Do Subdomain Hits Improve Alexa Ranking?

Do Subdomain Hits Improve Alexa Ranking? For the big sites Alexa lists out the sub domains and it says, "Where people go on..." followed by a list of sub domains. Here is an example. It concerns a site that has a high Alexa ranking:

Alexa subdomain tracking

This site is a subdomain of (PoC). You can see that in the address bar at the top of the page; there is a dot before the pictures of cats url and the address before the dot is the subdomain. It is important for me to know if this subdomain contributes directly to the Alexa ranking. In other words, do the hits and pageviews per visitor etc. to this subdomain website get added to the hits from the "main site" (PoC) to produce a combined figure?

Well, when I first built this Blogger site and made it a subdomain, Alexa used to list it (just like it lists the subdomains for Sitesell above). And it provided a percentage contribution as well.

That at least means the Alexa was and is (judging by the above) measuring hits from the subdomains. Otherwise it would not be able to tell us the percentage of people who visit them. At the moment Alexa does not show this site as a subdomain (as it used to) but Alexa does refine and change what it shows us (update at March 2011 - it is now showing subdomains, see image below). The recent changes bear that out. The point I am making is that Alexa is still measuring visits to subdomains but unless your site is ranked very highly it won't show the percentages as for

March 2011: Showing subdomains for PoC

Alexa say this about subdomains:
"Alexa's traffic rankings are for top level domains only (e.g. We do not provide separate rankings for subpages within a domain (e.g. or subdomains (e.g.

All this says is that Alexa does not rank subdomains separately. In other words it just ranks one website, the main site. This actually gives us the answer, I believe. We can infer from this statement that it balls the figures for subdomains and main domain together as this is the opposite to ranking separately. That in any case is my assessment of the matter and I think it makes sense. Do Subdomain Hits Improve Alexa Ranking? Yes, in my view. One last point.

Another subdomain to PoC is this site: I asked this lady, Valley Girl (VG), if she would join PoC as a subdomain. She had just started her Blogger blog. She agreed, I am pleased to say, as she is a great asset. Her blog achieved a Page rank of 4 in about 4 months. This is better than PoC (PR 3) and this site (PR 3). I wondered why there was no great improvement in my Alexa ranking. I think the answer is the commonsense one. VG has a nice site and a damn good PR but not much traffic. Lets say she gets 100 visits a day. PoC gets about 6,000 unique hits a day (Google Analytics). This site gets over 2,000. So VG's contribution currently (and this will change) is small in terms of Alexa ranking. 100 hits represents 1.67% of the total hits and will not show up on Alexa, which is not that accurate anyway for sites outside the top 100,000 (PoC is ranked about 117,000). Even if she gets 600 hits a day it represents 10% of the total.

Update: Here is a screen shot of the Alexa web page in relation to

subdomain keywordsSome of the keywords come from this sub domain, namely:
  • cat poison
  • alexa algorithm has been changed
Indicating that Alexa is reading sub domain information.

Feb 2011, update: Below: this shows Alexa statistics in relation to subdomains at as at this date. It is clear from this that Alexa recognizes subdomains and it is worth noting that the founder of Sitesell, Dr. Ken Evoy is a talented SEO expert. Would he jeopardize the SEO of his website and subdomains? He likes a good Alexa ranking and his site has a good number of subdomains. What I am saying is that Alexa recognizes subdomains and in doing so subdomains will improve the Alexa ranking if they are worthwhile web pages that collect hits. The forums at SiteSell are probably the most visited part or SiteSell and it is a subdomain (see below):

Screenshot from Alexa
One last point. Google sees subdomains as a different website to the main domain. So, if I have two similar pages on the same subject one on the main site and the other on a subdomain, Google might list them both out, one below the other in a search result. See below:

From Do Subdomain Hits Improve Alexa Ranking? to Home Page

so is the final answer yes?

Response to last comment....

You know I am not sure, sorry (I though I was!). The reason is that Alexa also refers to pages on this sub-domain site as pages that bring traffic to the main site. It list entirely different web sites in the same list.

That indicates that Alexa sees this site as a different website.

