Organic impressions: Organic impressions data that is summarized in the Performance report can be extremely valuable. It basically indicates how many times your website was shown in organic search results (not clicked). This can be an extremely important indicator of website SEO health and of whether there are any new issues resulting in fewer search engine rankings. Be sure to monitor this closely, since this is likely tied to overall website traffic.
Organic click-through rate: Click-through rate is important to monitor because it demonstrates what percentage of users clicked each of your search result positions. With improved title tags and meta descriptions and URLs, your search engine result will be cleaner and have better messaging, likely increasing your click-through rate.
