Second thing, optimizing across additional platforms. So we've looked and YouTube and Google Images account for about half of the overall volume that goes to Google web search. So between these two platforms, you've got a significant amount of additional traffic that you can optimize for. Images has actually gotten less aggressive. Right now they've taken away the "view image directly" link so that more people are visiting websites via Google Images. YouTube, obviously, this is a great place to build brand affinity, to build awareness, to create demand, this kind of demand generation to get your content in front of people. So these two are great platforms for that.
Plan your link structure. Start with the main navigation and decide how to best connect pages both physically (URL structure) and virtually (internal links) to clearly establish your content themes. Try to include at least 3-5 quality subpages under each core silo landing page. Link internally between the subpages. Link each subpage back up to the main silo landing page.
For a small business, it is better to start with Organic SEO because aside from it is a low-cost investment, it will build your internet presence gradually and eventually have a solid foundation in your own niche – provided that you are doing the right way. It is not bad to invest in non-organic. You just have to make sure that you are investing on the right campaigns and not on the overly artificial ways to gain traffic and rank. Avoid investing too much on paid advertising and instead invest on creating relevant and useful content.

Before you dig into some of the more technical ways to improve SEO ranking, always remember that writing compelling, high-quality content that attracts interest and compels visitors to share it and link back to it is vital. Good content has the best chance of being viral content, and Google rewards content virality heavily in its rankings algorithm.

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.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
