You shouldn’t force the reader to use the “search” functionality to find a blog post you refer to, just link to it in your post. Make it easy for them to find the rest of your interesting work. This also allows search engines to understand your content better. And if you read an interesting post on someone else’ site, link to it, refer to it in your post.
TIP: Link to previous posts on your blog, and to others
This is part of the first series of posts about how to write for your blog.
