This website has been a good source of passive income for me. I spent time to update the content and I make sure the content is relevant to the niche.
I have used many freelancers from odesk to help me with content and I am lucky that my web hosting provider (smart seo hosting) is a topnotch provider. They are not a cheap provider, hosting with them costs more than few cent for month but then they care for their customers. We get to choice from their wide range of datacenters, which is now more than 90 and host our content on different geolocations.
Their offering is like a smart geolocation based content serving platform.
Some might ask if this really matters, well from my experience, having your domain on extremely fast servers and on reputable datacenters with fast links to internet and with almost 100% up time always helps and for us personally we got a good boost in our search result ranking for keywords that we really cared.
