Web Quality factor
This factor is part of Web Quality — the weighted 0..100 score that sits above Web Standards. Its weight depends on what kind of site is being measured. Web Standards items take priority; this factor only enters the score once Web Standards passes.
- Base weight
- 0.0 applied to every site type unless overridden below
- Why this weight
- Tag manager presence — inventory only. GTM/Segment usage is a deployment choice, not a quality signal.
What this means for your business
A tag manager is what lets a marketer add or fix tracking without breaking your site. Its absence usually means tracking was bolted on once and never touched again.
Plain title: Whether your tracking is set up properly
What we measure
Whether the site uses a tag manager to load other scripts. Common ones: Google Tag Manager, Tealium, Segment.
How to improve your score
N/A — informational. If a tag manager is present, note that other detection results may be incomplete because tags load dynamically.
Facts
Implementation notes
Pattern-match GTM, Tealium, and Segment loader signatures.
Scoring
Scoring formulas are versioned with the methodology. The current method (v1.2.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
