Semantic Coherence: The Oatmeal – Signal Evidence & AI Readability

Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

A significant semantic drift is present due to technical failure rather than marketing spin. While the homepage H1 and navigation promise specific content like Comics and Blog, every targeted sub-page (naked_mole_rats, dog_paradox_trailer, ai_art) returns a [H1] 404 – Not Found. This creates a total disconnect between the signal (content titles) and substance (dead pages).

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

[H2] Hi. My name is Matthew Inman, and I'm a cartoonist.

I've been publishing comics on this website since 2009.
Every few years, I compile these comics into books, such as
How to tell if your cat is plotting to kill you.
I also make card games, such as Exploding Kittens and Horrible Therapist.

My Netflix series is now streaming.
