The guest speaker spode about search engine optimization and these are some points I thought were interesting:

1. Keywords play a major factor in search engine optimization, but not just having the right keywords. It is also important to have the right location of keywords, such as title tags, headings, body text, meta tags, and picture text.

2. I also thought is was very interesting that how popular your site is can influence your search engine rank, which Google calls Page Rank. The popularity of your site can be measured by how many other sites have links to your pages.

3. I also thought he brought up a good point of calculating what a "click" is with to you before you initiate PPC strategies. It is an obvious step to take, but I can see a lot of companies not making proper predictions and setting themselves up for failure. Maybe that had some contribution to the dotcom crash of some compaines?
