Another excellent guide is Google’s “Search Engine Optimization Starter Guide.” This is a free PDF download that covers basic tips that Google provides to its own employees on how to get listed. You’ll find it here. Also well worth checking out is Moz’s “Beginner’s Guide To SEO,” which you’ll find here, and the SEO Success Pyramid from Small Business Search Marketing.
In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit, and the amount of traffic to the site dropped by 70%. On March 16, 2007, the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.
In the enterprise space, one major trend we're seeing lately is data import across the big players. Much of SEO involves working with the data Google gives you and then filling in all of the gaps. Google Search Console (formerly, Webmaster Tools) only gives you a 90-day window of data, so enterprise vendors, such as Conductor and Screaming Frog, are continually adding and importing data sources from other crawling databases (like DeepCrawl's). They're combining that with Google Search Console data for more accurate, ongoing Search Engine Results Page (SERP) monitoring and position tracking on specific keywords. SEMrush and Searchmetrics (in its enterprise Suite packages) offer this level of enterprise SERP monitoring as well, which can give your business a higher-level view of how you're doing against competitors.
