Now Manage Custom Search Engine within Google Webmaster Tools

Recently Google has announced that you can now create and manage a Google-powered customized search engine from your Webmaster Tools account only. To do so you just need to click on “Custom Search” Link in Labs Section.

Google will automatically create a default CSE (custom search engine) that searches only in your site. You can get the code to add your new custom search engine to your site. You can make some basic configuration to the CSE or continue to the full control panel for more advance settings.

You can always manage your CSEs from the “Custom Search” link in webmaster tools.

There are lots of advantages of CSEs like

• CSEs can be customized like the look n feel of your site.
• CSEs can improve the user experience with relevant results.
• You can also make money with “AdSense for search” feature.
• Helps in getting better conversions and retention etc.

Google is trying to make things easier and faster, so that you can easily manage your CSE; direct from the Webmaster Tools. If your website still don’t have a Custom Search Engine, try it…because it became more easy now :)

Google is planning to introduce +1 button for AdWords

Today I received an email from Google AdWords Team which was about +1 button integration to my AdWord ads. According to this email you can see a +1 button with your ads very soon. When someone searches on Google, (while signing in his Google Account) he will see a +1 button on your ad, user can click on +1 button to recommend your ad. Recommendations always play an important role in search results. Before AdWords, +1 button is already in use for organic search results & has impacted the search engine rankings as well. Now be ready to see the impact of +1 button on your ads, one possibility is that it may increase your Ad position.

What will be the exact impact of +1 button to ads? We will know once they will be in use.

You don’t need to do anything to use this +1 button for your ads, Google itself integrate +1 button for all AdWords Ads. On the other hand you can add this +1 button to your site, so that the visitors of your site have an opportunity to +1 your site.

You can check the below email which I got from Google AdWord Team.

“Hello,

This email is about your AdWords account XXXXXXXXXX

In the coming weeks, your search results and ads on Google will include a +1 button, which users can click to recommend your ads. You don’t need to make any changes to your account in order to take advantage of them. The final landing page URL of your ads can also appear on the Google profile of any user who +1’s your ad.

Here’s how the +1 button works:
Let’s say you own a hotel in Madrid. Brian had a lovely stay at your hotel last summer. When Brian starts researching accommodations for his next trip to Spain, he searches on Google while signed into his Google account, and sees your ad. He clicks the +1 button on the ad to recommend it to his contacts.

When Brian’s friend Ann plans her trip to Spain, she signs in to her Google account, searches, and also sees your ad – plus the personalized annotation that Brian +1’d it. Knowing that Brian recommends your hotel helps Ann decide where to stay during her travels.

Think of the +1 button as a way for fans of your business to recommend what you offer, for all their friends and contacts to see. By helping searchers see more personal, relevant ads, we believe you’ll see more qualified traffic. You can also add the +1 button to your site to give your customers the opportunity to +1 your site after visiting it.

To learn more about what’s changing and how +1 works, visit the AdWords Help Center.

To add the +1 button to your site, visit the +1 button tool on Google Webmaster Central.

Sincerely,
The Google AdWords Team”

Update: Google has started showing +1 button for Google Ads, see below screenshot.

Create New AdWords Accounts in MCC without Login & Password

Google has rolled out a new feature by which anyone can create new Google AdWords accounts within MCC (My Client Center) without a login and password.  This new optional-login accounts feature will allow users and firms to create AdWords accounts without creating a separate email address and password for the new account.

Google has also provided some tips on how to use this feature:

Creation of optional-login accounts in Google AdWords:
Click on the "Create Account" button within your MCC, then complete the three required fields: account name, time zone and currency. You’ll also see a collapsible link to “Invite another user (optional),” which provides the option to invite a user to the account.

If users want account to have a login:
You can either “Invite another user (optional)” during the account creation process or follow the normal process for inviting a user to an AdWords account: go to the “My Account” tab, click on “Account Access” and choose the link “Invite other users”.

Instant Previews in Google Webmaster Tools

Google has launched instant previews in November, 2010 which shows a quick preview of the search results to user.

