Chronition SEO

Chronition SEO is a complete, lightweight SEO plugin. It covers everything a content site needs to rank, and it can replace Rank Math without editing a single page.

Premium table of contents

• A modern, accessible table of contents with numbered sections (1, 1.1, 1.2…), smooth scrolling, the current section highlighted while reading, and a floating “Contents” button with a reading-progress ring.

• Existing Rank Math “Table of Contents” blocks are automatically drawn with the new design — on every page, without updating any of them.

• Add it automatically to posts, or place it with the block or the [cwseo_toc] shortcode.

• “Match theme” style that blends in with any theme — it uses the theme’s own fonts, link colour and background — plus card, outline and minimal styles; or pick a custom accent colour. Dark mode and print friendly.

• One or two columns (or automatic: two columns for long tables of contents), site-wide, per page, per block or per shortcode ( [cwseo_toc columns="2"] ). Always one column on phones.

Titles, meta and social

• SEO titles and descriptions for every post type, taxonomy, archive, search and 404 page, with the same %variables% as Rank Math.

• A post editor box with a live Google preview (desktop and mobile), length meters, a focus keyword and a content check with a score out of 100.

• Every page and post can override the site-wide settings: title and description, index/noindex, follow/nofollow, noarchive/nosnippet/noimageindex, Google preview limits (max-snippet, max-image-preview, max-video-preview), sitemap inclusion, table of contents (show/hide, title, heading levels), schema type, canonical URL, breadcrumb title, primary category and social cards. Each field shows the site default next to it, tabs with custom values are marked, and one click resets the page to the site defaults.

• Open Graph and X (Twitter) cards, canonical URLs, robots meta (noindex, nofollow, max-snippet…).

Sitemaps and fast indexing

• Google-friendly XML sitemaps at /sitemap_index.xml — the same address Rank Math uses, so Search Console keeps working — and at /sitemap.xml. Includes images, last-modified dates, and skips noindex and redirected content automatically.

• A “Your sitemap” panel with View and Copy link buttons, the number of links in each sitemap, and an “Update sitemap now” button.

• Optionally keep a real sitemap.xml file in the site folder, rewritten automatically when content changes.

• IndexNow instant indexing (Bing, Yandex, Seznam, Naver and others): new and updated posts are submitted automatically, plus manual and bulk submission with a log.

Schema (structured data)

• Organization or Person, WebSite with sitelinks search box, WebPage, Article/BlogPosting/NewsArticle, BreadcrumbList.

• FAQPage and HowTo rich results from Rank Math FAQ and HowTo blocks.

• Custom schema created in Rank Math (Product, Recipe, Event…) keeps being output.

Redirects and 404 monitor

• 301, 302, 307, 410 and 451 redirects with exact, contains, starts-with, ends-with and regex matching, hit counts, and CSV import/export.

• Automatic redirect when you change a published post’s address.

• 404 monitor that shows which missing addresses people and search engines tried, with one-click “Redirect”.

Also included

• Breadcrumbs (block, [cwseo_breadcrumbs] shortcode, and Rank Math’s [rank_math_breadcrumb] shortcode and functions keep working).

• robots.txt editor.

• Automatic image alt and title text for images that have none.

• Open external links in a new tab and/or mark them nofollow.

Moving from Rank Math

• Install and activate Chronition SEO. While Rank Math is active, Chronition SEO stays in standby — only the new table of contents design is applied, so you never get duplicate tags.

• Go to Chronition SEO → Import & Tools and click “Import everything from Rank Math”. Settings, per-post and per-category SEO data, and redirects are copied. Rank Math’s data is not changed.

• Deactivate Rank Math. Chronition SEO takes over immediately. Rank Math FAQ, HowTo and Table of Contents blocks keep displaying on your pages.

Even before importing, Chronition SEO reads Rank Math’s saved titles, descriptions, robots and social fields, so nothing is lost at the moment of switching.

Chronition SEO Pro (optional add-on)

Everything above is free and complete. in/plugins/chronition-seo-pro/ for sites that need more: a schema builder (Product, Recipe, Event, Course, Video, Job, Review, Person, Book), Local SEO with multiple locations, a sticky sidebar table of contents, news and video sitemaps, 404 e-mail alerts with suggested redirects, a bulk SEO editor, multiple focus keywords with internal link suggestions, and WooCommerce product SEO.

External services

This plugin can connect to the IndexNow API to tell search engines that a page was added, updated or deleted, so it is crawled sooner.

• Service: IndexNow, operated jointly by participating search engines (Microsoft Bing, Yandex, Seznam.cz, Naver and others), at https://api.indexnow.org/indexnow

• When: only if “IndexNow” is switched on under Chronition SEO → Sitemap & Indexing. It is off by default; importing from Rank Math switches it on only if Rank Math’s own IndexNow (Instant Indexing) feature was in use. Then a request is sent when a post of a selected type is published, updated or deleted, or when you press one of the “Submit” buttons.

• What is sent: the page addresses (URLs), your site’s host name, your IndexNow key and the address of your key file. No personal data about visitors or users is sent.

• Terms: https://www.indexnow.org/terms — FAQ: https://www.indexnow.org/faq — Privacy (Microsoft Bing, which runs api.indexnow.org): https://www.microsoft.com/en-us/privacy/privacystatement

• IndexNow is never contacted from local or non-public sites.

No other external requests are made. The plugin does not load any remote scripts, fonts or images.
