The half time of an external link is two years, hence Link rot is a continuous process.
Maintenance Frequency at a Glance gives you the relation between the maintenance frequency of your website and the percentage of broken links at your site. This might help you to decide how often you should check your website for broken links.
Enter the maximum percentage of external broken links that is acceptable for you and I tell you how often you should check for broken links.
When 3% broken links is acceptable, you should check your site every 1 month.
Enter how often you check for broken links and I tell you what percentage broken links you might expect.
Everyone, including the engineers of search engines like Google and Bing, do not expect that you check your site for broken links at a daily base. At the other hand nobody likes a website with a lot of broken links. So how often should you check your website for broken links?
The answer is "That depends". It depends on the number of external links you have, the time you have for checking broken links and the percentage broken links at similar competitive sites.
In general my advice is to check for broken links every 1 to 3 months with Broken Links at a Glance or Xenu's Link Sleuth.
Hope that helps,
Hans
