About three months ago, I shared some holiday SEO tips on Search Engine Land — and since SEO is not a quick-fix, immediate return kind of thing, August is when you need to be thinking about holiday SEO tactics.

On the PPC side, you don’t need such an early start. A great PPC campaign can bring immediate results. So, with that in mind, small businesses who are looking for some holiday PPC hints may want to check out this webinar Yahoo is hosting on Wednesday:

Holiday Trends and Best Practices for Sponsored Search

Yahoo tells me the webinar is “specifically for small businesses, to share shopping trend information and search marketing best practices based on data from Yahoo!’s extensive user and advertiser base.”

It starts at 10:00 am Pacific on Wednesday. It’s free.
