What is SEO and how it used?

SEO means ''Search Engine Optimization''.
 It is the process of getting web traffic from the “free,” “organic,” “editorial” or “natural” search results on search engines.
To understand what SEO really means, let's break that sentence down and look at the parts:

• Quality of traffic. You can attract all the visitors in the world, but if they're coming to your site because Google tells them you're a resource for Apple computers when really you're a farmer selling apples, that is not quality traffic. Instead you want to attract visitors who are genuinely interested in products that you offer.
• Quantity of traffic. Once you have the right people clicking through from those search engine results pages (SERPs), more traffic is better.
• Organic results. Ads make up a significant portion of many SERPs. Organic traffic is any traffic that you don't have to pay for.

Why is SEO important?

In today’s competitive market, SEO is more important than ever. Search engines serve millions of users per day looking for answers to their questions or for solutions to their problems.

If you have a web site, blog or online store, SEO can help your business grow and meet the business objectives.

Search engine optimization is essential because:

• The majority of search engines users are more likely to click on one of the top 5 suggestions in the results pages (SERPS), so to take advantage of this and gain visitors to your web site or customers to your online store you need to in the top positions.
• Users trust search engines and having a presence in the top positions for the keywords the user is searching, increases the web site’s trust.
• SEO is good for the social promotion of your web site. People who find your web site by searching Google or Yahoo are more likely to promote it on Facebook, Twitter, Google+ or other social media channels.
• SEO is important for the smooth running of a big web site. Web sites with more than one author can benefit from SEO in a direct and indirect way. Their direct benefit is increase in search engine traffic and their indirect benefit is having a common framework (checklists) to use before publishing content on the site.
• SEO can put you ahead of the competition. If two web sites are selling the same thing, the search engine optimized web site is more likely to have more customers and make more sales
