Google insight vs Yahoo clues


Both  Google Insight and Yahoo Clue is for SEO purpose.

Google Insight is a search database that can filter on search terms like location, time, and category and give you a graphical representation such as interest over time of search volume, top search terms, and related. It is a product similar to Google Trends that will enable you to examine a certain niche in detail.

It will help you decide which advertising method works best or find out when people are searching seasonal items — the site gives ski resorts as an example.

It can also tell you how competing brands or locations are doing and what markets may be developing for your product or service.

Example:

Yahoo! Clues is a new beta service that gives you a unique “behind the scenes” look into popular trends across the millions of people who use Yahoo! to search each day.

With Yahoo! Clues, you can discover and compare trending information for search terms of interest to you, or explore popular trending search terms on Yahoo!

You can see search volume charts, demographic graphs, maps, or even related searches specific to a demographic group. We’re also experimenting with an interesting feature called “Search Flow,” which offers a unique look at people’s search patterns and the next most probable search term people try after searching for a query.

goo.gl Advantages and disadvantages


Nowadays most of us eager to use google’s url shortening service goo.gl including me. Previously I have used bit.ly. In terms of usability and uptime speed it is fine but they have missed some features.

I have listed some features, is anything missing please add it in comments

Disadvantages:
1. Duplicate links
If i’m creating short link for same url more than one time it results different short url for a same page/url
2. Can’t remove from listing
goo.gl displays the list of short urls we have created, But there is no option to delete/remove/hide from listing.
3. No option to create Custom url
It will be nice if they give option to create custom short link then they can share are remember easily.
4. Missing API for create short URL
Currently they don’t have option to create short urls through API. In this case I prefer bit.ly . I think they will have API support soon

Advantages:

1. No need to have separate login account
We can use the same google account
2. Click count
We can view click count by location, OS, browser, timing, referral url.
3. QR code
A QR Code is a specific matrix barcode (or two-dimensional code), readable by dedicated QR Barcode reader and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data.

Google’s new Image format webP


Google always interested in speeding up the webpage. They have launched Google Chrome one of the fastest webbrowser. Now they are implementing new image format WebP. Google says from this image format they can reduce the image size by 40% without affecting the original quality of a image in JPG.

A WebP file consists of  VP8 image data, and a container based on RIFF. Webmasters, web developers and browser developers can use the WebP format to create smaller, better looking images that can help make the web faster.

Google's WebP image format

Google has already successfully implemented its own video format WebM for all its YouTube videos in addition to H.264. What does this all mean to web designers and website developers? Well for one thing, they need to make sure that their websites are compatible to these formats in the coming years.

hot pot vs foursquare


Google releases its new location based product to compete popular place sharing service foursquare.com.  We can say google’s hotpot is a clone of foursquare.

Smartly, Hotpot pushes Places, getting business owners to claim their free listings to help Google build their efforts in the online Yellow Pages space, while using social networking to build reviews for their products.

You can add reviews on your smart phone by using Google Maps for Mobile, so they have the mobile thing included as well. And Hotpot also has its own Twitter account to friend people – it should not be long before there is a tie in for users to Tweet their reviews.

“More than 20 percent of Google searches now have a local intent, and it’s clear that finding information about what’s immediately around you is important…. With Google Hotpot, we’re excited to take local search to the next level by making it more personal with recommendations powered by you and your friends,” the Hotpot blog stated.

Advantages of hotpot Over foursquare

Other than the concept in hotpot we can login to the account easily by using same gmail account.

hotpot allows you to access in mobile apps via google maps on antroid .

Google Places – These are the 50 million places around the world for which we have rich details.

The places you like – When you rate places you like, we’ll tell you about other related places you’ll love. I love my favorite neighborhood restaurant in Noe Valley, Firefly, so when I rate it 5 stars, Hotpot will try to recommend other places for me in the city with simple, homey food such as Home restaurant.

The places your friends like – Share your ratings with your friends and see the places they’ve recommended. I’m planning a trip to Barcelona for the holidays and my friend Bernardo is a local. With Hotpot, I can see his recommendations when planning my trip on Google Maps, or when I’m in Spain using Google Maps or Places for Android.

Their main forms of revenue today are engagement ads and self-service ads.   Already 2 million sites included facebook connect.

 

About URL Shortening Service


URL Shortening Service is to turn long links into short ones have suddenly come into their own.

Universal Resource Locators – URLs, or web addresses – looked really simple when research physicist Tim Berners-Lee thought them up in 1989. Then database-driven content turned URLs into lengthy strings of gibberish.

