Make sure your backlinks appear to be natural. Don’t ask webmasters to link back to your pages with a specific anchor text since this can haphazardly result in a pattern that may get noticed by search engines and cause you to get a linking penalty, a la Penguin. Also, don’t do anything shady or unnatural to create backlinks, like asking a site to put a link in the footer of every page on their site.
For many businesses, getting the technical aspects of SEO right, understanding the keywords you want to target, and having a strategy for getting your site’s pages linked to and shared is really all you need to know about SEO. There are, however, some specific cases and business types that need to be concerned with specific types of search. A few types of search environments that require unique approaches include:
Word of mouth communications and peer-to-peer dialogue often have a greater effect on customers, since they are not sent directly from the company and are therefore not planned. Customers are more likely to trust other customers’ experiences. Examples can be that social media users share food products and meal experiences highlighting certain brands and franchises. This was noted in a study on Instagram, where researchers observed that adolescent Instagram users' posted images of food-related experiences within their social networks, providing free advertising for the products.
Also, backlinks are important for the end user. With an end user, backlinks connect searchers with information that is similar to what is being written on other resources. An example of this happens when an end user is reading a page that discusses “how child care expenses are driving women out of the workforce.” As they scroll down, they might see another link with a study on “how the rise in child care costs over the last 25 years affected women’s employment.” In this case, a backlink establishes connection points for information that a searcher may be interested in clicking. This external link creates a solid experience because it transfers the user directly to additionally desirable information if needed.
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.
