When you are working on search engine optimization within the content of your website, paying attention to all the little things you can do that will help will be one thing that will be important; while most of your competition will be paying attention to the big things, adding these little things to your repertoire of SEO tricks will go a long way in setting your site apart - and bringing you extra traffic as a result.
One thing that you need to realize is your site will probably rank a lot more highly if search engines are "crawling" your site on a regular basis, and it is not very likely that search engines will crawl your site on a regular basis if you are never adding new content; if your site does not "have a reason" to add new content at least three times per week, consider adding a blog section to your site, and update this at least three days a week in order to increase your crawl frequency.
Sharing link juice with yourself is another thing that will help your site; typically, when you think of link juice, you will think of the links you are giving to other sites, and the links they are giving to you, but you can also spread link juice throughout your own site - linking to certain posts or sections throughout your site.
And finally, remember that writing off-site articles, and submitting these articles to article databases, is a big key to SEO success: one of the benefits of this is that you will create an opportunity to gain new traffic through people clicking on the links in these articles, and another benefit is that you will increase your search engine ranking through the backlinks these articles create.
Regardless of whether you are running a website in order to promote your business or as a means to maybe make some money through the website itself, make sure you are always keeping your eyes open for the "little things" your competitors are missing - and take advantage of these as a way to gain an edge in the long run.
