Why does alexa block free domains even if your site gets a good amount of hits each month alexa still will not list it. Alexa only allows the main site for that domain not other site using that domain. Why does Google block 70% of sites using free domains for you site to get listed on google your site need to get at least 30k to 50k hits a month
I don't think Google blocks free domains, for example: *.blogspot.com, *.wordpess.com etc. are all free domains still you can find them in top positions on search engine ranking pages. as far as Alexa is concerned, you are right about it and i haven't noticed any sub-domain being listed at Alexa all you will find is a top level domain