Sometimes instant previews look different from what users see on your websites. In this case Google is having some problem in crawling your site. These problems may contain:

• Resources blocked using robots.txt file
• Flawed content served to Googlebot
• Bad alternate content for flash (if flash is not available)

Now Google has introduced a new Instant Previews Tool, using that all webmasters can diagnose their website problems and rectify them.

In Instant Preview Tool at Google Webmaster, webmasters can compare their site as they open in browser (like chrome) and its instant preview. Google recommends using alternative content for flash and silverlight because the webkit that generates both renders does not include plugins.

You can also see a list of problems which Google is facing while crawling your site.

Upload Google Videos to YouTube

In my previous post “Say Bye to Google Videos” I have mentioned that Google Videos is no longer available to watch since April 29 but you can download your videos till May 13.

The downloaded videos can be uploaded to YouTube. Previously Google has not provided any way to directly migrate Google video to YouTube but now Google has provided an “Upload videos to YouTube” option by which you can directly transfer your Google Video to YouTube.

According to Google...

“We’ve created an “Upload Videos to YouTube” option on the Google Video status page. To do this, you’ll need to have a YouTube account associated with your Google Video account (you can create one here). Before doing this you should read YouTube’s Terms of Use and Copyright Policies. If you choose this option, we’ll do our best to ensure your existing Google Video links continue to function.”

If people also want to download their videos from Google Videos, the download option is still there.

Say Bye to Google Videos

Google Videos will no longer available to watch since April 29, 2011. Recently Google, the search giant has sent an email to all users who have uploaded one or more video to Google Videos.

Google is motivating all Google Videos users to upload their videos on YouTube. From April 29, 2011 you can no longer watch your video but you can download your video till May 13, 2011. 

Initially Google Videos was launched to answer YouTube on January 25, 2005, but in October 2006 Google has acquired YouTube for $1.65 billion.  On June 13, 2007 Google Videos search results has started showing videos indexed by their crawlers, YouTube and other hosting services.

Google Videos has stopped accepting new video uploads on May 2009. After that all videos are still available and works as search function. Now Google has decided to completely close the Google Videos by deleting all the existing videos. Even Google has not given any direct way to transfer their Video from Google Videos to YouTube, but they are encouraging all users to download their video from Google Video and upload them on YouTube.

Checkout the complete email which Google has sent to Google Video users:

"Dear Google Video User,

Later this month, hosted video content on Google Video will no longer be available for playback. Google Video stopped taking uploads in May 2009 and now we're removing the remaining hosted content. We've always maintained that the strength of Google Video is its ability to let people search videos from across the web, regardless of where those videos are hosted. And this move will enable us to focus on developing these technologies further to the benefit of searchers worldwide.

On April 29, 2011, videos that have been uploaded to Google Video will no longer be available for playback. We've added a Download button to the video status page, so you can download any video content you want to save. If you don't want to download your content, you don't need to do anything. (The Download feature will be disabled after May 13, 2011.)

We encourage you to move to your content to YouTube if you haven't done so already. YouTube offers many video hosting options including the ability to share your videos privately or in an unlisted manner. To learn more go here.

Here's how to download your videos:

• Go to the Video Status page.
• To download a video to your computer, click the Download Video link located on the right side of each of your videos in the Actions column.

Once a video has been downloaded, "Already Downloaded" will appear next to the Download Video link.

If you have many videos on Google Video, you may need to use the paging controls located on the bottom right of the page to access them all. Please note: This download option will be available through May 13, 2011."

Google Panda Update: An Algorithmic Change to Fight against Content Farms

In February 2011, Google has launched a big algorithmic change which will impact 11.8% queries. Google Says this algorithm will help in reducing rankings of various low quality websites, like sites which use copied content, low-quality content for users and duplicate content. These types of sites are not very useful to be ranked in higher positions. On the other hand various high quality websites which use original content, in-depth information and useful details from the user’s perspective will get better rankings.

This algo update will cause a major change in the rankings of many websites. Google also cleared that this update does not depend on the feedback they have received from Personal Blocklist Chrome extension, but they have compared that Blocklist Data with the sites identified by this algorithm.

In February, this algorithm update was launched for US only and now on April 12, 2011 this algorithmic improvement is launched globally to all English language sites.

