Another disadvantage is that even an individual or small group of people can harm image of an established brand. For instance Dopplegnager is a term that is used to disapprove an image about a certain brand that is spread by anti-brand activists, bloggers, and opinion leaders. The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016).
In addition to helping you find keywords you should be bidding on, thorough keyword research can also help you identify negative keywords – search terms that you should exclude from your campaigns. Negative keywords aren’t terms with negative connotations, but rather irrelevant terms that are highly unlikely to result in conversions. For example, if you sell ice cream, you might want to exclude the keyword “ice cream recipes”, as users searching for ice cream recipes are unlikely to be in the market for your product.
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.
To do that, you need a consolidated view of customer preferences and expectations across all channels – web, social media, mobile, direct mail, point of sale, etc. Retailers do this using omnichannel retail analytics. Marketers can use this information to create and anticipate consistent, coordinated customer experiences that will move customers along in the buying cycle. The deeper your customer insight into behavior and preferences, the more likely you are to engage them in lucrative interactions.
