What Is an A/B Title Test?
An A/B title test compares two or more page titles to predict which one will earn the most clicks in Google search results. Instead of running expensive live tests on real traffic, this tool scores each title against documented CTR factors — keyword placement, length, power words, and intent alignment — and picks the strongest version.
You enter up to 5 candidate titles, optionally a focus keyword and search intent. Each title gets a 0–100 CTR score, an SEO score, character count, pixel width, and a live Google SERP preview. The winner is highlighted with a clear reason.
The Six Scoring Categories
- Keyword Match (20 pts) — keyword presence, position (earlier is better), and stuffing penalty.
- CTR Optimization (20 pts) — power words (free, best, easy), numbers, brackets, year, question/exclamation marks.
- Length Optimization (15 pts) — character count + pixel width vs. Google's ~580px desktop limit.
- Readability (15 pts) — word count (6–12 ideal), word length, ALL-CAPS penalty.
- Intent Match (15 pts) — words that signal the search intent you selected (informational / commercial / transactional / navigational).
- Uniqueness (15 pts) — how distinct each title is from your other tested titles (Jaccard similarity on words).
Why Pixel Width Matters
Google truncates titles by pixel width, not character count. The desktop SERP limit is roughly 580 pixels. A title with wide capital letters can hit the limit at 50 characters, while one with narrow lowercase letters might fit 65. This tool measures both and shows you exactly when truncation kicks in.
