Ovewr at Performancing a new infographic about search engines has been released by the Infographiclabs team. After the detailed Google History graphic we recently published, this new infographic takes a look a the different search engines there have been in the last 20 years. A trip down memory lane for everyone who’s been online longer than 5 years now. You can view the complete infographic at Performancing.

We’ve already reported that Microsoft’s Bing search engine had started indexing prominent Twitter users’ tweets, but now Twitter has announced official support for indexing of tweet content by both Microsoft and Google.

Microsoft has announced that it now has access to the entire public Twitter feed and have launched a beta of Bing Twitter search (US only at present). read more

You probably have noticed that many blogs (including this one) use LIJIT as their search engine provider. Well now the search specialists have unveiled a new tool: Blog and Social Content Search Gadget for Blogger. read more

Twitter just rolled out their new front page, which was known to come. I’m a bit ambivalent about it, mainly because it seems to follow all of the design trends out there at the moment.

Anyway, the new front page features search from the front as well as a selection of trending topics, which is good. The reason for this is, well, I’ll let Biz Stone tell it himself:

However, demonstrating the power of Twitter as a discovery engine for what is happening right now through our Search and Trends often awakens a sense of wonder which inevitably leads to a much more compelling question, “How do I get involved?”

So what’s the verdict? read more

While Google may be looking into making Twitter searchable, Microsoft has already started implementing its own real-time search into Bing.

At present it’s a fairly limited offering, indexing “some of the more prominent and prolific Twitterers from a variety of spheres”.

It seems that you can only search for the latest tweets from certain people who have been indexed, using syntax such as “[name] Twitter” or “[name] Tweets” or “@[name]”.

As a concept, it’s a good start though I’m not interested in using any search engine to find anyone’s latest tweets — I use Twitter or one of its desktop clients for that. read more

Not to be out done by the Fail Whale, Facebook is launching new real-time search functionality that will allow members to look for information located in the links, comments and photos and videos of registered users. read more

File this one under ‘we knew it was coming.’

There are unconfirmed reports that Google will build a search engine that will allow users to better filter results – similar to the process currently used for a Google blog search.

With a growing number of people relying on Twitter (and other micro-blogging sites) for the latest news and trends, a universal search solution is desperately needed.

It is probably safe to assume that the priority of search results will be determined by Twitter prowess, including the number of tweets and retweets you have, the frequency in which you post, current events, frequently used keywords, and, of course, the number of followers you have.

We already know that Google is crawling Twitter, now we just have to sit back and wait for the other shoe to drop.

As if you needed another reason to become a more active Twithead!

The microblogging service Plurk is living a quiet life in the shadow of the all-powerful Twitter. That doesn’t mean that it isn’t being developed, in fact, Amir Salihefendic just announced the addition of realtime search to Plurk. Yes, Twitter has already got that, but Plurk takes it one step further by indexing every plurk ever sent (50 million or so), as opposed to Twitter’s past 2 months. Nice.

Media companies with vast budgets who produce “professional content” should get some preferential treatment from Google, according to a weekend report in Advertising Age.

I’ve avoided using sensationalist headlines because I think there’s value in looking at the underlying principles here.

It would be very easy for me, as a blogger, to have a knee-jerk reaction against those calling for Google to favour certain brands, particularly as one content executive described bloggers as “parasites off the true produces of content”. read more