Checkout what Google said about this major update:
“Today we’ve rolled out this improvement globally to all English-language Google users, and we’ve also incorporated new user feedback signals to help people find better search results. In some high-confidence situations, we are beginning to incorporate data about the sites that users block into our algorithms. In addition, this change also goes deeper into the “long tail” of low-quality websites to return higher-quality results where the algorithm might not have been able to make an assessment before. The impact of these new signals is smaller in scope than the original change: about 2% of U.S. queries are affected by a reasonable amount, compared with almost 12% of U.S. queries for the original change.”

Google has tested this algorithm and found it very accurate in finding quality sites. If your site has been affected by this update, then analyze various aspects of your site. You can review Google’s quality guidelines to get helpful information about improving your site’s quality.

Google has not provided the names of any websites which went down after the effect of this algorithmic change; Google’s main focus is content farms. Through this algorithm Google will focus on websites which are content farms that uses copied or duplicate content. So if your site is using any content farm, be focused otherwise your site will be go down.

According to Amit Singhal they internally call it "Panda" (name of an engineer among the key guys who made this update possible.) Danny Sullivan of Search Engine Land is calling it “Farmer” as this algo has targeted content farms.

Google Street View Photographs must have 100% Anonymity said Swiss Court

Recently Swiss Court demands 100% Anonymity in all Photographs of Google Street View. Swiss Court says that Google must blur all the faces and licenses in these photos, even if they have to blur them manually.

Swiss Federal Administrative Court has taken a decision on 4th April 2011 and this is one piece of them. Currently company’s automated blurring system blurs 98-99% of faces and licenses. Google has also argued that blurring by hand will be very expensive; also if many other countries followed the same rule.

After this verdict, Google’s global privacy counsel Mr. Peter Fleischer, Shared:

"We have received the court’s verdict and are currently assessing its implications. We are very disappointed because Street View has proved to be very useful to millions of people as well as businesses and tourist organisations. More than one in four of the Swiss population has used it since the service launched in Switzerland. We’ll now take some time to consider what this means for Street View in Switzerland and our appeal options."

This verdict has many other points which must be followed by Google. Formerly Google has faced many challenges and slow downs in other countries.

Algorithm Change Launched: Google’s Fight with Spam Starts

Today the head of Google’s Webspam team, Matt Cutts has announced a new algorithm change for Google. It will help in detecting and reducing web spam from Google’s Search Results. All websites which have low original content or copied content will be affected by this change. They can see a major change in their site rankings in search results.

Cutts mentioned this algo change was approved at weekly quality launch meeting happened on last Thursday and launched this week.

Cutts has announced it on his blog and also posted it at Hacker News. According to his blog “slightly over 2% of queries change in some way, but less than half a percent of search results change enough that someone might really notice. The net effect is that searchers are more likely to see the sites that wrote the original content rather than a site that scraped or copied the original site’s content.”

Cutts said they have re-designed a new document-level classifier, which will easily detect spammy & repeated words. This is the start of Google’s fight towards increasing web spam.

Google Architecture Overview

In this post, I will tell you how the whole Google Search Engine system works.  You can see the complete Google functioning in below figure.

This is a high level Google Architecture; several distributed crawlers are used for downloading web pages from the web. URLserver sends list of urls to the crawlers. Then crawler fetches the web pages and sends them to the storeserver. Then the storeserver compresses the fetched web pages and stores them in a repository. Each web page has a associated id number which is called docID. docID is assigned when any url is parsed from a web page. The indexer part reads the repository, uncompresses and parses the documents. The documents are converted into hits (i.e. set of word occurrences).  The indexer then distributes these hits into various set of barrels.

The indexer parses all the links in web pages and stores important information in an anchors file. The file contains all information regarding a link.

The URLresolver takes data from anchors file & convert relative urls into absolute urls, then turn them into docIDs. URLresolver also generates links database, which is used to calculate page rank of all documents.

The sorter takes barrelts data and resorts them by wordID and create an inverted index.

The sorter generates list of wordIDs and offsets into an inverted index. A program called DumpLexicon takes this list together with the lexicon produced by the indexer and generates a new lexicon to be used by the searcher. The searcher is run by a web server and uses the lexicon built by DumpLexicon together with the inverted index and the PageRanks to answer queries.
