Every page needs a unique, descriptive <title>. It is the strongest on-page ranking signal and the headline shown in search results.

A 140–160 character meta description summarises the page for search engines and click-through.

The canonical tag tells Google which URL to consolidate ranking signals to when duplicates exist.

OG tags control how your page appears when shared on Slack, LinkedIn, Facebook, WhatsApp, X, etc.

JSON-LD is how you qualify for SERP rich results (stars, FAQs, prices, breadcrumbs) and AI search citations.

78% of structured-data errors are syntax (missing comma, smart quotes, unclosed bracket). A single typo invalidates the entire block.

Every page should have exactly one H1 that names its primary topic.

Alt text is required for accessibility (WCAG) and image SEO. Use alt="" for purely decorative images.

HTTPS is mandatory in 2026 — Chrome marks HTTP pages "Not Secure" and Google uses HTTPS as a ranking signal.

HSTS forces browsers to upgrade HTTP requests to HTTPS automatically, preventing downgrade attacks.

robots.txt is the standard way to tell crawlers which paths to skip and where to find sitemaps.

Sitemaps give search engines a definitive URL list with lastmod hints.

llms.txt is the emerging convention (2024-26) for telling AI crawlers what your site is about and what pages matter.

GPTBot, ClaudeBot, PerplexityBot, etc. need access to your content to cite you in AI search answers.

AI engines cite pages that state the answer plainly in the first paragraph. Pages that "set up" the topic before answering get skipped.

AI engines lift individual paragraphs as citations. Paragraphs relying on "this", "it", "as mentioned" are less likely to be extracted.

Google's E-E-A-T framework and AI engines both prefer cited content with clear authorship.
