# SEO Quality Checker, Internal Linking and Schema

The plugin includes a pre-publish SEO quality layer.

## What it checks

The plugin now checks title length, meta description length, focus keyphrase placement, heading structure, word count, paragraph readability, sentence length, secondary keyphrase use, image alt text, internal links, duplicate titles and selected section requirements.

## Internal Linking Agent

Enable **Auto-add internal links** to let the plugin search published posts and insert natural internal links into the article body. Use the internal-link limit to control how many links can be inserted.

## Related Articles Box

Enable **Add related articles box** to append a small related-posts section at the bottom of the article. This helps readers continue browsing and supports SEO crawling.

## Schema Controls

The schema tick boxes can output Article, FAQ, HowTo and Breadcrumb JSON-LD on the front end. HowTo schema is only used for True Tutorial Article mode. Schema JSON is stored in post meta and printed in `wp_head`.

## Rewrite Improvements

Generated Articles now include stronger rewrite modes such as Improve SEO Score, Add Internal Links, Expand Weak Sections, Add Missing FAQ and Add Missing Table / Graph.

## Safe defaults

The plugin creates drafts/pending posts first. Review the quality report before publishing important articles.
