Welcome to the Q&A Forum

John,

Thanks so much for the reply – So there's no harm in submitting a secondary sitemap, specifically for landing pages? Great to hear and yes, many of the landing pages overlap for both SEO and PPC.

Thanks!
Brendan

John,

Good to know – At this point I only have our primary sitemap submitted to Search Console, but I will create and add a secondary sitemap. I don't see us adding a ton of secondary-like sitemaps, you still suggest making a sitemap index of sorts?
