Sorry to post so much today, but I wanted to share this Squidoo tip before I forgot. Old hands know this already: where relevant, use the year in your page title (but NOT in your URL, since you’ll want to change the title each year.)
Users who search for product reviews, news or information often include the date (“best flatscreen TVs 2011″). People sometimes do this to filter results which are eclipsed by another similar but different search (“2004 eruption Mt Saint Helens” as opposed to the 1980 eruption). For certain topics, people may even include the day and month.
I noticed my new Volcanic Eruptions Update lens is getting a lot of date-based hits, so I added the month/year to the end of the title. The catch, of course, is that this only works for pages which you update substantially and often enough to justify the monthly (or at least yearly) title change.
