Click through rates: Searches using terms that denote high purchase intent such as product or brand-specific keywords will get more clicks than organic results. The advantage of paid search can clearly be seen in the Internet retailers MarketLive Performance Index data. For the year 2013 as a whole, PPC accounted for 36.5% of search traffic but an outsized 47.9% of revenue from search.
Additionally, knowing how your SEO is performing can help you make the necessary changes over time to keep your rankings high. Look around for a keyword tracking tool to help you track how your SEO is performing. It’s typical for your ranking to fluctuate from week to week and even day to day. Look for a general upward trend from month to month that shows that your efforts are successful.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
