It is common to overlook the social sharing counts on your pages when you’re moving from one domain to another or migrating to HTTPS, particularly on blog posts. Those little numbers beside the icons may seem trivial, but social proof remains a key indicator of reputability and quality.
Unfortunately, these buttons are hopelessly attached to the current page address in a near-literal way — they do not follow redirected URLs. And that means that after a migration the buttons will likely show no shares at all.
So how do you prevent this from happening? It’s easy-ish. You just have to tell the buttons where the original page was located so that the original share counts are brought forward.
You could do this manually, but many platforms — HubSpot and various WordPress themes and plugins included — automatically insert social buttons on posts and pages, leaving no opportunity to manually edit where they point to. And, anyway, it’s totally better if you automate this sort of stuff.
