Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[42] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[42]

"As an owner of a small search engine marketing company, having access to the latest info on SEO is critical. I have had consultation phone calls with many of the top SEO'S and have sent my employees to training at one of the very top search marketing companies. Talking to Jim has been the best experience yet. He doesn't beat around the bush and tells you the real deal on getting organic ranks. We were stumped in particular on link building despite doing it for many years. Even after researching through forums and asking questions at the search strategies conference, we still did not have the whole picture and a practical set of white hat techniques to employ. Jim solved that among other technical issues our programmer had. I am truly looking forward to our next chat." John M.

Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time.[50] Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched.[51] Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability".[50] Due to selective attention from viewers, there is the likelihood that the message may not be received.[52] The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision.[53] These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time,[50] therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition.[50] This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand.[50] These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached.[54] Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control".[50] As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
Ao contrário do que muitos afiliados acham, anúncios também precisam ser relevantes para o seu público-alvo. Existem imensos afiliados que promovem produtos através de anúncios de Facebook, Google AdWords e native ads, sem se preocuparem minimamente com a relevância do produto para o público-alvo. Muitos deles utilizam inclusive estratégias de copywriting com o objetivo de enganar esse público e levá-lo a clicar nos anúncios.

Na internet, esse modelo de comissão sobre as vendas é chamado de marketing de afiliados ou affiliate marketing (em inglês). O primeiro programa de afiliados na internet foi criado em 1996 pela Amazon e se chamava Amazon Associates. O programa continua existindo até hoje e foi um dos principais propulsores de crescimento da Amazon, uma vez que milhares de afiliados promoviam os produtos da empresa nos Estados Unidos, recebendo uma fatia sobre as vendas. Caso eles não gerassem vendas, a Amazon também não estaria investindo dinheiro nenhum com essa publicidade, uma vez que ela pagaria uma comissão somente por vendas realizadas.
