Organic SEO (Search Engine Optimization) is the use of website techniques to improve your website's search engine results. Search engines use specific algorithms to determine what website will be ranked higher for a particular query in search results. These algorithms are constantly evolving along with the internet, so it is important to stay abreast of SEO techniques. Organic SEO results typically take longer to mature than SEM results. Some examples of organic SEO techniques include using relevant page titles, keywords with keyword analysis, link building, image tagging and writing content relevant for human readers.

On the other hand, paid SEM (Search Engine Marketing) involves advertising campaigns such as Pay Per Click (PPC). This type of advertising may be featured in a banner or in the margins of websites or search engines. A company may gain immediate results with paid SEM campaigns. However, the website must be informative, well organized, well designed and capture the attention of the viewer within the first three seconds.
