Hello I have a doubt. Are images with text in the alt attribute accessible at the same level as images without alt tab text in which the text is added with html so that it seems that the text itself is part of the image? I just want to know whether the second choice is better than the first for search engine optimization or not.
In conclusion, I would like to know whether it is worth it or not to extract the text from images like these leaving the alt tab attribute content as "" and adding the same text on the same position they were lying on the original image but this time with html, to improve search engine optimization. Thanks
tedster: As to what the search engines will use, that is always a question worth watching and testing. Right now the alt attribute is what affects ranking, from what I can see, and the title attribute is not used as a signal. And that makes sense, because it is what non-visual browsers and screen readers like JAWS will be "reading" aloud.
"Content is "equivalent" to other content when both fulfill essentially the same function or purpose upon presentation to the user."
The above quote comes from the WCAG (Web Content Accessibility Guidelines) and refers to attributes that are utilized to present alternative content, the alt attribute being one of those.
The title attribute is an advisory element. It is typically invoked on hover and provides advisory information. I use them quite a bit on table headings in tight confined areas where we have to use brevity in visual text.
I believe that all content that is left after stripping markup is utilized to some degree. Content that resides in title attributes would be part of that. But, it's not to be used for what some might think. If you replicate in the title attribute that which surrounds it textually, I think it just negates itself. You also bring in the stuttering effect. My understanding is that certain software for accessibility allows the user to listen to advisory attributes, the title being one of them.
WordPress realized their users were stuttering out of the box and they have a Plugin to stop the madness! ;)
