Ever heard of Maslow's hierarchy of needs? It's a theory of psychology that prioritizes the most fundamental human needs (like air, water, and physical safety) over more advanced needs (like esteem and social belonging). The theory is that you can't achieve the needs at the top without ensuring the more fundamental needs are met first. Love doesn't matter if you don't have food.
Companies that employ overly aggressive techniques can get their client websites banned from the search results. In 2005, the Wall Street Journal reported on a company, Traffic Power, which allegedly used high-risk techniques and failed to disclose those risks to its clients. Wired magazine reported that the same company sued blogger and SEO Aaron Wall for writing about the ban. Google's Matt Cutts later confirmed that Google did in fact ban Traffic Power and some of its clients.
We now have a dedicated SEO strategist who, among other things, develops 90 day plans for our websites. 90 days isn't longterm planning, but at least we have a strategic objective for the quarter. He also works closely with our UX team to identify the target audience - the crew that does the persona research and focus groups prior to the wireframe stage.
Although this is a step-by-step series, everyone's methods will (and should) vary, so it really depends on how much time you think it will take (if you're billing hourly). What tools do you have at your disposal vs. how much researching for information will you have to do on your own? Will you have to pay for research reports or companies? Do you pay a monthly service for data or research?
Search engines may penalize sites they discover using black or grey hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices. Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's search engine results page.
Sending out regular newsletters and promoting offers through email is a great way to stay in touch with your customers and can also help to get traffic to your website. Provide useful information and links to pages on your website where they can learn more, such as through blog posts and landing pages for particular offers.
