A core part of any marketing campaign is measuring its effectiveness, and it’s this exact reason that has many wary of SEO, precisely because it’s so difficult to define success. However, there are metrics that can give you an edge and a better idea of the return on investment of SEO. Organic conversions are an extremely effective way to examine the ROI. Moreover, despite being measured differently, organic conversions are the best way to convey to executives the effectiveness. Page 1 keyword growth is another metric that is effective and keyword research is a critical step before optimizing content for SEO. Including overall search volume increase is a supplementary statistic that is also effective. Finally, organic traffic and clicks can show that SEO’s long-term strategy is taking hold, while it’s difficult to tie directly to this, benchmarking before and after is a good indicator.
