Search engine optimization (SEO) is the process of affecting the visibility of a website or a portal in a search engine’s “natural” or un-paid (“organic”) search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine’s users. SEO may target different kinds of search, including image search, local search, video search, academic search, news search and industry-specific vertical search engines.
As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

Search engine optimization and promotion is challenging at best. It's not just a simple matter of adding a few tags that contain your important keywords. It is an art-and-a science-since it is applying creative techniques to an in-dept study of the search engines,directories, etc.

1. The Results are Low Cost (In Comparison to Adwords and PPC)
Organic listings are essentially free. When you are listed at the top, you don’t need to pay per click or allocate a budget for advertising, one of the main benefits of SEO is that it is the gift that keeps on giving. With a little bit of effort (and some money upfront to pay for SEO costs) you can watch your website get consistent traffic. You don’t have to pay $10 for every person who clicks on your ad. Unlike paid ads, your traffic will not drop to nothing when it stops. SEO gets rid of the need to have thousands of ads across the web.

2. Definite Increase in Traffic
With Analytics and reporting tools, you’ll see a clear cut increase in traffic. This is a definite way to maximize your business efforts. SEO will give you results (not immediately but rather quickly) and as soon as you start your SEO efforts, traffic will increase at a steady rate. Using tools to track traffic to your site you can clearly watch as more people visit your site and sales go through the roof.

3. Higher Brand Credibility, People Trust Google
People trust that the first listing in google is a reputable company, by doing SEO, your website becomes THE brand name. You’re the guy the competitors want to beat. The further back you are in rankings on Google the more people are skeptical about your website. If google has a spot dedicated to you at the top especially if it is a top tier listing with other subpages listed below the main home page it gives your website credibility that no ad can top. Ads can often be seen as annoying and many people have ad blockers installed on their browsers.

4. Better ROI (Return on Investment) Than Normal Ads
When you buy 1000 visitors from a paid ad, 2% of those visitors might convert into a sale. When you get 1000 clicks from SEO, 4% of those visitors will convert into a sale, leading to a better return on investment. This higher conversion rate is just another one of the benefits of SEO that cannot be matched by any other form of marketing. Google searches actually get people who searched for the tag in your website. These people are actually looking for your product. Ads can be from anyone. Many people may misclick on an ad. A hit from google is much more valuable over a hit from an ad.

5. Your Competitors Are Doing It
SEO is a rising field and it is gaining ground. More people are starting to realize that the benefits of SEO are extremely high. Your competitors know this and are starting to take advantage of it. If your competitors are using it then they will appear before you on Google and get all those hits that can lead to sales before your website will. Even if your site offers better services or prices. Hiring a better SEO company or investing in a skilled SEO Staff could be exactly what your company needs to rank above your competitors in the Google rankings.

6. Take Your Business to the Next Level
SEO can bring it thousands upon thousands of visitors to your website a day. This may put your company in a position of needing to expand to a larger web server to accommodate the traffic and sales to your website. Your customers may recommend you a product or service that they were looking for when they visited your website. SEO is a really great investment for your company and could be what you need to take it to the next level.

7. 250 Million websites on the web, SEO makes you stand out
There are well over 250 million websites on the web. It can be pretty hard to make a name for yourself with that many out there. Especially if your product or service is highly competitive. Using SEO will make your brand stand out from the rest and can easily be the boost that you need to see your sales go through the roof.

8. 60% Of Clicks Go to the First Result
This means that only 40% of clicks are left for the second through the millionth result on google for the keyword. Securing that top spot on Google is a sure fire way to gain thousands upon thousands of visitors. SEO is certainly the tool needed to gain that top spot as well. For a small up front investment you are looking at potentially millions of sales.

9. You’ll Have Access to Data
What data you may ask? You get customer data. You can discover new products to expand to by looking at keyword data and seeing what people are searching the most for. You can use this to your advantage and find a high search volume keyword with low competitiveness and although that may be hard to find it has the potential to bring in thousands of sales per month to your website. Customer data is extremely valuable in this business and is not that hard to come by with the right tools. Manipulating it to your advantage can be exponentially beneficial for your business.

10. The Results are Permanent
Unlike advertisements the affects of SEO are permanent. They don’t suddenly stop if you stop paying for them. Of course you will need a little upkeep to maintain that top 1st spot ranking, but if you can get that top spot chances are it will be quite difficult for it to get taken away.
