Review your current Search Engine Listing Positions. You want to know where your site stands now and how you want it to grow across your product base and chosen keyword targets. Popular kinds of reporting tools include search engine ranking positions, which help you to gauge your visibility in the search engines and also to determine if your listings are contributing to your traffic and sales. One important item to review is 'traffic vs. conversion rates'. If you are receiving high visitor counts, but a low sales conversion rate, then you need to focus on the on-page aspects of your SEO campaign because something is not working well on your site checkout process and it may be causing your visitors to bail on the purchase process. The issue can be your your server settings, checkout process, your shipping rates or a combination of other things that need to be determined by an experienced ecommerce marketing professional.
