Google Explains How To Use HTML Sitemaps For search engine optimisation

Google’s John Mueller and Martin Splitt not too long ago mentioned how HTML sitemaps should be helpful for search engine optimisation though the XML normal has largely changed it.

Pre-XML Sitemap Period

Earlier than the introduction of XML sitemaps, SEOs and web site house owners usually added inner and exterior hyperlinks to new internet pages to make sure that they bought crawled and began rating.

In addition they added a hyperlink from the footer of the house web page (or each web page) to an HTML sitemap the place a big listing of hyperlinks to internal pages may very well be crawled and support in getting these pages listed. Most SEOs populated the HTML sitemap with each web page on their web site that was thought of helpful to rank. Different pages, just like the About Us pages, have been left off of the HTML sitemap.

It’s doable that Google was already utilizing RSS feeds properly earlier than the introduction of XML sitemaps. For instance, a 2004 college analysis paper documented that RSS feeds may very well be utilized by internet crawlers to establish new and not too long ago modified internet pages and cut back crawling bandwidth by as much as 40%.

However as a result of RSS feeds weren’t universally applied, they have been seemingly impractical to make use of for crawl discovery. That’s most likely why GYM (Google, Yahoo, and Microsoft) joined forces to agree on a single XML sitemap normal that’s used to today.

HTML Sitemaps Not A Substitute For XML Sitemaps

Through the course of their current Search Off The File episode, Martin Splitt requested if SEOs and web site house owners have been locked into utilizing XML sitemaps OR if it was okay to make use of HTML sitemaps.

Google’s Mueller defined that HTML sitemaps should not a alternative for XML sitemaps as a result of they lack the structural options inherent in XML sitemaps.

He defined:

“Ah sure, HTML sitemaps. That I believe may be very complicated to the typical particular person since you most likely know what XML is and what HTML is, however lots of people after they open an XML file, they see these bizarre brackets and so they’re like, oh, that is HTML or very related, proper?

It seems to be like this bizarre programming stuff. And so they’re referred to as the identical, however an HTML sitemap is mainly virtually like a map of your web site for customers. It’s not one thing that replaces an XML sitemap file.

In fact, if somebody is crawling your web site and so they discover an HTML sitemap file, they’ll crawl these hyperlinks like every other hyperlink on a web site, in order that’s useful.

Nevertheless it’s not the case that the HTML sitemap may be submitted as a sitemap file. It could actually’t be processed one-to-one the identical method as an XML sitemap file as a result of it doesn’t have this strict construction to it. It’s mainly a group of hyperlinks.”

Considerably surprisingly, Google’s Mueller defined that HTML sitemaps can nonetheless be used. His reply implied deploying them as part of a navigational system for customers. Mueller used the instance of an ecommerce web site, however his reply can apply to any form of web site.

In his instance, an HTML sitemap permits web site guests to simply attain the top-level product (or subject) class pages from which web site guests can drill right down to a product (or subject) they’re thinking about.

His reply was in response to Martin Splitt’s query:

“However that also would assist crawling as a result of from this place we will discover all of the hyperlinks as properly. It’s simply not as structured and clear reduce as an XML sitemap, I assume.”

Mueller provided this reply:

“Sure, completely. And it’s one thing I believe that lots of HTML sitemaps, they don’t embody all the things.

So when you have an e-commerce web site, you wouldn’t listing all your merchandise in an HTML sitemap file. You’d listing possibly the classes so that folks can go to the best place, however then pick the product individually. So it’s related, however not precisely the identical.”

For others, the idea of an HTML sitemap is likely to be perceived as previous and outdated like listing hyperlinks or reciprocal hyperlink preparations. And but, Google’s John Mueller says that they are often helpful for customers, which implies HTML sitemaps may very well be helpful for Google.
