Search Engine Basics

As the Internet started to grow and became an integral part of day-to-day work, it became almost impossible for a user to fetch the exact or relevant information from such a huge web.

This is the main reason why ‘Search Engines’ were developed. Search engines became so popular that now more than 80% of web-site visitors come from them. What exactly is a Search Engine? According to webopedia, a “Search Engine” is a program that searches documents for specified keywords and returns a list of the documents where the keywords were found”.

The New Technorati

Technorati relaunched its site tonight, changing and adding key features. Most notable is an expanded and fresher top 100 blogs list, and a new feature that lets authors post their content directly to the site.

In 2007 Technorati redesigned the look and functionality of its home page three times. Here’s the first. And the second. The last change, made under the direction of incoming CEO Richard Jalichandra, has stayed more or less constant since then.

In the meantime, Technorati has focused on expanding it’s business in other areas, particularly in handling advertising for other sites. Today, only a small percentage of Technorati’s total network traffic of 25 million U.S. unique visitors per month actually visit Technorati.com.

But that doesn’t mean the flagship site isn’t an important asset. And those of us blogging for more than a couple of years can remember the days when Technorati was a key blogging tool, providing, among other things, a high quality real time search engine back when Google only indexed most blogs every few weeks.

Today Technorati still provides a great blog search engine and keeps what many call the definitive Top 100 list of blogs. With the new site, they are focusing more on direct Technorati content (more on that below), and properly categorizing the more popular blogs.

Go check it out yourself, and here’s a rundown of the new features:

Top 100 Blogs:

Top 100 Blogs: Until today, the top 100 blogs were determined based on unique links from other blogs during the previous six months. The top list was fairly static. Now they are focusing much more on recent data within the last month and giving blogs an authority rank between 1 – 1,000. Scoring factors include posting frequency, context, linking behavior and “other inputs.” The result, says the company, is a lot more volatility in the lists as blogs surge up and down.

Technorati is also categorizing blogs among a variety of topics, and providing separate lists of top blogs for each topic. Here’s Business, for example, and Gadgets.

Publish Directly To Technorati:

Authors can now choose to publish content directly to Technorati to gain exposure to a wider audience. This content is highlighted on the top of the Technorati.com home page. For bloggers with a big audience this won’t be attractive. But if I was just starting out with blogging, I’d post some of my content here to gain exposure, and then cross post to my own blog. Each writer has a profile with links to their site and content they’ve written on Technorati.

Search:

Technorati is changing search to give much more weight towards authority and relevance over recency. For highly queried terms like “iPhone,” this cuts out a lot of noise and helps people find quality/definitive content more quickly. Users can also choose to search for blogs relevant to the query or posts elevant to the query, depending on what they are looking for.

Topical Content:

Technorati still shows outside content on a topical basis, too. The light green navigation bar at the top has topics like “Technology” and “Sports.” Content shown on that channel includes stuff directly written on Technorati as well as posts from blogs with high authority for the topic.

Google Experiments With Product Ads In Search Results

Over the last few weeks Google has apparently started rolling out a new set of advertising formats on its search results page, introducing product listings that include price and other details in the Sponsored Links sidebar. For example, a query for “shoes” is displaying a list of different shoe models, their prices, and retailers directly within the search results, as opposed to the the more general text links we’ve grown accustomed to, which lack such information. Google is also apparently testing these ads with photos alongside the product listings for some queries.

Our tipster says that he’s only seeing the new ads in the developer version of Chrome, but I’m seeing them as well in Safari, though some TechCrunch staff aren’t seeing them in any browser. Google is always switching up ad placement and formats in various bucket tests, some of which are browser-specific, so the inconsistency isn’t surprising.

The new formats are likely part of Google’s Product Ads program, which the company announced back in June. The program allows participants in the Google Affiliate Network to place actual product listings in their ads, complete with photos in some cases. Given the limited distribution of the ads we’re seeing, it appears that Product Ads are still in beta.

Google has apparently been testing these ads for some time now — PM Digital noticed similar ads last month.

Twillist Wants The Ultimate Resource For Twitter Lists

Ever since Twitter started increasing in popularity, there’s been a clear need for a more efficient way to manage groups of users than Twitter natively provides. We’ve seen desktop clients like TweetDeck and Seesmic build their own grouping functionality, as have standalone sites like WeFollow. TweepML has even created an open standard for managing and sharing groups of Twitter users. Today, you can add one more to the bunch: Twillist, a dead-simple site for building your own list of Twitter users.

Of course, Twillist’s release comes less than two weeks after Twitter announced that it would offer its own natively supported Lists, which are still in testing with a subset of users. So where does that leave Twillist?

