Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.
As the speed of change in the marketing environment quickens, time horizons are becoming shorter. Nevertheless, most firms carry out strategic planning every 3– 5 years and treat the process as a means of checking whether the company is on track to achieve its vision and mission. Ideally, strategies are both dynamic and interactive, partially planned and partially unplanned. Strategies are broad in their scope in order to enable a firm to react to unforeseen developments while trying to keep focused on a specific pathway. A key aspect of marketing strategy is to keep marketing consistent with a company's overarching mission statement.
Strategic analysis is designed to address the first strategic question, "Where are we now?"  Traditional market research is less useful for strategic marketing because the analyst is not seeking insights about customer attitudes and preferences. Instead strategic analysts are seeking insights about the firm's operating environment with a view to identifying possible future scenarios, opportunities and threats.
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.
A fourth question may be added to the list, namely 'How do we know when we got there?' Due to increasing need for accountability, many marketing organisations use a variety of marketing metrics to track strategic performance, allowing for corrective action to be taken as required. On the surface, strategic planning seeks to address three simple questions, however, the research and analysis involved in strategic planning is very sophisticated and requires a great deal of skill and judgement.
Marketing strategies should ideally have longer lifespans than individual marketing plans because they contain value propositions and other key elements of a company’s brand, which generally hold consistent over the long haul. In other words, marketing strategies cover big-picture messaging, while marketing plans delineate the logistical details of specific campaigns.
