Effectiveness Of Specific Info On Online Advertising

I write my thought about effectiveness of specific info in online advertising  here (AdSense as example of  "general ads"). Is my hypothesis correct? Hmmm, I don't know :). But, its nothing to lose to prove it, eh? So, I try on my other blog www.galuhpakuan.org. This blog contains my personal note about company information (address, phone number, web site) and my description about that company. And it, I think, represents data I need: general info of a business entity.

After searching around web, advertising network that deliver "specific ads" is Chitika. Yes, its not contextual ads, so it is not perfect choice in my test. But I couldn't find better alternative. I put it in most strategic ad slot, alongside body post. And it will be replaced by other advertising network in same place next time (perhaps about two weeks) as comparison.

My test just begun yesterday, perhaps in weeks I could see the result: "specific ads" more effective then "general ads".

Note:
-Effective here meaning that "specific ads" attract the user to click ads then "general ads".
-This is my personal experiment of online ads on my blog, not endorsed by any party.

If Only Google AdSense And Product Search Get Married :)

AdSense usually delivers "general" ads. I mean, for example my posting about upgrading RAM acer 4738z, ads from an online computer store, typically will say "buy computer at our shop, cheap blah blah blah". I think its better if AdSense delivers ads "get acer 4738z for only $ 300..." or "KingStone DDR3 2GB for only $ 50..." with thumbnail of its product alongside ad text. My reader will know how to upgrade his Acer 4738z, and where to buy these stuff with best price.

Will advertiser get benefit? I believe, the answer is yes. In illustration above, my reader who visit advertiser know exactly what they want, "Now I know how to upgrade it, I want that RAM to upgrade my Acer, you offer me best price".

Advertiser: Product search is free, why should I pay for advertising on AdSense?
You not only invite visitor to your web site, but you invite potential buyer. How many seller you must compete on Product search? Why not you try offer your product directly to that potential buyer? You still promote your product on Product search service, while pay for penny on AdSense for less competitor per page.

People seem more interested in "product" not "seller" or "manufacturer" information. People know about NOKIA, for example, but they will find specific product from NOKIA rather then try to explore all its products. So, ads on "specific item" will be more effective then ads in "general".

Perhaps someday, AdSense will marry Product search :).

Web Hosting: Understanding Service They Offer

For those who came late...

*Shared Host:
One server will serve multiple web site (about 100/server). So, your web site will be placed on one server with others web site. You will get space for your scripts, database and mail based on package you buy. Usually 50% for script+database and 50% for mail. Some web hosting offer unlimited space, such Unlimited Hosting at GoDaddy.com.
Pros:

• Cheapest choice, its about $ 4/month.
