Good morning MOZ Community, We've been doing some re-vamping recently on our primary sitemap, and it's currently being reindexed by the search engines. We have also been developing landing pages, both for SEO and SEM. Specifically for SEO, the pages are focused on specific, long-tail search terms for a number of our niche areas of focus. Should I, or do I need to be considering a separate sitemap for these? Everything I have read about sitemaps simply indicates that if a site has over 50 thousand pages or so, then you need to split a sitemap. Do I need to worry about a sitemap for landing pages? Or simply add them to our primary sitemap? Thanks in advance for your insights and advice.
