Excessive search engine submittal, broken links, excessive punctuation, empty alt attributes, spam (this refers to any attempt to trick a search engine, such as using irrelevant keywords to draw extra hits, placing invisible content on the page to boost keyword density, and using meta refreshes -often in combination with irrelevant keywords- to draw a user in for an irrelevant search and then direct them to the page you want them to see. These techniques can result in a ban from search engines if they catch them.)
