The lower the percentage broken links you allow, the more frequent you should check and repair broken links.
With the tool Maintenance Frequency at a Glance you are able to find out how often you should check for broken links.
This tool is based on research regarding the half time of broken links in a copy of the former Yahoo! directory.
Some findings are:
- When 3% broken links is acceptable, you should check your site every 1 month.
- When you check your site every 3 months, you might expect 8% broken links.
- When you check your site every 6 months, you might expect 16% broken links.
- When you check your site every year, you might expect 29% broken links.
- When you check your site every 2 year, you might expect 50% broken links.
I think that you should check for broken links at least every 3 months although I often advice to check your site every month for broken links.
For relative small sites I advice Broken Links at a Glance. For larger sites I advice Xenu's Link Sleuth.
Happy broken link hunting,
Hans
