Online reviews have become one of the most important components in purchasing decisions by consumers in North America. According to a survey conducted by Dimensional Research which included over 1000 participants, 90% of respondents said that positive online reviews influenced their buying decisions and 94% will use a business with at least four stars.

Forrester Research predicts that by 2020, 42% of in-store sales will be from customers who are influenced by web product research.
Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
Social media itself is a catch-all term for sites that may provide radically different social actions. For instance, Twitter is a social site designed to let people share short messages or “updates” with others. Facebook, in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities.

Since social media marketing first came to be, strategists and markets have been getting smarter and more careful with the way they go about collecting information and distributing advertisements. With the presence of data collecting companies, there is no longer a need to target specific audiences. This can be seen as a large ethical gray area. For many users, this is a breach of privacy, but there are no laws that prevent these companies from using the information provided on their websites. Companies like Equifax, Inc., TransUnion Corp, and LexisNexis Group thrive on collecting and sharing personal information of social media users.[107] In 2012, Facebook purchased information from 70 million households from a third party company called Datalogix. Facebook later revealed that they purchased the information in order to create a more efficient advertising service.[108]
