Search engine spiders love sites with well-chosen, well-placed and well-used keywords and key phrases. And you should too, because choosing your keywords correctly will make the difference between traffic and no traffic.
Here's a brief overview of why keywords are so important.
If a website or blog is generally about some topic such as "dog care", or "home repair", then articles, posts, comments, and products found on the site will reflect that focus through the use of terms or phrases related to the general topic. These are known as "keywords"
This is the basic assumption made by the search engines when analyzing the focus of your site. It the SE finds lots of "dog care" terms, then your site will be considered relevant to "dog care"
A "dog care" blog, for instance, will contain many different but related terms such as "dog health", "pet care", "dog food", etc., not to mention products related to dog care.
A "home repair" site will contain different terms such as "home repair", "home renovation", "bathroom remodeling", "kitchen upgrade", etc., etc.
So give the search engines what they want. When creating content for your site, be sure to focus on the correct keywords or keyword phrases.
