Why not to do April Fools pranks online
Take, for example, a couple days ago. We didn't do anything special for ToolBarn. A couple of our competitors did "Funny" things. We saw one of our best Sunday sales totals ever. For that, I've got to thank them.
But sometimes the joke bites back at you for days afterwards. For example, today's #1 result for "seo blog" on google.
Yes, Mr. Cutts did a nice "Hacked" theme for the day, and two days later we're seeing the Hacked SERPs. You'd think he would have known enough to cloak that so his SERP description didn't lessen his credibility. All in all, not the best planning I've seen.
