Welcome to the Q&A Forum

Hey there! This is a fantastic question. I would continue the process of posting your images to social as it will improve the probability of people finding you either way. I know it's tedious but if you find that you get a presence in image search on your site and in Google with both, I would keep it up. You can create a custom action in photoshop where you just take an image into that and it'll brand it with a few clicks (you may have been doing that already). I commend your diligence on doing both as an A/B experiment. I would love to know if these image searches via pinterest are driving response via your site (sales/leads). Thanks! John

If you visit your Google Webmaster account, you can instruct Google not to display your links like that on your search result page. The content="noodp,noydir" syntax is to prevent other Directories from displaying (or cache) different meta descriptions about your site.
