Information Density: Jekyll – Signal Evidence & AI Readability

Jekyll

(https://jekyllrb.com) 📸 Data Snapshot: May 27, 2026
Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.
30 Impact Weight: 30 / 100
100% Reputation

The information density is exceptionally high. Headings such as Prerequisites, Instructions, and Themes are strictly functional, leading directly to specific technical data and code. Between headings, the text consists almost entirely of specific claims, technical protocols, and command-line instructions, with virtually zero marketing fluff or power word saturation.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

[H1] Quickstart
Jekyll is a static site generator. It takes text written in your
favorite markup language and uses layouts to create a static website. You can
tweak the site’s look and feel, URLs, the data displayed on the page, and more.
[H2] Prerequisites
Jekyll requires the following:
Ruby version 2.7.0 or higher
RubyGems
GCC and Make
See Requirements for guides and details.
[H2] Instructions
Install all prerequisites.
Install the jekyll and bundler gems.
gem install jekyll bundler

Create a new Jekyll site at ./myblog.
jekyll new myblog

Change into your new directory.
cd myblog

Build the site and make it available on a local server.
bundle exec jekyll serve

Browse to http://localhost:4000
If you are using Ruby version 3.0.0 or higher, step 5 may fail. You may fix it by adding webrick to your dependencies: bundle add webrick
Pass the --livereload option to serve to automatically refresh the page with each change you make to the source files: bundle exec jekyll serve --livereload
If you encounter any errors during this process, check that you have installed all the prerequisites in Requirements.
If you still have issues, see Troubleshooting.
Installation varies based on your operating system. See our guides for OS-specific instructions.

Adding Ajax pagination to Jekyll
‘About this Website’, by Carter Allen

“Jekyll is everything that I ever wanted in a blogging engine. Really. It isn’t perfect, but what’s excellent about it is that if there’s something wrong, I know exactly how it works and how to fix it. It runs on the your machine only, and is essentially an added “build” step between you and the browser. I coded this entire site in TextMate using standard HTML5 and CSS3, and then at the end I added just a few little variables to the markup. Presto-chango, my site is built and I am at peace with the world.”

A way to extend Jekyll without forking and modifying the Jekyll gem codebase and some portable Jekyll extensions that can be reused and shared.

Red Flags: AI claims without explaining what the AI does, customer logos without case study or testimonial evidence, no live product access or demo, SOC 2 claims without audit period or report availability, productivity claims without methodology, pricing hidden behind sales calls only…
Semantic Drift Patterns: homepage claims AI-powered but product is rules-based, claims enterprise-grade but pricing page shows startup tiers only, homepage shows Fortune 500 logos but case studies are small businesses, claims all-in-one but integration page shows critical missing pieces, free plan promoted but core features require expensive upgrade…
