Snippet Library
SEO snippets for WordPress
Snippets for search engine basics: meta descriptions, Open Graph tags, structured data, noindex rules and robots.txt changes. Lightweight options for sites that do not run a full SEO plugin, or need one specific fix.
Noindex Category and Tag Pages With Few Posts
Adds noindex to category, tag and custom taxonomy archives that hold fewer posts than a minimum, so near-empty pages do not dilute your search presence.
