Here is a detailed analysis of what 150 companies do within their IR website to highlight their social media platform. You can compare what your company does for social media to these.
Please note that this analysis is strictly the social media assets which were visible from the IR/Investors section of a company’s website. That means some of the companies listed may have additional social media assets, but they were not promoted or otherwise visible in the IR section.
A good majority of those listed simply had the social media assets on headers or footers which were visible to all pages, including IR/Investors.
To date, we have only seen 1 company with an IR-specific Twitter or Facebook page.
