As you can see in the chart from MarketingSherpa above,
one fifth of respondents called SEO their “strongest tactic†for ROI – up 3 percentage points from 2007 to 21%. Also, “good ROI†jumped 2 points to 38%. More importantly, we see a 6-point drop (28%) in those who call the results of SEO “hard to gauge.â€
Positive findings in paid search as well as shown in the chart above. I’d say, “thanks to web analytics!”
