As you can tell I have been on a Google Webmaster Central kick lately. The Google Webmaster Central blog has collected some of their best and most informational posts and created the 7 must-read Webmaster Central blog posts. Seeing this collection has reminded me of some of the search engine optimization and search engine marketing hot issues, some of my favorites being...
Flash Best Practices
While many were glad to see Google address this, flash has been something that many SEO's stay away from like the plague. While there are several acceptable methods for optimizing a flash website none are particularly easy and sometimes results are hard to glean. There were always questions as to whether the search engines would accept these optimization techniques or whether they would learn to read flash, both seem to have been addressed over time.
The Supplemental Index
I remember several tools which could be used to see how many pages a website had in the Google supplemental index and I remember even more posts and discussions as to the use of the supplemental index and getting web pages out of it. I think many released a sigh of relief when Google disbanded its use so that website owners had one less thing to worry about.
The mention of duplicate content and penalties associated with it used to be a huge issue for many, especially those with larges websites which may have several overlapping pages. I was more than relieved when I learned that no penalties were actually associated with duplicate content but simply Google selecting which page to show for related searches. After many have spread the word about duplicate content this is still an issue that comes up and needs clarification. Many SEO's are still addressing duplicated content in that removing it or fixing the problem is great but getting Google to select the right version to show in searches may be more important.
