If you must include the Techcrunch icon (even when the product hasn't been featured in Techcrunch?) it might be best to direct the clickthrough to a Google site-search rather than a general Bing keyword search.
So, for example, the Techcrunch icon under RocketClub could direct to: https://www.google.co.uk/#q=site:techcrunch.com+RocketClub
However, given the fact that only a very small number of products featured on Product Hunt will be covered by Techcrunch, but may be covered by other publications/blogs, it might be better to link directly to a Google News search?
For example: https://www.google.co.uk/#q=RocketClub&tbm=nws
