They determine “quality” by a number of means, but prominent among those is still the number and quality of other websites that link to your page and your site as a whole. To put it extremely simply: If the only sites that link to your blue widget site are blogs that no one else on the Web has linked to, and my blue widget site gets links from trusted places that are linked to frequently, like CNN.com, my site will be more trusted (and assumed to be higher quality) than yours.
One thing that has worked well for me lately that can work well (and may help with the infographic promotion) is surveys. Google Forms allow you to create a survey for free. Think of interesting questions to your niche and start promoting the survey (ask well known influencers in your niche to share the survey with their social followers to help with responses. Offer them a link as a contributor once the survey is complete). Once you have a few hundred responses, you can create a commentary about your findings (Google also puts the data into graphs). If you have enough responses and the information is interesting, get in touch with the same bloggers who helped push it out there to see if they would be happy to share the results. The beauty of this method is that if the results are interesting enough, you might end up getting a link back from a huge news site.
In 2013, the Tenth Circuit Court of Appeals held in Lens.com, Inc. v. 1-800 Contacts, Inc. that online contact lens seller Lens.com did not commit trademark infringement when it purchased search advertisements using competitor 1-800 Contacts' federally registered 1800 CONTACTS trademark as a keyword. In August 2016, the Federal Trade Commission filed an administrative complaint against 1-800 Contacts alleging, among other things, that its trademark enforcement practices in the search engine marketing space have unreasonably restrained competition in violation of the FTC Act. 1-800 Contacts has denied all wrongdoing and is scheduled to appear before an FTC administrative law judge in April 2017.
