FAQ

What SEO fields can I edit on posts and pages?: You can edit the SEO title, meta description, canonical URL, robots settings, sitemap inclusion, social sharing fields and supported schema fields for enabled post types.
What is the sitemap URL?: The sitemap index is available at /holoseo-sitemap.xml after permalinks have been refreshed. Activation refreshes rewrite rules automatically.
Can I control schema output?: Yes. HoloSEO includes supported schema types for common pages, articles, businesses, services, products, FAQs, HowTo content, events, courses, videos, software, jobs, books and reviews. Schema-specific fields stay hidden until a schema type is selected.
Can I import metadata from another SEO plugin?: Yes. The Import/Export screen can import common SEO titles, meta descriptions, canonical URLs, robots controls, social metadata and compatible site-wide settings from major SEO plugins. Existing HoloSEO values are preserved unless you choose to overwrite them.
Does it try to avoid duplicate SEO output?: Yes. HoloSEO includes conflict checks for common SEO plugins and is designed to output clean metadata without unnecessary duplicate tags.
Can I remove plugin data on uninstall?: Yes. Enable the clean uninstall option in HoloSEO settings before uninstalling if you want HoloSEO options, redirects, 404 logs and stored HoloSEO post meta removed.
