Site Architecture

A site’s architecture refers to the structure of pages on a website and how they are linked together. Site architecture affects how search engine’s crawl a website and how users navigate through a site. As an important factor for SEO, our Hangout Notes cover best practice guidance and advice to ensure your site architecture is optimally structured. To learn more about the ins and outs of this topic, make sure you check out our Ultimate Guide to Site Architecture Optimisation.

URL structure does not make a page appear closer to the homepage – Google looks at internal linking instead

Google uses internal linking rather than folder structure to understand how close a page is to the homepage. So if a particular URL includes many subdirectories (aka if a URL has many slashes in it) — or if it has only one — the site’s overall architecture would be viewed by Google based on the internal linking (rather basing this structural understanding on the URL’s format). Google Search cares much more about internal linking structures than folder or URL structures.

“Just looking at the number of slashes in a URL doesn’t tell us that this [page] is lower level or higher level [within the site]. It’s really, from the homepage, or from the primary page, how quickly can we reach that specific page?” said Mueller.

Allow a Single Variation of Category Pages to be Indexed

Google doesn’t currently have guidelines on indexing different versions of category pages, but is moving towards recommending allowing a single version to be indexed, such as a sort order, and the alternative variations with different filters and sort orders should be noindexed. If there are other specific versions of category pages which are important, you can allow the first page in the set to be indexed as well.

Excessively Flat Site Hierarchy May Confuse Google

An excessively flat site architecture, such as having a very large sitewide navigation or linking to all pages in a paginated set from page 1, may confuse Google about the site hierarchy, which page to rank, and what to show as Sitelinks.

Sites Sharing IP Addresses Isn’t a Problem For Google

Only Use Separate URLs For Similar Products if They Match Separate Specific Queries

It’s usually better to consolidate signals for different product variations by using one URL. You might want to split them out if they match specific user search intents though, as one main product page might be too generic for certain queries.

Splitting or Merging Websites May Change Rankings

If you’re moving a whole website to a different domain, Google can move the signals across for the whole site. But if you’re splitting off part of a site to a new domain, or merging multiple websites, then the rankings may change as Google has to revaluate the sites individually.

Merging Internal or External Pages on One Topic Will Result in Higher Rankings

If separate sites that rank well already and both focus on the same topic or service merge, then they will see an increase in rankings as Google sees an even stronger page than before.
