Question

Is it wise to submit a sitemap for tags to search engines?

Comments

But tags are large in numbers how can you submit them?

I can divide the site map in to 4 or 5 sitemaps for as long each sitemap is below 5MB. I just want to know if submitting tags won't destroy my website' SEO

Answer 1

No, not really. You should better don't include them (the same for categories).

That's the sitemap paradox -- if your site isn't being properly crawled (for whatever reason), using a sitemap will not help you!

Now it's worth mentioning that Google will pretty much index any important URL without the need of a sitemap, many don't even bother with a sitemap and ensure their site has a very friendly way of finding content without having to go down to deep in the URLs to discover the new content but others believe that a sitemap really does help Google.

Answer 3

No, you should not submit sitemap for tags. It would be better if you block them from robots.txt because tags pages will cause content duplicacy.
