This Day in SEO

2014 May, 20th
Google Keeps eBay at Bay - Let's just start off by saying the days surrounding this were a little chaotic. In less than a week, Payday Loan 2.0 and Panda 4.0 were released, so it took some smart folks to realize eBay's ranking freefall was a manual penalty. Mozcast data showed eBay went from the #6 most visible site in their dataset to #25 and lost visibility by over 70%. A study by Rishi Lakhani revealed nearly all penalized URLs were category pages containing "/bhp/", later known to be acting as footer doorway pages for high value keywords.
This Day in SEO

SEO moves so incredibly fast; it’s easy to forget just how young it is. I’m not even thirty 1 and I’m older than the oldest website. Think about that for a second.

I set out to research the history, evolution and critical milestones of SEO in part just to see what I’ve missed. Although it’s been my job to know SEO from front-to-back over the past seven years, it’s impossible to catch it all. Suffice it to say, from over 150 hours of research and more than 500 events cataloged across 366 days 2, I’ve learned A LOT. Hopefully you can take something away from this research as well. Every day a new event will be posted with a link to more information about it.

The types of historical SEO events include:

  • Search engine launches and key events
  • Important SEO acquisitions
  • SEO patents
  • Famous Google Bombs
  • Major events in internet history
  • Standard-setting legal cases in SEO
  • Search engine algorithm updates
  • High-profile search engine penalties

There are too many websites I used for this research to mention them all, but here are the ones I certainly couldn’t have pulled this off without:
