At this point, you have done your keyword research and an initial placement report.
The next steps have to do with on-page and off-page optimization. Let’s look at both optimization tactics individually.
On-page optimization is the process of optimizing each page of your website for the keywords that you have determined are important to your business. On-page optimization can be divided into a few categories: copy, meta-content and site structure. Each category is critically important.
Keyword placement, density and frequency are all factors in writing copy.
Writing meta-titles, meta-content and keywords with the correct length and keyword density are musts for good SEO placement.
Make sure that your URLs are search friendly. For example, rather than www.yourdomain.com/?^&$34987467.html use www.yourdomain.com/product_name.html
Off-page optimization really comes down to link popularity (quality and quantity of websites linking to your website). There are many business directories that will include a link to your site when you submit to the directory. Also, directoried like ODP are considered high value links back to your site. Here’s a good blog posting on link popularity.
SEO is a time consuming, yet worthwhile effort if your homework is done and you have identified an online opportunity for your company.
