Is PR and Alexa rank important?

17 Comments

After my site was removed from Google SERP (only index page effected), everything has changed. The recent Google PR update gives me PR0. I heard that many of other bloggers facing the same problem because they sell link ads on their website. Google has changed their PR algorithm and the changes have effect many blog sand websites who do the link selling. It is kind of a penalty for those who use the advantages of their high PR.

PR drop will affect my website revenue. Link selling is my second incomes after Adsense. But because Google has dropped my PR, so my earning will decrease too. That’s mean, I need to find other way to increase back my earnings. But the question is how?

Not only PR, my Alexa ranking also dropped. Before this, my site was around 50K but now it is 90K. Maybe because I removed the Alexa ranking code from my new theme but does Alexa rank is important for your site? If your main money income is from Text Link Ads, for sure it is important. Because Text Link Ads use many criteria to set the prices for each links sold on your website. Some of it is, Alexa rank.

Servers in Malaysia and Sweden hosted virus

There is a report saying that recent virus attacks regarding the email containing malicious PDF files are coming from servers in Malaysia and Sweden.

“The emails, sent in bulk, looked like credit-card statements, and contained an attachment called ‘report.pdf’,” chief research officer Mikko Hypponen said in a statement.

When such PDF files are viewed on vulnerable machines, they start downloading software from servers in Malaysia or Sweden, which are now being cleaned, he said. “There will be more such attacks.”

To prevent your PC from being infected, a new security update for Adobe Acrobat Reader has been released a few days ago. But there is a question that I want to ask, what should we do to the company who hosted the server in Malaysia? Maybe we might need to ban the provider. Because of them, Malaysia get bad reputation in security and IT field.

5 tips to increase Adsense earnings

14 Comments

I’m not the expert in Adsense but I would like to share my experience and knowledge about how you can increase your Adsense earnings. I’m sure many of you already know what is Adsense. Adsense is a way for you as the publishers to earn money from your site. As for the advertisers, you can get more traffics to your website by using the advertising programme from Adsense. It is a win-win situation. Ok, let’s go to the main point of this article, 5 tips to increase Adsense earnings .

The first time I got accepted into Google Adsense programme, I was so excited because I know that I can start making big money from it. But I was wrong. By get accepted into Adsense does not mean you can earn the money easily. The money that I got for the first five months were very low. It was about $2 or $3 per month. But after I read articles, do some experiments, asked opinions from Adsense experts other Adsense users, I end with these tips. And these tips have increase my Adsense earnings.

1. Use large ad size – First what I did to my site was, I use large ad size. The theory is simple. The bigger the size, the higher chances the visitors will click the ads. Large ad size serves more ads (3 or 4 ads per ad unit) and it gives more choices for visitors to click.

2. Place above the article – Next, put the ad unit above the article. As you can see on my website, the ad is placed above the article, below the title. So far, this is the best place if you want to place your Adsense ad. My CTR has increased since I put the large rectangle ad on that place.

3. Choose same colour – Third, make sure that your ad scheme colour is same with your website scheme. The ad background colour should be the same with your website background colour. This implies to the link and the text. Some readers might thought that they are links from your site and not ads. So your chance to earn more money will increase.

Water can burn! Is it true?

12 Comments

I’m not sure whether this video is true or not because it was done without showing who is the demonstrator. Meaning, it might be a fake demonstration. Peoples can create any video as they like as long as it looks real to people who watch it.

The video that you will see here is about a demonstration to make a water burn. The trick is done by using two batteries and sink them in a cup of water for 30 minutes. Then take out the batteries and light the water with fire. And the water is really burn!

After I watched the video, my assumption is, the batteries react with the water and release chemical reaction and produce ions. These ions is flamable and thats why the water is burning when lit up with fire. But, can we drink the water? I guess not.
