Google’s John Mueller and Martin Splitt just lately mentioned how HTML sitemaps should be helpful for search engine marketing although the XML normal has largely changed it.
Pre-XML Sitemap Period
Earlier than the introduction of XML sitemaps, SEOs and web site homeowners sometimes added inner and exterior hyperlinks to new net pages to make sure that they bought crawled and began rating.
Additionally they added a hyperlink from the footer of the house web page (or each web page) to an HTML sitemap the place a huge listing of hyperlinks to internal pages may very well be crawled and assist in getting these pages listed. Most SEOs populated the HTML sitemap with each web page on their web site that was thought-about helpful to rank. Different pages, just like the About Us pages, had been left off of the HTML sitemap.
It’s potential that Google was already utilizing RSS feeds nicely earlier than the introduction of XML sitemaps. For instance, a 2004 college analysis paper documented that RSS feeds may very well be utilized by net crawlers to determine new and just lately modified net pages and cut back crawling bandwidth by as much as 40%.
However as a result of RSS feeds weren’t universally carried out, they had been probably 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 this present day.
HTML Sitemaps Not A Substitute For XML Sitemaps
In the course of the course of their latest Search Off The File episode, Martin Splitt requested if SEOs and web site homeowners had been locked into utilizing XML sitemaps OR if it was okay to make use of HTML sitemaps.
Google’s Mueller defined that HTML sitemaps usually are 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 could be very complicated to the common individual since you most likely know what XML is and what HTML is, however lots of people once they open an XML file, they see these bizarre brackets they usually’re like, oh, that is HTML or very comparable, 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 they usually discover an HTML sitemap file, they’ll crawl these hyperlinks like some other hyperlink on a web site, in order that’s useful.
Nevertheless it’s not the case that the HTML sitemap might be submitted as a sitemap file. It might probably’t be processed one-to-one the identical manner 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.”
Google Explains How To Use HTML Sitemaps
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 type of web site.
In his instance, an HTML sitemap allows 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 taken with.
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 nicely. It’s simply not as structured and clear reduce as an XML sitemap, I suppose.”
Mueller provided this reply:
“Sure, completely. And it’s one thing I believe that quite a lot of HTML sitemaps, they don’t embody every thing.
So when you’ve got an e-commerce web site, you wouldn’t listing your entire merchandise in an HTML sitemap file. You’ll listing possibly the classes so that individuals can go to the best place, however then select the product individually. So it’s comparable, however not precisely the identical.”

For others, the idea of an HTML sitemap could 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.
For those who’re going to do it, do it in a manner that’s helpful for customers, and you could discover that web site guests will begin utilizing and recommending extra pages from the location, and Google will choose up on these indicators.
