There are several ways to approach optimizing and promoting your SEO website. Professional search engine optimization includes quality and low keyword density content with a side of organic promotion. Both what is offered on your website along with how it is promoted outside of your actual domain need to work for you as opposed to against you.
An SEO marketer can pick the most lucrative niche available and still fail, and many have done just that. Websites with poorly optimized on-site and off-site promotional content always end up with little to no profit. Professional search engine optimization includes working with high traffic niches, creating optimized and quality content, and properly promoting said content on other websites to generate links and general interest.
A combination of quality content all-around is what gets many new SEO marketers. Many will settle for low-quality on-site website content, through the roof keyword densities, poor off-site web content, or inappropriate back links. Ensuring that the overall campaign focuses on exact keywords within a niche and does not veer off of the track will get people looking for information on a specific subject to notice you, pay more attention to your content, and stay on the site longer. They will also be more likely to click the advertisements within your website, which is your ultimate goal.
Creating a campaign focusing around specific keywords is also a big part to how Google notices your content. Keeping individual pages to one keyword phrase at a time will ensure that you will get traffic from specific searches for each page. For example, say an SEO marketer has a website dedicated to the bedroom furniture niche. Having different pages within the site focus on different types of bedroom furniture, and one specifically tailored to the keyword "bedroom furniture" is going to be far more effective than a website that has a page with every niche keyword in one content body.
When promoting your content via other websites, be sure that the content that links back to your site also has to do with your niche. Keeping the entire campaign within the niche will avoid reader and Google confusion, both of which can lead to the downfall of any website. Professional search engine optimization techniques incorporate the niche into every facet of the campaign with a combination of moderate keyword usage and quality content on and off the main website.
