This document summarizes research on the relationship between social sharing, organic search rankings, and click-through rates (CTRs). It finds that while social shares do not directly impact rankings or CTRs, there are positive correlations. Content with high social engagement rates, rather than just shares, tends to see above-average CTRs and better organic search performance. The document also outlines "unicorn CTR hacks" like testing headlines, advertising content, and remarketing to drive social engagement and search success.