I am yet to see clear information on this. said…
Hi, I am also confused about Alexa's ranking system in regards to main site and its subdomains. Here's my case. I run a very popular web site which in September 09 was ranked under 100K on alexa. Since then I added a sub domain mainly for adsense, where I would post some content on it and send traffic from main site to this videos subdomain. In about three months, I noticed Alexa ranking for Dalkanews dropped from under 100K to above 200K. The traffic I was getting appeared to be the same on my end (using local stats). I kept the sub domain because I was making some good money from it via Adsense and sign ups. Any how, my site now is ranked above 900K. Tell me how this is possible? Keep in mind, most of the traffic bounces off the main site to the sub domain, so I still get the same traffic I was getting when the site was ranked under 100K, only difference is my visitors are going to videos.. sub domain.

Got an idea what has happened?

Hi Dalkanews,

Your story just does not make sense. But there are some things about Alexa that do not make sense. I don't think it is that accurate at about 100K mark, which may be a factor.

Secondly, the Alexa ranking has peaks and troughs that are quite steep for me but when my traffic is measured from a different source it is very stable so I conclude that Alexa move the graph around to generate interest, which is understandable as a straight line on a graph day in day out would stop people visiting their site.

I am not sure that the introduction of your subdomain actually made any impact. The movement could be due to some other reason like changing the criteria. The subdomains I have did not affect ranking.

I do find that the subdomains are worth having as I can make a quick post and keep the thing fresh. My subdomains are Blogger ones and Google likes to pick up its sites quickly.

Sorry I am vague about this but the whole thing is imprecise.

I said no more spam promotions on this page please. They will be deleted so you are wasting your time.

This is the main reason our web staff redirect www.domain.tld to domain.tld as www is a subdomain.

Since doing so, our PR jumped from 0 to 3 in 5 weeks and the Alexa rank is increasing. The Alexa rank increased so much that it passed our competitor and ranked for the USA. There site is not ranking for India and is visited by spammers.

Cat Ear Mites

Brown gunge. Yes, I know this is a ferret! It does show the build up of dark brown to black ear wax caused by the presence of the cat ear mites in the outer ear canal. This parasite is not restricted to the domestic cat, which makes this photo valid and a useful illustration (I was unable to find a suitable photo of a cat with the condition). Photo Stacy Lynn Baum under a creative commons license. Ear mites (minute crab like creatures) are one of the causes of inflammation of the outer ear canal (scientific term for this inflammation is Otitis externa ). The outer ear canal is the tube that runs from outside to the ear drum (the pathway for the reception of sound), which can be seen when looking at the ear. Otitis externa affects humans and often swimmers as it is called "swimmer's ear" in humans. This YouTube video show ear mites under a microscope. They are not actually in the ear in this video. There are many possible causes of Otitis externa in c

Feline Mange

I'll write about three types of feline mange (a) feline scabies or head mange (b) demodectic mange and (c) sarcoptic mange. The source material is from Cat Owner's Home Veterinary Handbook - the best on the market . Generalised feline mange? Puerto Rico - Photo by Gotham City Lost And Found Feline Scabies - head mange Head mange or feline scabies, is a fairly rare condition in cats, which is caused by the Notoedres mite (head mite) that only reproduces on cats. The female mites burrow a few millimeters (that is a lot) into the skin around the head, and neck to lay eggs, which hatch and lay their own eggs. Their presence and activities causes intense itching that in turn causes the cat to scratch. The scratching will obviously be noticed and it will cause the skin to become red, scratched and worse infected. Symptoms: hair loss and scabs, thick wrinkled skin and grey/yellow crusts form plus the symptoms of scratching. Feline mange (head mange) is contagious and tr

Cat Anatomy

Cat Anatomy - Photo by Curious Expeditions . The picture above was taken at Wax Anatomical Models at La Specola in Florence, Italy. The photograph is published under a creative commons license kindly granted by the photographer. I am sorry if it is a bit gruesome. It is pretty well all I could find as an illustration that was licensed for publication. Cat Anatomy is a very wide ranging subject. The anatomy of a cat is very similar to human anatomy. If you were writing a biology book for students of biology you would go through every part of the a cat's anatomy in some detail. It would be similar to writing a book about the human anatomy. It would be a thick book and pretty boring for your average internet surfer. So, how do you limit such a big subject and make this post meaningful? The answer I think lies in doing two things: Having a quick general look at cat anatomy - an overview and; Focusing on the areas of cat anatomy that are particular to the cat and of parti
