Does redirecting many old pages to the homepage help or trigger a soft-404?

It can trigger soft-404 treatment, which defeats the reason for doing it. Google’s site move guidance says: “Don’t redirect many old URLs to one irrelevant single URL destination, such as the home page of the new site. This can confuse users and might be treated as a soft 404 error.” A homepage does not answer what a product page, a guide, or an event page promised, so a mass redirect to it sends visitors to the wrong place and gives Google little reason to treat the redirects as real replacements.
What a soft 404 means here
A soft 404 is a URL that looks like it works but behaves like a missing page. Search Console’s Page indexing help lists soft 404 as its own status and recommends a real 404 response code for pages that are truly not found. When Google treats a redirect as a soft 404, the old URL is handled as gone, so the cleanup you hoped would preserve value ends up behaving like a set of deletions that also confuse users.
Map each old URL to its closest match
Redirects work when each old URL lands on the page that best replaces it. For a large batch, build a mapping sheet with three columns: old URL, closest current page, and reason. Then sort the old URLs into groups:
| Old URL | Destination |
|---|---|
| A post that has a newer version | The newer post |
| A post with no newer version but a close topic match | The current post on that topic, if it answers the same question |
| A product with a direct successor | The successor |
| A product in a range that still exists | The current category for that range, only when shoppers would find the replacement there |
| Anything with no reasonable match | A 404 |
Sending every old blog post to the blog index repeats the homepage problem on a smaller scale: the index lists posts, it does not answer the question the old post answered. Use a section page only when it serves the same need as the old URL. Where no match exists, a clean 404 is the accurate response; the reasoning is in whether to redirect a deleted page or let it 404.
How to tell whether it went wrong
Watch the Page indexing report after the redirects go live. Old URLs that show up as soft 404s, rather than as pages with a redirect, are the ones Google did not accept as replacements. Check a sample by hand: open the old URL, land on the target, and ask whether a visitor would recognize it as what they were looking for. Any URL that fails that check should get a better target or a 404, not a second look at the homepage.
