SEO Tools

Screen reader users navigate pages primarily through headings — 67% according to WebAIM surveys. Here's how WCAG requires proper heading structure, the rules for hierarchy and H1 usage, accessibility failures that also hurt SEO, and tools for auditing heading structure.

React and Vue SPAs often inject canonical tags via JavaScript — which Googlebot sees only after rendering, with a processing delay. Here's how Next.js SSR handles canonicals correctly, how to manage e-commerce faceted navigation, and how to verify what Google actually sees.

A page can have visually-perfect headings — right size, right boldness, right spacing — while having a completely empty semantic heading structure underneath, because CSS can style any element to "look like" a heading regardless of what HTML element it actually is. Here's why "div soup" headings happen with visual page builders, why a sparse heading-extraction result for a competitor's visually-organized page is genuinely meaningful (not misleading), and how to check whether your own visual headings are actually marked up correctly.

The OG image is the most underinvested part of social media marketing. Here's what makes social preview images drive clicks: dimensions, contrast, readable text at thumbnail size, template-based generation at scale, and platform-specific caching considerations.

Most "toxic" backlinks are simply ignored by Google, not penalised. The Disavow Tool is often misused to surrender legitimate link equity. Here's how to run a real backlink audit, what actually warrants disavowal, how to structure a disavow file, and why most sites rarely need it.

Two pages on your own site competing for the same search query is a fully within-your-control problem — yet one of the most common issues found in SEO audits, often developing through organic content growth without coordination. Here's how to identify cannibalization via Search Console ranking fluctuation, when to consolidate vs differentiate competing pages, and when apparent overlap isn't actually a problem.

Google's SERP has changed more in three years than the previous decade — and "10 blue links" is now one of several possible layouts. Here's how AI Overviews change what it means to rank in a given position (and why position 1 below an AI Overview gets less click-through than position 1 without one), what SERP preview tools are actually good for in this context (truncation checking, rendering errors, mobile vs desktop), and why title/description still matter but for partially different reasons.

Google rewrites title tags in 30–60% of cases depending on the site. Here's what triggers rewrites, what Google substitutes instead, and how to write titles that get left alone — with guidance on length, keyword use, and the brand name question.
