (default): paste your title and (optional) meta description directly. Scoring runs client-side as you type, with live pixel rulers. No proxy fetch, no daily quota consumed. Best for tuning a draft.
- URL mode: paste a URL. We fetch the page through our proxy pool, extract the actual
<title>and<meta name="description">, and score them. Best for auditing what's actually live. Each URL audit consumes 1 unit from your daily page-audit quota.
Will Google use my title exactly as I wrote it?
Often yes, sometimes no. Google has stated that it rewrites roughly 60-70% of titles on the SERP when it judges that an alternative phrasing from your page body better matches the query. This is normal. To improve your odds of Google using your title as-is: keep it under 600 pixels (so Google doesn't need to compress it), include the focus keyword early, match the page intent precisely, and avoid generic phrasings the algorithm can't verify. Your title still serves as the strong default and as input to AI Overviews and social previews even when Google chooses a different SERP snippet.
