Hi,
In a product description, we have links such as:
<a href="http://oursite.com/hire-ladies-costumes/dazzling-silver-disco"> (Used in an image link)

Now that we are using SSL, I'm fixing those products to not give the 'Not secure' message in browsers.

My question is:
Is changing it to <a href="/hire-ladies-costumes/dazzling-silver-disco">
a good fix? It works.

OR for ranking etc. should it include our domain name: https://oursite.com/hire-ladies-costumes/dazzling-silver-disco">

Both work, but I don't know if one provides better link optimisation or is considered an internal link etc?

I have about 4000 to change, so this is quite important to get right :)

Thanks!