Founder Michael Broukhim (who is also the co-founder of Totspot) says that the site plans to feature heavy integration with the upcoming new Twitter API features, with the intention of becoming the de facto place to create and find Twitter lists. The site will include added features like the ability to see which shared links are most popular in a given list, embeddable lists that you can share on your blog, the ability to collaborate on Lists with friends, and a feature that would let you see which Twitter users appear in the most lists. These features would all certainly come in handy — at this point it’s a matter of where users are going to turn to to find them.

Twillist is easy to use, and can effectively serve as an alternative to Twitter’s web interface. At the top of the page is a box where you can tweet new messages, along with a menu containing all of the lists you’ve created. Clicking one of the lists will bring you to a page that looks similar to your normal Twitter feed, except it only shows tweets from the members of the list. Creating a list is simple too: just enter what it should be titled, as well as their user names (you can add more people to the list later on, too). My only gripe with the process is the lack of an autocomplete function, so you’ll have to make sure you’re spelling each name correctly.

Twillist is quite well done, with a simple but good looking interface and straightforward functionality. That said, it’s certainly got its work cut out for it: along with the aforementioned grouping/list sites that already exist, we’ll likely see quite a few other sites spring up that look to become the authoritative site for Twitter Lists. And this all assumes that Twitter isn’t intending to make a hub of its own, which is hardly a given. But for now, Twillist offers a good way to create and use Lists on Twitter, before they’re actually available through the service

Mobile Advertising Is Shaping Up

WIth the rise of Web phones like the iPhone, Android, Blackberry, and Palm (Verizon’s CEO says that 40% of its new phone sales are such smartphones), mobile advertising promises to be a huge growth area. The Kelsey Group, a market research firm, projects that the mobile advertising market will balloon from $160 million in 2008 to $3.1 billion in 2013.

Of course, that is just an educated guess which will turn out wrong. But there is no doubt that mobile advertising will be much bigger in four years, perhaps even ten to 20 times bigger than it is today. Where will all of that mobile ad money go to? Here I think the Kelsey group is more on target. It projects that mobile search will go from 24 percent of the total mobile ad market last year to 73 percent of the much larger pie in 2013, according to a recent research note put out by Citi analyst Mark Mahaney, which is where I’m getting all of these numbers.

Display ads are projected to go from 13 percent of the total to 18 percent, while SMS ads will decline as a percentage from 63 percent to 9 percent (see charts). So once again it looks like search is going to be the big winner. No wonder Google is so focused on mobile search as one of its major sources of growth.

Think about it. Display ads take up precious real estate on your phone screen and tend to just get in the way and be an annoyance. That’s why most people don’t like them. But when you are doing a search on your phone, you are often looking for something nearby—a store, a restaurant, a dry cleaner. You are more open to ads, especially if they are relevant to your search.

Mobile search is particularly tuned for local search ads. Mahaney writes:

Given the nature of mobile devices, local queries on mobile should, over time, be greater than local queries on the desktop.

Indeed, the Kelsey Group predicts that local searches will rise from 28 percent of all mobile searches in 2008 to over 35 percent by 2013. And as a percentage of mobile search ad revenues, local search is already half. So that is a $1.27 billion market opportunity in four years just for local mobile search.

So who would you rather be: Google or some random mobile ad network shoving display ads into apps and mobile browsers?

New Google Logo Celebrates The Barcode

Google’s new logo is a barcode which, as far as we can tell, says “Google.” Today is the 57th anniversary of the first patent on the bar code. Inventors Norman Woodland and Bernard Silver filed the patent on October 1949, and it was granted, No. 2,612,994 (pdf), on October 7, 1952. The original patent was for a system that would encode data in circles (a bulls eye pattern), so that it could be scanned in any direction (see this interesting article for more history).

The barcode on the Google homepage is Code 128 encoded, which is a standard way of encoding ASCII character strings (ie. A-Z, a-z, 0-9, etc.) into a barcode. It would be safe to assume that Google used their own open source barcode project, ZXing, to generate the barcode. The same library is used in Android for barcode recognition.

The barcode is a technical innovation that has become an often unnoticed, yet essential, part of modern day life. The format is a global standard, where a scanner from any manufacturer can interpret almost any conforming barcode from anywhere (assuming it can interpret the encoding format – which is UPC in the case of products, and Code128 or something else for other applications, depending). The barcode is a great example of why uniform protocols and standards serve a greater good for everybody, and the same lesson certainly applies to the web.

We had to double check that the barcode in this instance was correct (some of the geeks here insist the barcode isn’t 100% correct), since Google has previously messed things up when they try and talk geek dirty.

Google regularly changes its logo for holidays and other special events. Here’s their 10th birthday logo from last year, for example. More recently they celebrated Gandhi’s birthday. Google hosts some of their holiday logos here, and fan created logos here.
