It's always nice to see Google publicly approve of good SEO.
Google has said before that search engine optimization, or SEO, can be positive and constructive—and we're not the only ones. Effective search engine optimization can make a site more crawlable and make individual pages more accessible and easier to find. Search engine optimization includes things as simple as keyword research to ensure that the right words are on the page, not just industry jargon that normal people will never type.
“White hat” search engine optimizers often improve the usability of a site, help create great content, or make sites faster, which is good for both users and search engines. Good search engine optimization can also mean good marketing: thinking about creative ways to make a site more compelling, which can help with search engines as well as social media. The net result of making a great site is often greater awareness of that site on the web, which can translate into more people linking to or visiting a site.
But it's always scary to know that something is about to come down the google pipeline that might cause a big rankings upset, aka Panda-style.
In the next few days, we’re launching an important algorithm change targeted at webspam. The change will decrease rankings for sites that we believe are violating Google’s existing quality guidelines.
Good luck, y'all.
