I would also advise to continue doing what works. If something you have rolled out generates great traffic and links bring out a new version of the content, for example the 2012 version worked effectively bring out the 2013 version of the content. Another effective strategy is to make the piece of content into an evergreen article which you add to over time so it is always up to date.
There is absolutely no reason why your on-page optimization should not be perfect. It can mean the different between your website showing up on page three of the search results and your website being the top listing. We encounter so many local businesses that simply ignore their on-page optimization (or the prior SEO company didn’t optimize correctly).
It is important to target keywords that your target consumer is likely to search for while looking for the product or service that you offer. For example, if you are an accounting firm located in Miami you would not want to target a general keyword such as “accounting firm.” Not only is it a very difficult keyword, but also you will be attracting visitors from all over the globe. Instead, you would want to target a more precise keyword such as “accounting firm in Miami” or “Miami accounting firm.”
Clients often ask me the difference and I give them a simple answer that normally puts an end to the conversation and their questions, much like the answer shane thomas gave, but less detailed. Direct is people putting in your url in the top and organic is people searching for you. Here is an example: If I want to buy a book i type in amazon.com (direct traffic) but if i forgot where to buy a book online i search for "where to buy a book online" which directs me to amazon.com (organic traffic). When i explain it like this, a light bulb goes off and they understand. Hope that helps.
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
