Does it matter to Google if the specified page is in the root folder or deeper? This question has been popping up for ages and let’s discuss all possible angles of it.
1. The page physical location hardly matters
Though it is often speculated Google likes root folders more, it is more about the "visibility" of the page and proper interlinking than its actual location. Any page linked to repeatedly and consistently throughout the site will be found, indexed and ranked just fine.
Quoting WebmasterWorld thread,
For many sites today, the url is only a dynamic and virtual representation of the site structure and there are no "real" folders – so a search engine will not find a valuable signal if it looks at things like presence or absence of directories.
A quick example indirectly proving this point is that for many years Google was recommending using numbers in the end of the file path to get accepted to Google news (which is no longer true btw). This /XXXXX/ part could possibly look like separate folder and it would be weird if Google advised to have it and used it as a dampening ranking factor in general search.
Important note: it is speculated that Google may be using "URL stripping" (i.e. dropping the file path to discover and crawl the folder), so if you are using "virtual folder" which returns no content or 404 status code when queried directly, this may result in extra crawl errors. In this case the file location relative to the root may matter to some extent.
What does matter is the URL length:
Extra folders may make your URLs look much longer and this may be not really good in some cases.
- User browsers can handle very long URLs: Microsoft Internet Explorer, for example, has a maximum uniform resource locator (URL) length of 2,083 characters.
- Users hardly pay attention to the URL in the browser address bar but shorter URLs do occasionally enhance user experience: for example, they are easier to remember and can improve the direct type-in traffic
This is called "intuitive URIs" when you can just type /your-word after the root and end up where you need to be.
- Best SEO URL practice: it is recommended to have no more than 3-5 words in the file path (note: this is not really about the whole URL but the actual file path after the last / in the URL but should be mentioned anyway as it indirectly demonstrates Google’s overall treatment of the URL length):
According to Google’s Matt Cutts if there are more than 5 words…
[Google] algorithms typically will just weight those words less and just not give you as much credit.”
- Click-through: this research shows that short URLs within Google SERPs get clicked twice as often as long ones. Besides, longer URLs are cut off in Google SERPs – so the end user can’t see where he is going to land, this should be decreasing the click-through immensely.
