Social Media icons and their Prominence
Your social media buttons should be prominent, but in most cases they should not scream “please like this page.” This comes, in large part, down to sizing. Make your social button selection large enough to be clearly and decisively visible, but not so large as to overpower the content. Avoid using too many social media buttons. This makes the page looks crowded and adds a barrier by making the user actively look for the appropriate button. An overabundance of social media icons can also significantly slow down page loading times, which can have serious consequences for both user engagement and SEO.
I generally test this on my websites for around 2 weeks, reviewing which areas give the best results.
