Nofollow
A backlink that carries the “nofollow” HTML tag. This indicates to search engines that should not count as a vote of quality for that site.
Some sites, particularly those with user-generated content, will mark all of their backlinks as nofollow, to avoid abuse of their content systems to generate backlink SEO value for third-party websites.

Return on Investment (ROI)
A calculation of the cost for an ad or marketing campaign, compared to the amount of trackable revenue it provided for the company. ROI is an important metric for many campaigns, because it relates directly to the profitability of an ad or project.
Sometimes revenue can’t be tracked precisely and attributed to an ad or campaign, though many digital ads are now able to provide this granular tracking to aid in business decisions.
