Then you visit each and every site and compare it to the criteria that you have created for your award. In fact, you should only compare it against the criteria that you had posted at the time the site was submitted . So let's check a site against the criteria. You surf to it and find that it seems to download very slowly. If the page has 500kb of graphics, then the site flunks immediately - go on to the next one.
Readable text is next on the list.
If so, the site passes - if not, it doesn't. The web is a dynamic place and static, unchanging sites quickly die. Or do you mean only internal links - still, check them all could be a huge undertaking. If the site has too many flunks, it does not get the award. It you subscribe to the theory of ethical awards programs, you grant the award - and then you update your criteria.
