Some basic tests to check your website for accessibility

Written by Trenton Moss


The Disability Discrimination Act says that websites must be made accessible to disabled people. So how can you check that your website is up to par? There are a number of basic tests you can make to address some ofrepparttar main issues. The following list includes guidelines that provide a good start in increasing accessibility to disabled people:

1. Check informational images for alternative text Placerepparttar 118738 cursor over an informational image, for example,repparttar 118739 organisation logo. Does a yellow box appear with a brief, accurate description ofrepparttar 118740 image? For users whose browsers do not support images, this alternative text is what they will see (or hear) in place ofrepparttar 118741 image.

2. Check decorative images for alternative text Placerepparttar 118742 cursor over a decorative image that does not have any function other than to look nice. Does a yellow box appear with a description ofrepparttar 118743 image? It should not. There is no reason for users whose browsers do not support images to know that this image is there, as it serves no purpose.

Be careful though as this is not a foolproof test. If a yellow box does not appear, this could mean one of two things:

•The alternative text ofrepparttar 118744 image is assigned a null value, which means that it will be ignored by browsers that do not support images. This isrepparttar 118745 ideal scenario. •The alternative text ofrepparttar 118746 image is simply not set at all, which means that users whose browsers do not support images will be alerted to its existence but will be unable to find out what purpose it carries – something which is very frustrating! This is certainly notrepparttar 118747 desired outcome.

3. ‘Listen’ to any video or audio content withrepparttar 118748 volume turned off If you turn your speakers off, you are clearly unable to listen to, or follow, any audio content. This situation is faced by a deaf person on a daily basis. Ensure your website supplies written transcripts, so that deaf people can understandrepparttar 118749 message that your website is conveying.

Did Yahoo!'s Rising Storm Finalize a Shift in AskJeeves Colors?

Written by Ross Dunn


Based On An Exclusive Interview With Ask's Jim Lanzone. It appears that Yahoo!'s bold and less than brilliant foray into " Looksmart-like " paid inclusion may have beenrepparttar final nudge that AskJeeves needed to shut down their paid inclusion program, Index Express (not Index Connect which is Inktomi). This significant shift of AskJeeves away from their 18 month-old paid inclusion program appears to be a timely distancing fromrepparttar 118737 pending storm coming to Yahoo! after it announced its new Site Match system.

Why did AskJeeves shut down their Index Express service? To get torepparttar 118738 bottom of that I spoke today with Jim Lanzone, VP of product management at AskJeeves. First I should mention that he very carefully noted he does not believe there is a 'dark underbelly' to monetary search engine inclusion models. He noted Yahoo!, Looksmart, and many others when he emphasized that. When we concentrated onrepparttar 118739 topic ofrepparttar 118740 cancelled Index Express service he explained that AskJeeves came to this decision based on two elements;repparttar 118741 first was technical and attributed to significant testing of their paid inclusion model,repparttar 118742 second was entirely monetary. The testing revealed that the differences between a page submitted via a trusted feed (xml feeds via Index Express customers) and a page indexed byrepparttar 118743 Ask spider were so significant that attributing proper relevance was very difficult. As a result, users, advertisers and Ask technicians alike were finding Index Express submitted pages ranking in odd places; sometimes ranking inordinately high or low. The second reason focuses on what is likelyrepparttar 118744 shareholder's bottom line;repparttar 118745 model was “not a very good monetization vehicle."

Willrepparttar 118746 AskJeeves database take a big hit with this change? This is difficult to say but considering that Jim Lanzone said 30,000 ofrepparttar 118747 2 Billion pages indexed in Ask were Index Express pages there could be a miniscule drop in Ask's database size. Other than that I cannot foresee any significant negative impact. In fact, I only see a brilliant move here since paid inclusion models will undeniably be underrepparttar 118748 FTC and SEO microscope forrepparttar 118749 next few months, what with Yahoo!'s 6 web properties adapting to it with gusto.

Note: It is important that our readers understand thatrepparttar 118750 paid submission process at Ask Jeeves is still active and recommended byrepparttar 118751 staff at StepForth. According to Jim Lanzone,repparttar 118752 sites that are submitted via Site Submit will be indexed within one week and then repeatedly 2 times per week. Considering that sites which do not pay submit may not be found or may only be indexed sporadically, this appears to be a very worthwhile service.

An Inside Glimpse of AskJeeves

Right now AskJeeves has a search engine that, in my opinion, is truly impressive. The natural language processing and wealth of quality information in their database has become so good that searching by query actually provides relevant results 90% ofrepparttar 118753 time! This is a vast improvement overrepparttar 118754 original natural language system that Ask had in place just a year ago. When asked what made AskJeeves so different from its competitors, Jim answered decisively that it was Ask's search technology that put it in a category all of its own. Whyrepparttar 118755 technology? Well Jim argued thatrepparttar 118756 intuitive query performance ofrepparttar 118757 search andrepparttar 118758 system's ability to reliably show onlyrepparttar 118759 experts in every field was Ask's ‘secret sauce'. When I personally put this torepparttar 118760 test I had to agree that atrepparttar 118761 very leastrepparttar 118762 top results I found were relevant and spam-free… an impressive characteristic. What I must enter into consideration, however, isrepparttar 118763 considerable difference in database size in comparison to Ask's competitors; Ask has only 2 billion pages, whereas Google claims a 6 billion count and Yahoo! over 4.5 billion. In this case size does matter… especially when you consider trying to filter twice to three times more content.
