I've tried searching and read the Questions that may already have your answer list, but couldn't find an answer.
This is about a category page that lists products in it, you click one and go to the actual product page (not sure if there's a common term for that kind of pages). I worked with a person some time ago who claimed that it's better to, where possible, wrap the thumbnails and item names with one common parent anchor
Here's an example:
<a href="/product1"> <img src="/product1.jpg" alt="Product One"> <h4>Product One</h4> </a>
vs. the traditional
<a href="/product1"> <img src="/product1.jpg" alt="Product One"> </a> <h4> <a href="/product1">Product One</a> </h4>
Let's say we can style them both equally and there's no difference from that perspective, what would be better for SEO?
