If you are using a blog to promote a business, enable comments. Many businesses leave their comments turned off to avoid spam. If you allow site visitors to leave comments on your articles within your blog, though, it provides new content for your blog that is unique and free. Since search engines love content that is unique, the comment section can help your search engine rankings increase on your blog.
When creating the URL for your website, use a keyword phrase. Search engines will place more value on your URL when searches are done for those keywords. By using a keyword phrase that is popular, your URL will show up more frequently in the search engines.
