(06) — FAQ

Common questions.

Are all features included, with no paywall?

Yes. Every feature is available to every user. There are no license gates, trial limits or upsell tiers in the code.

Where is my XML sitemap?

It is generated automatically at https://yourdomain.com/sitemap.xml.

Does it conflict with schema plugins?

No. It is designed to hand structured data to a dedicated schema plugin (such as BuildForUser Schema LD Generator) so there is no duplicate JSON-LD.

How does the pixel-width meter work?

Google truncates titles by pixel width (about 600px on desktop), not character count. The preview measures the real rendered width of your title with HTML5 Canvas.

Can I import my metadata from Yoast SEO or Rank Math?

Yes. Go to BFU SEO › Tools › Importer to migrate focus keywords, SEO titles, descriptions and canonical URLs in one click. All in One SEO is supported too.
