Barney stated that for resources to hold potential as sources of sustainable competitive advantage, they should be valuable, rare and imperfectly imitable.[75] A key insight arising from the resource-based view is that not all resources are of equal importance nor possess the potential to become a source of sustainable competitive advantage.[73] The sustainability of any competitive advantage depends on the extent to which resources can be imitated or substituted.[6] Barney and others point out that understanding the causal relationship between the sources of advantage and successful strategies can be very difficult in practice.[75] Barney uses the term "causally ambiguous" which he describes as a situation when "the link between the resources controlled by the firm and the firm's sustained competitive advantage is not understood or understood only very imperfectly." Thus, a great deal of managerial effort must be invested in identifying, understanding and classifying core competencies. In addition, management must invest in organisational learning to develop and maintain key resources and competencies.
Market pioneers are known to often open a new market to consumers based off a major innovation.[93] They emphasise these product developments, and in a significant number of cases, studies have shown that early entrants – or pioneers – into a market have serious market-share advantages above all those who enter later.[94] Pioneers have the first-mover advantage, and in order to have this advantage, business’ must ensure they have at least one or more of three primary sources: Technological Leadership, Preemption of Assets or Buyer Switching Costs.[92] Technological Leadership means gaining an advantage through either Research and Development or the “learning curve”.[92] This lets a business use the research and development stage as a key point of selling due to primary research of a new or developed product. Preemption of Assets can help gain an advantage through acquiring scarce assets within a certain market, allowing the first-mover to be able to have control of existing assets rather than those that are created through new technology.[92] Thus allowing pre-existing information to be used and a lower risk when first entering a new market. By being a first entrant, it is easy to avoid higher switching costs compared to later entrants. For example, those who enter later would have to invest more expenditure in order to encourage customers away from early entrants.[92] However, while Market Pioneers may have the “highest probability of engaging in product development”[95] and lower switching costs, to have the first-mover advantage, it can be more expensive due to product innovation being more costly than product imitation. It has been found that while Pioneers in both consumer goods and industrial markets have gained “significant sales advantages”,[96] they incur larger disadvantages cost-wise.
Meta keywords are different from usual keywords since they are only in the source code of your web page, instead of the living, visible web page. Anyway, meta keywords can be filled out later on if you need to, but focus on the things that matter first. Integrate keywords for the meta description tag. Do this just for the page description that comes up in search engines.

Cost per click was more common in the early days of affiliate marketing but has diminished in use over time due to click fraud issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to the diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.
