4-year old 404 errors

[NVentouris]

Hi all

Just bought a well known tool for link research and I found that I have about 27.000 broken backlinks. Most of them are about 3 to 5 years old and non indexed of course.
Is there any seo value to redirect them one by one ? (There is UX value of course)

Thank you all

Is it 27,000 individual links that go to (presumably) a much smaller amount of pages? If so, the workload is how many pages to redirect, not how many individual links.

You're unlikely to see much benefit in the short term, (certainly not like in the past) but in the longer term you're likely to get credit for at least some of those links.

Some link tools are very aggressive about findings links, so it may be that they are not all worthwhile. My tendency would be to process the list to ensure you're not wasting time on bad links, scrapers, etc.
