This post is about the “white hat ethical content marketing” technique that’s a shade lighter than the old “oh, did we accidentally 301 that to a valuable page?” switcheroo. Many sites do this already, and some agencies recommend it for their clients (and I have mixed feelings about this). Currently I wouldn’t say it’s risky, but you shouldn’t listen to me.
“Link Anchors” (not anchor text), are those things that let you jump around annoyingly like this. People often use them to divide longform articles into more manageable chapters. This makes sense. It’s believed that Google only values up to the hash symbol when assessing links to a page.
