What is the Ideal Headline Length?
Ideal headline length is 6–9 words and 50–60 characters. Seeklyn scores the length sub-score by averaging a word-count score and a character-count score: both peak at 100 in their ideal ranges and decay toward 0 at the outer bounds (4 words / 20 chars minimum; 12 words / 70 chars maximum).
Seeklyn shows live word-count and character-count meters as you type a headline in /dashboard/headline — the marker moves across the scale in real time.
What is the ideal headline word count?
6–9 words is the ideal word-count range for a headline. Seeklyn scores a 6-word headline and a 9-word headline equally at 100. Outside that range, the score decays: within the 5–12 word buffer zone it loses 10 points per word beyond the ideal range, floored at 40. Beyond 12 words (or below 5), the score decays more steeply and can reach 0.
The ideal of 6 words aligns with CoSchedule's headline research showing that 6-word headlines generate the highest average click-through rate. Longer headlines can still perform well — a 9-word headline scores 100 — but beyond 12 words the score reflects the growing risk of truncation and reader fatigue.
What is the ideal headline character count?
50–60 characters is the ideal character-count range. Seeklyn scores any headline in that band at 100. For headlines between 30 and 50 characters, the score rises linearly from 40 (at 30 chars) to 100 (at 50 chars). For headlines between 60 and 65 characters, the score falls linearly from 100 (at 60) to 40 (at 65). Beyond those outer limits (below 30 or above 65 characters), the score decays further and can reach 0.
The 50–60 character range is also the Google SERP display window. Titles beyond ~60 characters are commonly truncated in search results with an ellipsis, though Google may also rewrite the displayed title — see the Google Title Rewrite page. A headline under 20 characters often lacks enough context to communicate a clear promise.
How is the length sub-score calculated?
The length sub-score is the average of the word-count score and the character-count score, rounded to the nearest integer. This means a headline that is perfect in words (6–9) but too long in characters (65+) will score lower than one that hits both targets simultaneously. The dual-axis approach catches headlines that are grammatically short but padded with long words.
| Dimension | Ideal (score 100) | Min / Max (score 0) | Gauge meter ideal |
|---|---|---|---|
| Words | 6–9 | ≤4 / ≥12 | 6 words |
| Characters | 50–60 | ≤20 / ≥70 | 55 characters |
Why does character count matter for AEO?
Headlines longer than 60 characters risk truncation in Google Search results and are flagged as a potential Google title rewrite. AI answer engines like Google AI Overviews and Perplexity also use the title tag as a retrieval signal; an overly long title can dilute the keyword signal and reduce retrievability. Keeping the character count within 50–60 aligns the headline for both classic CTR and AEO.
Frequently asked questions
Does Seeklyn count spaces in the character count?
Yes. Seeklyn counts the full character count of the trimmed title string, including spaces and punctuation. The 50–60 character ideal is for the complete visible title.
Is a 5-word headline always worse than a 6-word headline?
In Seeklyn's scoring model, a 5-word headline scores lower than a 6-word headline because it falls just outside the 6–9 ideal range. In practice the difference is small — a 5-word headline still scores above 40 — but a 6-word headline is the documented optimal for click-through.
What if my brand name adds 20 characters to the title?
Seeklyn's Safer Title Variant feature detects titles over 60 characters and suggests a shorter version by removing a trailing brand suffix or trimming whole words from the end while preserving the keyword. This is the practical solution for brand-appended titles.
