Search engine optimization (SEO) is the process of increasing the quality and volume of unpaid traffic to a website or web page from search engines. The goal is targeted traffic, not just a higher ranking on Google, Yahoo, or Bing. Effective SEO rests on a small set of principles, each of which is covered below.

What are the core elements of SEO?
SEO works when a website delivers real value. Search engines treat content quality as a baseline rule and penalize sites that offer nothing useful to visitors. A page that just rehashes existing material without adding substance will not gain traction. Following webmaster guidelines for SEO is the same move: the guidelines exist to reward sites that serve readers, and sites that follow them benefit in rankings and in repeat visits.
Relevant content over spam
Relevant content will always outrank irrelevant or spam-style pages. Writing what visitors actually want to read is the simplest way to satisfy that rule.
Link building as the backbone of SEO
Link building has been called the backbone of SEO because it is the most fundamental part of any campaign. The process creates inbound links from other relevant sites, which take the place of direct inbound links from Google, Yahoo, or Bing. Strong link building is what allows a site to climb those rankings and can decide whether an SEM campaign succeeds or fails.
How do you start improving SEO?
Begin with the basics:
- Optimize meta tags and keyword density to lift traffic and improve the odds of being indexed by Google and Yahoo.
- Build out content for the site so it generates high-quality traffic.
- Hire professional writers who can produce articles about the niche, written in an interesting and unique way for the target audience.
What mistakes should you avoid?
Many site owners assume that once a site is popular, SEO no longer matters. In practice, SEO is what gets a site in front of the right audience and cannot guarantee a top spot on Google or Yahoo results pages on its own. A handful of methods and techniques help a site rank higher, and a few common errors hold sites back.
Make pages search-engine friendly
Pages should be search-engine friendly. That means using keywords in the content so indexing happens faster, and making sure the text is properly punctuated with correct grammar. Studying the pages of similar websites surfaces the keyword areas that are hard to optimize; those areas should be tackled first, before moving on to the harder ones. For example, a site that wants to rank higher for "how to lose weight" can study weight-loss websites to see how articles on the topic are written, what factors they cover, and what tips they offer.
Keep the site updated
A common mistake is treating SEO as a one-time job left to professionals. There is a lot a site owner can do directly, and there are software programs built for the optimization process that help pages rank higher for the keywords in use. When the work is too much to handle in-house, hiring a professional SEO company is a practical way to get the best optimization possible.
What does a well-optimized site look like?
A well-optimized site has unique, informative, and interesting content. It is built to appeal to users rather than to repeat keywords. Targeted traffic is the result, and users are less likely to click the first ad they see. For higher organic rankings, content should be added on a steady cadence, but never excessively. Advertising the site to traffic should also be avoided, since that approach leads to weaker organic search engine results pages.
