Let's say you recently changed your blog path from /articles/* to /blog/*. This will impact your SEO on search engines and the links where you had shared before if you don't have a redirect rule for this situation. You could get all the paths for your posts and set a rule for each of them, but that wouldn't be necessary. Instead, you could set a rule to apply to all.
Netlify
On Netlify, you could either use netlify.toml file or _redirects file set the redirect rule.
For netlify.toml, the rule should look like this:
[[redirects]]
from = "/articles/*"
to = "/blog/:splat"
status = 301
And here is how it looks in _redirects:
/articles/* /blog/:splat 301
Vercel
For Vercel, we're gonna use vercel.json:
{
"redirects": [
{ "source": "/articles/(.*)", "destination": "/blog/$1", "statusCode": 301 }
]
}
