This is what I wanted to accomplish, too. No need for the blog post title to show up as a breadcrumb. It’s repetitive since it also appears as the actual title below the breadcrumb.
But here’s a suggestion for anyone who happens to find this discussion: Replace the blog post title with something more generic, such as ‘Blog post.’ For my situation the reason I chose to do this has to do with being consistent in how categories are handled.
I have categories and tags visible on the bottom of my blog posts. Click one of them and you’re taken to a categories or tags page with blog post excerpts. The breadcrumb looks like this:
Homepage / Archive for Case updates
Click on one of the excerpts and you’re taken to the permalink page for that blog post, which looks like this:
Homepage / Case updates / The case of Casper the Friendly Ghost
You’re no longer in the archives, but the shortened ‘Case updates’ breadcrumb will take you back there if you want. But if you remove the blog post title from the breadcrumb, you have two different formats for what reads as the same breadcrumb, although it’s not since you’re not in the archives. You can add pagination to full-content permalink pages, as I’ve done, but it still breaks consistency with the breadcrumb, since you now have two formats:
Homepage / Archive for Case updates … and
Homepage / Case updates
So, I think the best practice is to keep the blog post title in the breadcrumb or replace it with a generic description, such as ‘Blog post’ or ‘Current reading:’ or some variation.
