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.
Semantic Coherence
Homepage promise vs. Sub-page reality.

There is zero semantic drift between the homepage signal and sub-page content. The homepage H1 Information and articles about our Puzzles is immediately validated by technical blog posts that serve as a database for collectors. The transition from a retail store to a retired archive is communicated consistently across every page analyzed.
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.
🏗️ Semantic Structure — heading hierarchy & page identity (the promise the page makes)

[H3] So, who is Mr Puzzle himself? Brian Young has been making puzzles at Mr Puzzle since 1992. Mr Puzzle started out selling only our own brand of puzzles way before internet shopping was thought of. We sold our puzzles at a craft market at Southbank Parklands in Brisbane. From 1998 when we launched our first website we knew it was going to be a great way to connect to many international customers who were visiting Australia and found us at Southbank and wanted to buy more puzzles. Over the years we started combining selling our own product with puzzles bought in from other suppliers; most of whom do not sell via any other outlet in Australia. Brian himself is well known to collectors around the world for his amazing Limited Edition puzzles, very hard burr puzzles, and more recently his sequential discovery puzzles. His last Limited Edition SMS Box (series now Sold Out) is generally acknowledged as his hardest puzzle ever and there are many collectors out there who’ve never been able to solve it. Brian is also a puzzle collector and puzzle solver. He enjoys playing with puzzles and sourcing puzzle designs. As Mr Puzzle has grown Sue Young has taken over the Administration. We’re a small team but that just makes our service more personalised. [IMG: Brian and his puzzle collection] [H3] And what about Sue & Brian as the partners who own Mr Puzzle? [IMG: Sue and Brian Young Mr Puzzle] Sue & Brian having fun at the Melbourne Toy Fair with Mel from UGames You’ll get some insights into who are are from this discussion with Mel from UGames at the Melbourne Toy Fair in March 2020.
