About

A listing title that ranks requires more than keywords stuffed into 60 characters. Search engines evaluate keyword placement weight - a target phrase at position 0 scores higher than one buried at position 8. They measure lexical diversity, the ratio of unique tokens to total tokens (U รท N), and penalize titles that exceed the pixel-width truncation threshold (approximately 580px on desktop SERPs). Getting this wrong means your listing appears with an ellipsis - losing 15 - 30% click-through rate compared to fully visible titles. This tool calculates keyword density as d = (k รท N) ร— 100, scores front-loading position, detects power words from a curated dictionary, and flags stop-word bloat.

The scoring model weights seven distinct factors and outputs a composite score from 0 to 100. It approximates SERP pixel width using average character widths for Arial at 20px - the standard Google rendering font. Limitation: actual pixel width varies by character composition; this tool uses weighted averages, not per-glyph measurement. Pro Tip: place your primary keyword within the first 3 words and keep total character count between 50 and 60 for optimal visibility.

Formulas

The composite title score S is computed as a weighted sum of seven normalized sub-scores, each bounded to the range [0, 1]:

S = 7โˆ‘i=1 wi โ‹… si

where wi is the weight for factor i and si is the normalized score for that factor. The keyword density sub-score uses:

d = kN ร— 100

where k = number of keyword occurrences, N = total word count. The uniqueness ratio is calculated as:

Ru = UN

where U = count of unique words (case-insensitive, stop words excluded), N = total meaningful words. SERP pixel width is approximated via:

Wpx = nโˆ‘j=1 w(cj)

where w(cj) is the estimated pixel width of character cj in Arial 20px. Uppercase characters use a 1.2ร— multiplier. The keyword position score decays linearly: spos = max(0, 1 โˆ’ p รท 10), where p is the zero-indexed word position of the first keyword match.

Frequently Asked Questions

Search engines assign diminishing weight to words as they appear later in a title tag. A keyword at word position 0 receives the highest relevance signal. Studies by Moz and Ahrefs show titles with the primary keyword in the first 3 words correlate with 20% higher CTR. The tool scores position using a linear decay: spos &equals; max(0, 1 โˆ’ p รท 10). A keyword at position 5 scores 0.5; at position 10 or beyond, it scores 0.
The tool estimates pixel width using averaged character widths for Arial at 20px, which is Google's default SERP title font. Narrow characters like "i" and "l" use ~5px, while wide characters like "W" and "M" use ~14px. Accuracy is within ยฑ5% for Latin scripts. CJK characters, emoji, and special Unicode glyphs are estimated at 12px average width and may deviate further. Google's actual rendering depends on device, OS font rendering, and potential title rewriting.
For standard listing titles (50 - 60 characters), a keyword density above 4.0% typically indicates stuffing in organic search. In a 10-word title, repeating a single keyword 3 times yields 30% density - obvious stuffing. The ideal range is 1.5 - 3.0% for most platforms. Amazon tolerates slightly higher densities due to longer allowed titles (200 chars). The tool flags anything above 4.0% with a warning.
Yes. Conductor research shows titles containing numbers receive 36% more clicks than those without. Numbers create specificity and set expectations (e.g., "7 Tips" vs 'Tips'). Odd numbers slightly outperform even numbers in engagement studies. The tool awards 10% weight to number presence. Years (e.g., 2024) and specific quantities both qualify.
The uniqueness ratio Ru &equals; U รท N measures lexical diversity. Stop words (the, a, in, of, for) are excluded from both U and N in this calculation to avoid penalizing grammatically correct titles. A ratio below 0.5 indicates excessive repetition of meaningful words. A ratio of 1.0 means every meaningful word is unique. The tool targets โ‰ฅ 0.8 as optimal.
Separator characters (| - : -) are common in listing titles for brand separation. Google may rewrite titles that use uncommon separators. The tool counts these as regular characters in length and pixel width calculations. Pipes consume approximately 6px width. The tool does not penalize separators but recommends limiting to 1 separator to preserve keyword space. Multiple separators fragment the title and dilute keyword proximity signals.
