Well “choke” may be a mite too strong a word. After yesterday’s post on Google Instant Previews & SEO, Organic Optimizer & Veggie Farmer Everett Sizemore pointed out that if GOOG uses your meta description tag as a snippet in the SERPS, then the Instant Preview for your URL does not show the Call Out text.
If this is in fact the case, then site owners are going to have to make a decision as to which will be more beneficial, the targeted snippet showing up in the SERPs or the Call Out. If the people start using these previews a lot, guess which way I’ll be heading.
Update: Procrastinating minds think alike. Check out Everett’s simultaneously published post on the subject.
