Google always comes up with new idea and this time Google gives a space to the web application developers and they have launched App Engine which is the place where developers can write the code of their web applications. You can store the code of your web applications in the Google File System. It will help those developers who want to expose their products to the users of the Google.

Most of the webmasters use the products of Google and also many services of the Google and therefore it is a great opportunity for the web application developers. The main target of the web application developers is the webmaster and also few people who are using the Google’s services and application very frequently.

Now the users of your web application do not need to build an account to use your application because they can directly access from their Google account. Also with the great start of 500MB storage, 200M megacycles of CPU per day and 10GB bandwidth per day, Google is offering the first 10,000 web application to sign up and use the resources. Now you will get the full information in the Google App Engine Blog.

Lately I have been thinking about to start a blog network and discuss about the matter with many of my clients and colleagues. Starting a blogging network is not a child’s play as most of the bloggers think. You need full dedication and research about the theme of the blog network. The main dilemma comes while bloggers are deciding about the niche or multi-topics blog network. Some bloggers make mistakes by choosing multi-topics blog network because they always think that multi-topics blog network has more scopes than the niche blog network.

But there are some distinct advantages of niche blog network which most of the bloggers fail to realize at the starting. If you are starting a blog network, then it is just useless if you do not promote the blogs. Promotion always comes in the first preference. The most easily noticeable advantage of niche blog network is in the point of promotion. If you have a niche blog network, then you can interlink between the blogs. This is the most effective way of link building and search engine optimization. Also it is the most effective optimization of websites and blogs according to the new algorithm of Google.

And then the profitable of niche blog network comes in the advertising in your blogs. If you have a niche blog networks and all the blogs are of same topics, then an advertising offer from a single advertisers can be advertised on all the blogs because all the blogs are of same topics. But if you have multi-topics blog network, an advertising offer of a blog cannot be post to the other blogs because that particular advertising is meant for only one topic. Suppose, an advertiser wants to do advertising in computer related blogs and all your blogs are related to computer, then you can do the advertising in all the blogs in your niche blog network.

Google Message center is the Google support where you can contact Google for any information about your websites. But previously, only webmasters with verified websites can contact Google through their Message Center. Google message Center is also one of the most important Google webmaster tools. But recently Google has updated their Google Webmaster tools and now they have new Message Center.

Now any webmaster can send message to the Google with the help of Google Message Center. Even if you do not have verified websites in your Google webmaster tool account, you can use Google Message Center to contact them through their support center.

Also Google recently invents new tool to directly report the misuse of Google adsense in the wrong website. Google is trying to block all those adsense accounts with their ads on the “Meant for Adsense Only” websites. Now you can directly report to the Google for any misuse of Google tools or resource and the violation of webmaster guidelines.

Comments on your blog help to score high ranking in search engine. But if it is all spam, then they are useless and nothing to do with them. My blog used to receive more than 100 comments a day but 90% of the comments are spams and just collection of links to unknown websites. It is quite annoying to receive such spams a day and it saps my time to clear all the spams every day.

Recently I made some searches about blocking the spams. Most of such comments are sending by robots and they are not sent by humans. Therefore, there is no use in alexa ranking and it will not help to increase the alexa ranking. Because in actual, there is no visitor count for such visit. Therefore, it is the best move to blog such spams.

Some months back I used a WP plug-in to block all such spams. It is just like testing whether a human is giving the comment or a robot. It is known as Maths spam blocker and in this plugin, visitors must find true sum of two numbers and this task can be done my human only. And now I am using another spam blocker plugin and it is very common. In this an image will be displayed in the commenting field which consists of numbers and letters. You must enter the right numbers and letters in the field. But the maths spam blocker is far better than this image one as the later takes time to display the image.

The question is little confusing and most of the webmasters claim me that adsense is meant for earning by placing ads in your websites or blogs. And Adsense is a PPC program that can give you some pennies for a click placed in your website. But there may be different uses of adsense and I use adsense for checking the traffic of my websites. It provides the dual functions - One for earning and another for the traffic statistics.

I know there are many effective tools for analyzing traffic in a website but I guess adsense is also another useful tool for checking traffic and perhaps it is the most effective one. Well, if you are using other traffic analyzing tools like Google Analytics, then I am not sure whether you will check the traffic statistics every day. But if you are using Adsense, then I am damn sure that you will check every day, may be every minute whether the impression and clicks have increased or not.

There is an inclination towards earning for most of the webmaster and everyone knows that people optimized their websites for some profit or earning money. And if you are using adsense, then there will be some earning and also at the same time you can use the records of the adsense to analyze the traffic statistics of your websites. This is the most effective tool because people frequently check the adsense score and therefore you will have regular records for the traffic of your websites.

Crawlers or robots are the programs of search engine which are released in order to collect information from the web pages in the World Wide Web. You must be wondering how your websites or web pages become listed in Google when you search about it. The mechanism is that the Google Crawler which is known as Googlebot use to crawl all the web pages in the World Wide Web and when it came across a new web pages with new contents, then it collects the information and it will get stored in the data base of Google.

But there are many crawlers and robots which are released by many other programs which slow down the server or sometimes which are not secure for the website because they will get the confidential information. In such situation, people use to block crawlers other than Googlebot because Googlebot is necessary to crawl in the web pages unless your web pages will not be listed in the Google search engine.

Sometimes many webmasters complain for Googlebot can’t access their sites. If Googlebot can’t access your websites, then ultimately your websites will not be listed in Google search engine. Sometimes it may be the cause of not showing of your websites in the Google search engine. If your hoster uses to block many crawlers, then by mistake they might have blocked the Googlebot also. Therefore you must use different crawlers blocking techniques which will not block Googlebot.
