March 31, 2010 by bharath

Unlike most of the other browsers like Mozilla Firefox, Internet Explorer or Opera, Google Chrome doesn’t automatically gives a quick way to subscribe to RSS feeds in a web page with a single click.

If are very much used to the other browsers then you might be feeling inconvenient in Google Chrome due to lack of this quick RSS feeds subscription feature.

Well, if you are just worrying about this missing RSS subscriptions support, you should look at this great extension “RSS Subscription Extension” developed by Google.

This extension auto-detects RSS feeds on the page you are reading and upon finding one will display an RSS icon in the Omnibox, allowing you to click on it to preview the feed content and subscribe.

Also the extension has 4 predefined web-based feed readers (Google Reader, iGoogle, Bloglines, My Yahoo).However you can add any web-based feed reader of your choice to this list.

Here’s how any website offering RSS feeds will look like after installing this extension.Observe the RSS icon in the Omnibox.

Google Crawling, Canonicalization and Indexing Explained

March 30, 2010 by dennis

Have you ever noticed that your blog posts are indexed in blog search in few minutes but it doesn’t come so fast in the main index? Why some of the posts are indexed faster than some of the other posts? Are sitemaps really helpful for indexing? How can you get your posts indexed faster?

All the questions really hit us much of the time. The answers are explained here.

In this post we will see:

1. The Main Difference between Indexing and Crawling

2. Main Use of Sitemaps and pings

3. Which blog posts are indexed faster

4. Google Canonicalization of the Crawled Contents

1. Difference between Indexing and Crawling

When you post an new content in your blog, Google may crawl your post but may not index it in the main index. In case of blogs Google blog search may crawl your new URLs within few minutes but it may not to the main index.

Even though Google crawls your post it doesn’t mean that the post will be indexed. Google follows certain standardization process according to its policies that the crawled content is first analyzed for quality content and then sent to the main Index. You can read further how this standardization is done below. So crawling and Indexing in Google are different.

2. Main Use of Sitemaps and pings

If you think that by submitting your sitemap to Google or by pinging to Google your posts will be definitely indexed. Google uses the sitemaps submitted to it to crawl the content, new URLs and finds out the quality content to get them indexed in Google. Google does not guarantee that by submitting your sitemap your content will be indexed. Again the Canonicalization process comes in to index the contents.

3. Which blog posts are indexed faster

This is really a big question mark. Well explaining according to Google, posts or contents from well knows blogs(popular ones) and which have good quality contents will be indexed faster. Popular blogs with good contents will be will be frequently crawled and index. So if you want your posts to get indexed faster, then get your blog well known and post good content.

Now your question will be what is good content! You can find the answer below.

4. Google Canonicalization of the Crawled Contents

Google has its own set of rules and policies that are applied to the crawled contents and decides whether to index the content or not. This process is the Google Canonicalization process which is done to produce relevant and quality results. So any blog post with good content will pass this standardization process will be indexed in a short duration of time. As far as we have seen, good content is the one which has a unique style and which has more keywords that are searched frequently in Google. But the process of Canonicalization frequently changes as the policies change, so we cannot define which are Good posts permanently as far as Google is concerned.

So you have learnt that in order to get your contents indexed faster you need to:

Popularize your blog
Produce Good and Quality content
Use relevant Keywords
Have a Unique Style of your own (Do not Copy and Paste)

You can watch Google explaining the details of blog indexing below:

[How-To] Find Suspicious Activity In Your Gmail Account

March 28, 2010 by bharath

Gmail is the popular mail service that is being used by huge number of users worldwide.Google (Gmail) always warns users about keeping a stronger password for their Google account, since if the hijacker manages to get your Gmail password, he can virtually access all the Google services associated to that account.

The point to make note here is that the mail services are the most hugely attacked services by the Hijackers/ hackers around the internet.So it is all our responsibility to ensure more safety to it by setting up a stronger password and not revealing this password anywhere else and to anyone else.

But sometimes, your account gets hijacked even without your notice and all your private data gets exposed.Well, they always say “Prevention is better than cure” which aptly sits here.

If your account gets hacked, there won’t be much details available so as to find who the real culprit is.However, Gmail team has come up with an option to display though which agent your account has been accessed (ex: browser), along with the country from where it was accessed (IP address with country name).

To see from where your Gmail account has been accessed in the recent few days, go to bottom of your Gmail inbox, where you can find “Last account activity” section.Click on the “Details” link to see IP addresses of the computers from where your account has been accessed.

gmail last access details

If Gmail finds any unusual/suspicious activity in your account (meaning that somebody is illegally accessing your account possibly accessing from a country where you have never been !!) it warns you change your password immediately (see the screenshots below).

gmail suspicious activity warning

So if you are at anytime concerned over your Gmail account being hijacked by someone, probably this is the first thing you should do : Open the recent activity details accessible from the bottom of your Gmail page and check out for any suspicious access of your account.

How many of you have seen “Suspicious activity” alerts in your Gmail ? Let us know through comments..

Google.cn Is Over, Redirects To Google.com.hk (Hong Kong)

March 23, 2010 by bharath

This is breaking news coming right from the G-folks : Google has decided to redirect Google’s Chinese web users of Google.cn to its Hong Kong site Google.com.hk starting from today.

This has been posted in Google’s official blog.

earlier today we stopped censoring our search services—Google Search, Google News, and Google Images—on Google.cn. Users visiting Google.cn are now being redirected to Google.com.hk, where we are offering uncensored search in simplified Chinese, specifically designed for users in mainland China and delivered via our servers in Hong Kong.

This is the Google.cn’s cached page as seen from Bing’s cache.

This is the new Google.com.hk site where the Google.cn users being redirected:

Also Google is predicting that at any moment, the Chinese government may stop access to its services.

We very much hope that the Chinese government respects our decision, though we are well aware that it could at any time block access to our services.

Hence to keep its users notified about any blockage of Google’s services, it has set up a new web page (China service availability), where one can see the status report of various Google’s app services.

Google is also worrying about the safety of its employees in China, which is clear fro this statement:

Finally, we would like to make clear that all these decisions have been driven and implemented by our executives in the United States, and that none of our employees in China can, or should, be held responsible for them.

This up gradation of speed came into light when one of the customers who wanted a new connection when contacted the Beam Cable agent, offered him with up to 768 kbps speed for Rs 600 (INR) per month whose official speed is 256 kbps.

Though the speed upgrade is not officially confirmed, the increase in speed is almost confirmed with all the users of Beam Cable Broadband known to us.

The speed upgrade is to be as follows:

1000	1Mbps	2Mbps

*this is a report from the users which is not officially confirmed

The above given packages speed are confirmed by the users, other packages speed could not be confirmed currently.

A User Survey by Techrena dot Net Reports:

Rs 600 Package user getting 75-85KB/s Download Speed
