First off don't listen to all the b(LL@#(#%ers who claim things like page load time or "how your site looks" matter, because it doesn't. The crappiest looking blogs make the most money. You should be using a slim theme with the largest adsense block as close to the center of the screen as possible.
Maybe in Malaysia 7$ is a lot of money, but you seriously need to buy real domains.
What does "leafyard" have to do with "dog illnesses"? Zero keyword relevancy. At a bare minimum you could have made the subdomain "petmedications" instead of "blog."
Not to mention why did you pick dogs? Try to be creative.
Here is tip for you.
Go to ebay. Look for a specific type of product whether it be an article of mens clothing or model trains. Then register a domain with a specific attribute of the product in question.
I pick model trains because I have a related domain and it works well. So I know that there are different colored model trains, red, blue silver etc. But perhaps this is too specific so I think okay what are some popular scales (sizes) of trains?
Here is an example of a project I could do in about 15 minutes.
Register:
Code:
ho-scale-model-trains.com
Google adwords says...
"ho scale model train"
$0.35 - $0.51 1 - 3 0 $1
[ho scale model train]
$0.00 - $0.56 1 - 3 0 $0 - $1
"ho scale model trains"
$0.33 - $0.50 1 - 3 1 $1
[ho scale model trains]
$0.32 - $0.47 1 - 3 0 - 1 $1
So clearly this term gets a bit of traffic from the exact keywords alone (maybe around 20ish a day just from that term, hard to tell unless you run an adwords campaign) and the competition isn't bad especially if you have the actual keywords in the domain.
Definitely a buying keyword string.
Then I would upload my wordpress install plugins and put the keywords model trains, toy trains and upload the posts via article directory, not yahoo answers. Maybe pull some specific H0 yanswers but weed out the ones that don't make sense.
If you can't afford a real domain name then (re)write articles for a dollar an article. Americans always need crap SEO articles rewritten that will pass copyscape. I always need mortgage articles rewritten for a dollar a pop.
P.S. Looking at the click value, that is really low, but still it is just an example. Just try to find products with higher CPC.
