Google and its algorithms are a constant cause of fervour, interest and fear and for SEO experts and link builders - keeping ahead of the next update is so important.

Web development firms should avoid using the Black Hat SEO techniques to avoid the wrath of Google. They should implement the techniques that comply with Google's modified algorithms.

Search Engines love good content and their algorithms are structured to provide higher rankings to pages with highly relevant and unique web content. SEO Content Writing today is an essential requirement to achieve top rankings for your website. SEO Content Writers make sure that your website content is relevant as well as keyword rich with right keyword density, with keywords placed at the right locations to assist your search engine ranking.

The Dependent Web is dominated by companies that deliver services, content and advertising based on who that service believes you to be: What you see on these sites "depends" on their proprietary model of your identity, including what you've done in the past, what you're doing right now, what "cohorts" you might fall into based on third- or first-party data and algorithms, and any number of other robust signals. The Independent Web, for the most part, does not shift its content or services based on who you are. Who we believe we are in the world is pretty fundamental to being human, and as we bleed our actual identity into our digital one, it's worth recalling that so far, at least, we don't have a system that lets us really instrument who we are online in a fashion that scales to the complexity of true human interaction. I sense an opportunity to create a new kind of social identity..one that is far more personal and instrumented...

According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience and about 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for more information on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible. Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be a primary strategy. With the right design in place, there are many secondary strategies for improving performance such as minification of the code, HTTP compression, using CSS sprites, etc. In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojo compressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yield optimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce any new bugs). The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing its overall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers is gzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier.

Started as a hot topic in Webmasterworld last May 2010, Google has now confirmed the changes in their search algorithm. clickTRUE shares what this means.

An open source framework for building search clustering engines. It can automatically organize small collections of documents, e.g. search results, into thematic categories. Carrot2 can add clustering of search results to an existing search engine. Its algorithms should successfully cluster up to about a thousand text documents, a few paragraphs each.

This is a video of a talk that Lawrence Lessig (Professor, Stanford Law School) gave for an unnamed organization. In his talk, Lessig provides a powerful and piercing analysis on the impact that legal restrictions on the re/use of media resources has on creativity and cultural production. During his talk, Lessig shows some remarkably creative mash-up videos on YouTube to exemplify the kind of creativity/cultural production that is possible through ubiquitous digital media, yet is considered copyright violation, for example, in the eyes of Warner Brothers Music Group. Ironically, the organization that hosted the talk received a notice from Warner Bros Music after posting a video of the Lessig's talk on YouTube, which, according to Lessig's blog, "objected to its being posted on copyright grounds." Warner Brother Music Group has implemented content-id algorithms (i.e., technology that detects the digital "fingerprint" of corporate-"owned" copyrighted works) through media hosting services, including YouTube, FaceBook, and others. When the video of Lessig's talk was posted, it was 'dusted' for fingerprints of WBMG copyrighted works. The detection system identified the soundtracks in the YouTube videos Lessig showed, as materials to which they held copyright. Both the video of Lessig's talk and the blog conversation regarding WBMG's objection are must-see resources.

It's simple with the new "AwesomeBar" this is a completely revamped URL bar in firefox 3. it lets you use the URL field of your browser to do a keyword search of your history and bookmarks. No longer do you have to know the domain of the page you're looking for - the AwesomeBar will match what you're typing (even multiple words!) against the URLs, page titles, and tags in your bookmarks and history, returning results sorted by "frecency" (an algorithm combining frequency + recency).

The latest project by Stephen Wolfram is defined as the first "computational knowledge engine", something capable of answering factual question for you. The Wolfram engine is described as "a proprietary system based on fields of knowledge, containing terabytes of curated data and millions of lines of algorithms to represent real-world knowledge as we know it".

TANBUL adds a pre-processing step to conventional search algorithms to analyze and understand user input for better results

search results can be viewed by date, relevance or a combination of both. Unlike Technorati, which determines a blog's relevance based on the total number of unique links into that blog, Sphere is taking an algorithmic approach.

Changing the zoom level, minimum font size, applying a fit-to-width algorithm, or making other changes may alter the rendition of the test page without this constituting a failure in compliance. The Acid3 test measures some performance characteristics. The test does not attempt to make any comparisons or judgments as to the performance of any hardware used, and should not be used as a hardware benchmark. If the test is run on a slow computer or device, it may run slowly or not smoothly and this does not imply non-conformance.

Autocomplete was one of the first Ajax patterns to come about. We often talk about how it looks, but the how it works part is what really matters. How smart is the algorithm to work out what you are completing against? How long do you go before you kick in to see a result? Does it narrow enough?
