Because users have different operating systems, web browsers[84] and computer hardware (including mobile devices and different screen sizes), online ads may appear to users differently from how the advertiser intended, or the ads may not display properly at all. A 2012 comScore study revealed that, on average, 31% of ads were not "in-view" when rendered, meaning they never had an opportunity to be seen.[85] Rich media ads create even greater compatibility problems, as some developers may use competing (and exclusive) software to render the ads (see e.g. Comparison of HTML 5 and Flash).
Mobile advertising is ad copy delivered through wireless mobile devices such as smartphones, feature phones, or tablet computers. Mobile advertising may take the form of static or rich media display ads, SMS (Short Message Service) or MMS (Multimedia Messaging Service) ads, mobile search ads, advertising within mobile websites, or ads within mobile applications or games (such as interstitial ads, "advergaming," or application sponsorship).[24]:23 Industry groups such as the Mobile Marketing Association have attempted to standardize mobile ad unit specifications, similar to the IAB's efforts for general online advertising.[49]
Collaborative Environment: A collaborative environment can be set up between the organization, the technology service provider, and the digital agencies to optimize effort, resource sharing, reusability and communications.[36] Additionally, organizations are inviting their customers to help them better understand how to service them. This source of data is called User Generated Content. Much of this is acquired via company websites where the organization invites people to share ideas that are then evaluated by other users of the site. The most popular ideas are evaluated and implemented in some form. Using this method of acquiring data and developing new products can foster the organizations relationship with their customer as well as spawn ideas that would otherwise be overlooked. UGC is low-cost advertising as it is directly from the consumers and can save advertising costs for the organisation.
I know a few of you just thought, “I cannot run my business like that”. So work with this. Instead of sending endless sale item emails, send just one “give” email a month. And what if you sent a really cool story of what someone has done with your products once a month? If you send weekly emails, just adding those two emails into the mix every month now means you’re on 1 to 1 schedule. Will your sales go down if you do this? Maybe a little. Will your engagement go up over time if you execute this well? Like a rocket ship.
Online advertisers can collect data on their ads' effectiveness, such as the size of the potential audience or actual audience response,[19]:119 how a visitor reached their advertisement, whether the advertisement resulted in a sale, and whether an ad actually loaded within a visitor's view.[59][60]:59 This helps online advertisers improve their ad campaigns over time.
Consider sharing the focus of the email between the call to action you want from your user and offering them something like a discount, early access to a new product, or a free trial period for subscription-based services. Get creative here. Give serious thought to what your customers will find valuable. No one knows their needs better than you and don’t be scared to do some research into what they’d want.
Next up is building an email newsletter. The best services offer several ways to do this; you can import your own HTML, start from scratch, or use a pre-designed template. Most of these services have drag-and-drop UIs that let you choose exactly the elements you want to include, as well as image libraries in which you can store assets such as your logo or company photos. Tools that let you test your emails for spam are also essential since there are some seemingly innocuous terms that may send up red flags and drop all of your hard work into your subscribers' junk folders or, worse, get your emails banned before they ever reach their recipients.
Online marketing is the practice of leveraging web-based channels to spread a message about a company’s brand, products, or services to its potential customers. The methods and techniques used for online marketing include email, social media, display advertising, search engine optimization, and more. The objective of marketing is to reach potential customers through the channels where they spend time reading, searching, shopping, or socializing online.
Advertisers have a wide variety of ways of presenting their promotional messages, including the ability to convey images, video, audio, and links. Unlike many offline ads, online ads also can be interactive.[18] For example, some ads let users input queries[69] or let users follow the advertiser on social media.[70] Online ads can even incorporate games.[71]
I typically create my email artwork in photoshop and then just drop in the jpeg using html and image mapping. Is there a “best practices” when it comes to actually putting the email together? Perhaps speaking from an editing perspective? Basically I make one big image and then use coding: img name, src, alt, a href and so forth. And for every different block, I simply create a new jpg image to use. Is there a better way I should be doing this?
Understanding Mobiles: Understanding mobile devices is a significant aspect of digital marketing because smartphones and tablets are now responsible for 64% of the time US consumers are online (Whiteside, 2016).[42] Apps provide a big opportunity as well as challenge for the marketers because firstly the app needs to be downloaded and secondly the person needs to actually use it. This may be difficult as ‘half the time spent on smartphone apps occurs on the individuals single most used app, and almost 85% of their time on the top four rated apps’ (Whiteside, 2016).[42] Mobile advertising can assist in achieving a variety of commercial objectives and it is effective due to taking over the entire screen, and voice or status is likely to be considered highly; although the message must not be seen or thought of as intrusive (Whiteside, 2016).[42] Disadvantages of digital media used on mobile devices also include limited creative capabilities, and reach. Although there are many positive aspects including the users entitlement to select product information, digital media creating a flexible message platform and there is potential for direct selling (Belch & Belch, 2012).[44]

Furthermore, advertisers may encounter legal problems if legally required information doesn't actually display to users, even if that failure is due to technological heterogeneity.[86]:i In the United States, the FTC has released a set of guidelines indicating that it's the advertisers' responsibility to ensure the ads display any required disclosures or disclaimers, irrespective of the users' technology.[86]:4–8

Game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[50] 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"[50] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.

The books I've written have actually had three different titles, updated to move with the times. My first text book was titled: Internet Marketing: Strategy, Implementation and Practice. I then created E-business E-commerce Management and, with PR Smith, E-marketing Excellence, for professionals a couple of years later. Then, much later, the names switched and in 2012 we renamed the Internet Marketing book to Digital Marketing with the others becoming Digital Business and Digital Marketing Excellence.  About time too, since I was involved in developing the syllabus as an examiner for the first IDM Diploma in Digital Marketing back in 2004-5 when the term was hardly used at all - so it's been great to see 'Digital Marketing' adopted as the 'de facto' term, when I was first involved in defining it with the IDM students in 2004!

Use personalization. Personalizing the content of your emails (depending on your segment from Chapter 3) will make it infinitely more relevant and valuable to them. Personalization is so much more than inserting your subscriber’s first name into the email. You need to tailor the actual content of the email to address their needs. For instance, an online retailer will find it much more valuable to read an email with the subject line, “How to build backlinks to your eCommerce store” than just a generic subject line, “How to build backlinks.”
An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
