Geology Explains 0–100 Meta Tag Scoring Rubric
Geology published a detailed write-up explaining the rubric behind its Meta Tag Analyzer, describing how dozens of binary meta-tag checks are aggregated into a single 0–100 score. The tool groups checks into five weighted dimensions (Basic meta, Headings, Open Graph, Twitter Card, Technical), applies graded penalties (fail = -40, warning = -20 within a dimension), and uses a weighted average except for a hard noindex failure that can zero a page's prospects. The analyzer returns up to three prioritized recommendations, ranked by dimension weight × score deficit. Thresholds for title and description lengths are based on observed truncation behaviour, and extraction runs on server-rendered HTML parsed with BeautifulSoup. Geology also offers an OG Previewer to render how link cards appear on platforms like Facebook, X, LinkedIn and Slack. The article is authored by Mehul Jain and published 2026-06-04.
Practical documentation of a metadata scoring methodology helps publishers and MarTech users prioritize fixes that improve search and social link rendering, but it is a vendor-level tool rather than an industry-shifting announcement.

Key Takeaways & Evidence Grounding
- Geology groups meta-tag checks into five dimensions with fixed weights: Basic meta (30%), Headings (20%), Open Graph (20%), Twitter Card (15%), Technical (15%).
- Within a dimension, a failing item subtracts 40 points and a warning subtracts 20 points from that dimension's score.
- The overall score is a weighted average of dimensions, with one explicit exception: a robots noindex check can fail hard and effectively zero the page's discoverability.
- The tool limits recommendations to at most three top-priority fixes, ranked by (dimension weight × score deficit).
- Extraction runs on server-rendered HTML parsed with BeautifulSoup; the Meta Tag Analyzer and an OG Previewer are publicly available (getgeology.com).

GEO Is the New SEO — Most Sites Fail
The author built a Generative Engine Optimization (GEO) agent inside WebScore to measure how discoverable websites are to AI engines (e.g., ChatGPT, Perplexity, Gemini, Claude). The article identifies key signals that influence AI visibility: llms.txt, E-E-A-T signals (author attribution, About/Contact pages, organization schema), FAQPage JSON-LD, outbound authority citations, a Wikidata entry, and allowing AI crawlers in robots.txt. Scanning real sites, the author reports widespread gaps — about 80% lack llms.txt, ~70% lack FAQ schema, and ~60% unintentionally block at least one major AI crawler — and claims sites with Wikidata entries are cited roughly three times more often. WebScore returns metrics like AI Mention Rate and Citation Rate and an ordered issue list for fixes.
SEO for Developers Beyond Meta Tags
The article argues that modern SEO is primarily an engineering problem rather than a simple metadata checklist. It highlights performance (Core Web Vitals) and accessibility as ranking factors, warns about Cumulative Layout Shift (CLS) and large JavaScript bundles, and recommends using SSR or SSG instead of pure client-side rendering for indexable pages. The piece stresses semantic HTML (h1, article, nav) to provide machine-readable structure, advocates descriptive, human-friendly URLs and 301 redirects when changing structure, and advises controlling crawl budget via robots.txt to prevent bots from wasting time on duplicate or non-public pages. It concludes with a three-question pre-merge checklist for developers to ensure pages are fast, accessible, and structurally sound before shipping.
Website Metadata Checklist for Better Previews
A practical checklist for auditing and fixing website metadata so link previews, search snippets, and browser icons render correctly outside the browser. The article explains why metadata (titles, descriptions, favicons, canonical URLs, Open Graph/Twitter cards, robots.txt, and sitemaps) matters, shares a real-world example from the author's portfolio (wrong OG image size and no on-image text), and lists verification tools and steps. It also points toward agentic browsing and AI-agent readiness (llms.txt, layout stability, WebMCP) as advanced follow-ups after basic metadata is correct.
