Alexa Site Speed

Comment on WordPress SEO Tutorial by Héctor.

Hi Dave,

When I check my site in Alexa, I notice this note:

“Slow (1.989 Seconds), 67% of sites are faster.
Note: Slow sites may be penalized by search engines.”

I started addressing this and my first stop is at the Markup Validation Service, when I check it out, the report suggests there are 7 errors. I checked your site too (yeah, trying to copy the master from time to time)… and I noticed some errors are also reported at the same spot (Facebook Social Plugin). I was wondering whether you could give me some ideas on how to troubleshoot it (beyond disabling the plugin, which I do not want to).

Thanks
Héctor
P.S: If you have any comments on how to improve the speed of the site, it will be very welcome.
