Lou Carbone, UX Guru – Experience Management

- effect vs. function: manage how users feel as opposed to what you are doing for them (fedex, airlines, rotorooter, etc.)

- think about the details! users remember how they felt more than they remember what they did

Nathan Buggia, MSFT, Live Search – SEO

- 30% of all traffic to web sites is from search engines

- html tips

o <title> and <h1> tags are the 2 most heavily weighted; <h1> is actually SUPER important on since it’s used to parse organization of content

o semantic html is impt (i.e. <h1>title</h1> more easily read by robots <span class=’header’>title</span>);

o make text in href tags meaningful (i.e. not ‘click here’)

o <meta>: keywords is unused, description is used for snippet

o fqdn is important (i.e. is higher than since rank is aggregated at fqdn, not at folder level (although google does consider folders)

o use RIA for spice within html pages, or at the very least have distinct urls for desired search rankings

- google is only search engine of the big 3 (google/yahoo/live) that will follow javascript redirects; need to use 301 redirect if you care

- yahoo site explorer ( : see inbound links to your page

- prefer hyphen to underscores, since search engines are likely to interpret “_” as part of word, not as word delineators

- casing matters (since 50% of since run apache). links and links distributed to other sites need to always use the same case.

- link to the root, not to a specific page (i.e. not

- http codes

o 304 – conditional get (useful for letting engines know your page hasn’t changed to save you bandwidth)

o 503 – down for maintenance

o 302 – temporary redirect (BAD! since “temporary” is ambiguous; always use 301)
