I would like to use custom attribute inside H tag for example

<h3 mydata="1">header</h3> 

Is this style is good for SEO ?

Thanks

回答1:

This attribute will cause your HTML to stop validating because mydata is not a recognized attribute for the HTML DOCTYPE.

Instead, use data- attributes to store data. These are not parsed by search engines and have no effect on the SEO value of your page.

For more information, see: http://www.w3.org/TR/html5/elements.html#embedding-custom-non-visible-data-with-the-data-attributes

Im not sure about SEO, but you should always do it in the format:

data-[attribute]

this is the prescribed "HTML5" way of doing custom data attributes and it works on non-html5 browsers. It also is useful when getting data using jQuery -> $(selector).data().

If you want to store data in attributes then check-out HTML5's data-attributes: https://developer.mozilla.org/en/HTML/Global_attributes#attr-data-*

You can safely use data-attributes as far as SEO is concerned.

Your attribute would look like this:

<h3 data-mydata="1">header</h3> 

回答4:

"mydata" wouldn't be valid HTML. So no, not a good idea.

Use data-attributes instead.

SHORT Answer YES, is valid SEO. SEO is all about search engines friendly URL's.

Anyways your HTML will not be valid. Use data-attribute instead, as suggested above. If you're a picky HTML developer as I am, you can always validate your HTML using this tool:
