I have the Premium version of W3 Total Cache, with the Genesis Framework Extension. When I google a given keyword, Google returns the wrong title, breadcrumb and link to URL, but the right description (the one to the post title that was expected to show up in the results, but didn't).
For example, I have an article titled "Cefaleia Rebote - Uma Análise Completa") (in English, "Rebound Headache - A Complete Analysis"), and the URL to the post is http://www.enxaqueca.com.br/blog/cefaleia-rebote. Now, when I google the key phrase "cefaleia rebote" in my Safari browser, I get the result for the title, link and breadcrumb to a totally different article about chocolate and migraine, whose title or content doesn't even carry that key phrase (http://www.enxaqueca.com.br/blog/chocolate-enxaqueca/), along with the description for the correct post. The same search in the Chrome browser will return the correct result (title, breadcrumb, description and URL).
I just turned off the Genesis Framework extension altogether as a precaution. I had enabled caching of the wp_head in that extension. Any thoughts, please?
