Thursday, October 9th, 2008

Moderator: Danny Sullivan, Editor-in-Chief, Search Engine Land

Speaker: Nathan Buggia, Live Search Webmaster Central, Lead Program Manager, Microsoft

  • AJAX/HIJAX – Down-level experience, don’t use javascript for links, use <noscript> tags
  • CSS – can improve performance better by separating formatting from content, has been abused by Spammers to hide links and keywords

Speaker: Sharad Verma, Senior Product Manager, Web Search, Yahoo!

  • 3 pillars of 2.0: experience (last.fm, youtube.com), participation (tagging, reviews, comments, wiki, blogs, yelp), community (Facebook, Twitter, etc.)
  • 2.0 Tech: RSS, CSS
  • External CSS is better than regular CSS – efficient crawling (makes pages light, reduces file size, etc.)
  • To do w/ CSS: don’t disallow CSS in robots.txt, don’t hide text using CSS (white on white, display:none, etc.)
  • Are you a web site or web application? Search engines have a difficult time crawling javascript, AJAX content (Can’t be linked to, can’t be bookmarked, can have poor link juice and hence poor rankings, can’t be read from screen readers and text-based browsers)
  • SEs can index flash
  • Problems w/ flash: Most flash rendered with javascript, no deep linking → less link juice, one URL for the entire flash movie → bad user experience
  • RSS  – More visibility of your content on the web (users, publishers), more links and traffic to your site → higher rankings
  • Best bets: alternative navigation and content in HTML, submit sitemaps, robots.txt (don’t exclude CSS, javascript)

Speaker: Tony Adam, SEO Manager, Yahoo!

  • Think about user experience
  • Content controlled by javascript is not search engine friendly

Q & A

  • Do SEs use h1 tags? (Live and Google: uses h1, Yahoo: doesn’t use h1)
  • Submit sitemaps
  • Use short, concise URLs
  • Keywords in URLS!!!!
