Thanks for the kind words…but more than that, thanks for both the quality of your data AND the artistry on the infoGraphic too!

Can’t wait to see the next ones…and I go to your own blog every morning to see what else comes from Greenlight…great stuff lads!

Thanks very much for the mention. Regarding the missing tactics you mention, I’d just like to add for the benefit of your readers that the chart doesn’t plot “tactics”, or even strategy, so much as broad algorithmic factors that we as SEO’s need to be concerned with. Of course, within each of those factors are numerous tactics, some of which are mentioned in the timeline. But while I did consider adding a “strategy and tactics” overlay to the chart as well, plotting the time period in which, say, reciprocal linking was a widely used and effective link building strategy, in the end the infographic just became too busy!

That said, I appreciate and look forward to any and all feedback that you or others care to give.
