I want to know how to control the links on the webpage, where the link leads to external sites. Sometimes it can be that an external site just vanishes and you don't know that such an event occurred.
I am thinking about making an Excel sheet which holds all links and it's places from the website. Then I go manually monthly over all links and check if the website exists (which I find a pretty stupid idea :/ )
Does anyone of you have a good system on maintaining external links?
Use Xenu.
Xenu's Link Sleuth (TM) checks Web sites for broken links. Link verification is done on "normal" links, images, frames, plug-ins, backgrounds, local image maps, style sheets, scripts and java applets. It displays a continously updated list of URLs which you can sort by different criteria. A report can be produced at any time.
If you're on Mac, have a look at Integrity.
