Canonical URLs on Archive Pages
Adds canonical link tags to the blog page, category, tag, author and post type archives, which WordPress only does for single posts and pages by default.
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 Author Archives
Keeps author archive pages out of search results while their links are still followed, which suits single-author blogs where they duplicate the main blog.
Remove ?replytocom From Comment Reply Links
Stops comment reply links from creating ?replytocom= URLs that crawlers treat as duplicate pages, and redirects any such URL to the clean post address.