Enter the redirection services. They are just huge, simple databases. They trade on the combinatorial power of the alphabet plus the 10 digits: with a “redirection” link just one character long, you could represent 36 possible URLs. Use two, and you have 36 squared, or 1,296; by the time you’re using six characters, the possibilities are in the billions.

Small is beautiful too

So: take a huge, 120-character URL and feed it into a dialog box on the shortening site. It first looks in its database to see if it has processed that URL before. If it has, it gives you back the previous answer. If not, it generates a new shortened URL on the fly. Put the shortened URL in your browser’s address bar, and the site looks in its database for the matching URL and redirects you there.

The first of today’s URL redirection services were set up in 2001: MakeAShorterLink (masl.to) – which has since been bought by the biggest such service, TinyURL – and SnipURL.

Until the beginning of last year, URL redirection services saw steadily though modestly growing traffic. In March 2004, Wired reported that TinyURL was generating 8,400 shortened URLs a day and 80m page views a month. The Wayback Machine shows that by 2005, TinyURL had shrunk about 5.5m links. In August 2007, it was 42m. Now, it’s 90m.

It was the arrival last year of Twitter, the microblogging site, that transformed redirection sites from merely useful into absolutely essential.

Twitter is blogging for the SMS generation. It enables the “smart mobs” Howard Rheingold wrote about in his 2002 book, Smart Mobs: The Next Social Revolution.

Rheingold has said he’s hooked on Twitter because it’s “a rolling present”.

Marshall Kirkpatrick, a consultant based in Oregon and lead writer for readwriteweb.com explains:”There are lots of other circumstances where shorter URLs might be a good idea, but on Twitter you have to have them because of the 140-character limit.”

The experience of Shashank Tripathi, founder of SnipURL, backs this up: traffic through SnipURL has nearly tripled since Twitter went live. There are as many as 70 of these services, all free, all with increasing traffic. Some offer added features such as the ability to track how many people have clicked on your link or an open programming interface (API) so developers can build the service into the applications they write.

One problem for all these services is dealing with spammers, for whom hiding a link’s ultimate destination is useful for bypassing spam filters and trapping the unwary into visiting their sites. Letting users preview sites is one antidote; another is acting quickly to disable bad links when they’re reported.

Another problem about increasing traffic, however, is: how does a free service scale? Andrew Chapman, one of the four people behind UK-based qurl.com, is not convinced it’s possible to turn that traffic into money.

“This kind of service, people expect to be free,” he says. Qurl shortens links to a five-character string and also allows users to pick meaningful words. He says: “I thought originally I would monetise that as a premium service, but I never got around to it.”

TinyURL does have Google Adsense on its home page, but much more than that, says Chapman, “would just annoy people, and then they’d go to another service. It’s part of web culture that lots of things are free to use.”

In mid-July, Twitter bought Summize, an independent search engine, just for Twitter. Can the acquisition and consolidation of URL shortening services be far behind? And nearly simultaneously, Summize’s early investor, New York-based Betaworks, launched its own new URL shortener, bit.ly.

Betaworks’ chief executive John Borthwick says that while it’s not expensive to build a URL redirection service, it is expensive to “build one that scales, grows, and keeps billions of URLs”. Until now, he adds: “This market has been made up of developers who’ve needed something to solve this problem so they put out a solution.” Betaworks built bit.ly because, he says, “nothing was quite open enough or scalable enough”.

Betaworks had expected to launch bit.ly quietly and add to its functionality over the next few weeks to make it clearly different. Instead, people leapt on it.

Thinking of linking

Where TinyURL uses a single server to generate shortened URLs and an algorithm that generates each new one based on the existing count, bit.ly uses a distributed index and multiple servers: it picks the next URL randomly and then synchronises the index tables across the servers. The chances of collisions are remote now because the service is so new, but “we’re thinking hard about how to deal with it when we have billions,” says Borthwick.

An important distinguishing feature: bit.ly keeps copies of the destination pages, eliminating one of the key problems with the older services: “link rot”.

Bit.ly is also running the saved pages through Reuters Open Calais API, which, says Kirkpatrick, lets it “analyse content and semantic terms”. Identifying the concepts and subjects of interest and matching those with geographical data parsed through another API means that “if bit.ly ever got to TinyURL status it will have a pretty rocking database of machine-readable web pages”.

What Kirkpatrick is talking about is taking search to a new level: a human-selected collection of pages that matter to people. And you don’t have to rely on active tagging or pay for all that relatively expensive indexing.

Kirkpatrick concludes: “I always assumed that’s how somebody was going to make money through one of these services because they’re seeing all this traffic come through – links that are obviously important to people.”
