Frequently Asked

Module 3 Questions

Common questions about specialised sitemaps, drawn from the issues that come up most often when these types are being implemented.

Do I need every specialised sitemap type for my site?
No. Each specialised type addresses a specific scenario. Image sitemaps help sites where images carry real content value. Video sitemaps help sites with self-hosted video. News sitemaps only help Google News-approved publishers. Hreflang sitemaps help sites with international or multilingual content. Most sites need one or two of these, not all four.
Can image, video, and hreflang sit in the same sitemap file?
Yes. Each type uses a different XML namespace, and they coexist in the same urlset by declaring all the namespaces at the top of the file. A single url entry can include image:image, video:video, and xhtml:link elements together when the page has all three.
Why is the news sitemap always its own file?
Three reasons. The 1,000 URL cap on news sitemaps would constrain a combined sitemap unnecessarily. The 48-hour freshness window requires constant pruning that does not apply to the standard sitemap. And Search Console reports news sitemap activity separately, so combining them muddies the data.
Do I need a sitemap index if I only have one specialised sitemap?
No. The sitemap index pattern is for orchestrating multiple sitemap files. If you have a single sitemap (with or without inline specialised metadata), you submit that one file directly to Search Console without an index.
What about videos hosted on YouTube?
YouTube indexes its own content through its parent infrastructure. Adding YouTube embed URLs to your video sitemap rarely helps because YouTube already has those videos indexed. Video sitemaps are most useful for video files you self-host on your own domain or CDN.
Is sitemap-based hreflang better than HTML hreflang tags?
The engines treat both equally. The choice is about practicality. Sitemap-based hreflang centralises the signals into one file, which makes maintenance easier at scale. HTML hreflang tags are simpler for small sites and integrate better with most CMSes. The rule is: pick one method and stick with it.
Does my CMS handle specialised sitemaps automatically?
It depends on the CMS and the SEO plugin. WordPress with Yoast, Rank Math, or All in One SEO generally handles image sitemap entries inline by default. Video and news sitemap support usually requires a Pro tier or dedicated add-on. Hreflang implementation varies significantly between multilingual plugins.
Should I still use mRSS for video sitemap submission?
No. The XML video sitemap extension has replaced mRSS for new implementations. mRSS still works if you have an existing feed, but it is not recommended going forward. Lesson 3 covers the XML video sitemap setup that makes mRSS unnecessary.
