Several updates to this post below! Today at Pubcon Matt Cutts of Google once again promoted the use of autocomplete-type, a new property for web forms that works in Chrome (and possibly other browsers, I haven’t checked).

10 October 2013 by Joost de Valk » - 265 Comments


Today I got a tweet from a user of WordPress SEO who had their site disabled by HostGator, without any prior notice.

After my post about content analysis with the WordPress SEO plugin, which covered the recent updates to that plugin, I got some comments that we should test better, especially because the commenter had issues with a certain slider plugin.

content analysis

We’ve been rather busy with the WordPress SEO plugin the last few days. We did a release yesterday and a quick follow up today to fix a few collisions with other plugins.
