Black hat SEO involves techniques such as paying to post links to a website on link farms, stuffing the metadata with nonrelated keywords, and using text that is invisible to readers to attract search engines. These and many other black hat SEO tactics may boost traffic, but search engines frown on the use of such measures. Search engines may punish sites that employ these methods by reducing their page rank or delisting them from search results.
It is increasingly advantageous for companies to use social media platforms to connect with their customers and create these dialogues and discussions. The potential reach of social media is indicated by the fact that in 2015, each month the Facebook app had more than 126 million average unique users and YouTube had over 97 million average unique users.[29]
The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests. Businesses can now use social media to select the age range, location, gender and interests of whom they would like their targeted post to be seen by. Furthermore, based on a customer's recent search history they can be ‘followed’ on the internet so they see advertisements from similar brands, products and services,[40] This allows businesses to target the specific customers that they know and feel will most benefit from their product or service, something that had limited capabilities up until the digital era.
In-game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[51] The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in their advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow or entertainment. The attitude towards the advertising also takes into account not only the message shown but also the attitude towards the game. Dependent of how enjoyable the game is will determine how the brand is perceived, meaning if the game isn't very enjoyable the consumer may subconsciously have a negative attitude towards the brand/product being advertised. In terms of Integrated Marketing Communication "integration of advertising in digital games into the general advertising, communication, and marketing strategy of the firm"[51] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.
Since heading tags typically make text contained in them larger than normal text on the page, this is a visual cue to users that this text is important and could help them understand something about the type of content underneath the heading text. Multiple heading sizes used in order create a hierarchical structure for your content, making it easier for users to navigate through your document.
The kind of content you create depends on your audience's needs at different stages in the buyer's journey. You should start by creating buyer personas (use these free templates, or try makemypersona.com) to identify what your audience's goals and challenges are in relation to your business. On a basic level, your online content should aim to help them meet these goals, and overcome their challenges.
Google allows businesses to create a free business profile, sometimes referred to as Google My Business (formerly Google Places). Your business profile includes your business name, a brief description, contact information, and even photos. In addition to Google, you should make sure your business is listed on a number of other online directories as well. Some examples include search engines like Bing, directories like Yahoo and Yellow Pages, and platforms like Yelp. Establishing your business listing on all of these sites can be time consuming, but services like Vistaprint's Search Engine Listing Manager can automate the process for you. By entering your information once, we can get you listed on more than 100 directories and sites. And whenever you want to make a change, we will update all of your listings with one click.

Facebook Ads and other social media ad platforms, for example, are pay-per-click platforms that do not fall under the SEM category. Instead of showing your ads to people who are searching for similar content like search ads do, social media sites introduce your product to people who happen to be just browsing through their feeds. These are two very, very different types of online advertising.
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".
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.
