Thanks Vicky,

I agree with you to create a site with closely related topics. Since I was mainly depending (originally) or organic search traffic I thought, hey someone will search on keywords "xyz abc " and land on a page on my site that talks about "xyz abc"

but you're right, if they want to find out about more stuff they'll be lost on the site, to address that problem I created a few pages related to "xyz abc" and put them on the side navigation bar. But that is not enough, I think it's better if the whole site is dedicated to a niche topic.

Unfortunatley I can't write volumes on things I'm not very familiar with. The only things I know in depth is computer programming, I'm thinking of building a site on programming. I'll build it offline first and when it has substantial content, I will host it since right now I'm already hosting 2 websites and its costing me every month especially when I don't have a source of income.

So when I get a job, may be I'll be able to focus on this.

Thanks for the encouragement.
