The Difference Between SEO and SEM

SEO is an acronym for Search Engine Optimization. This is how a website purposefully designs it content, including their titles, content and meta tags, for the sole purpose of getting the attention of search engines like Google, Yahoo and the lesser known Bing. What SEO wants to achieve is an organic or natural flow of traffic to their websites that is not bought or paid for like we do when we pay for advertising. A search engine result is free.SEM is an acronym for Search Engine Marketing. It is a concept often associated with SEO, sometimes even confused with SEO. They have some goals in purpose but are very different in technique. SEM has come about because large search engine websites like Google have offered fees to show case ads on the top of their page listing. These are pay per click or PPC ad campaigns. SEM is closer to traditional advertising in that you pay for the direct exposure you are receiving. SEM has made it possible to be a website with high visitor content just because they pay more to be advertised and promoted by Google. Both SEM and SEO are sets of strategies to bring in visitors. Except you pay up front for SEM, it is a direct advertising strategy. While with SEO, you look for indirect ways to get noticed.Optimizing a website for search engines, will mean evaluating particular keywords and keyword phrases the internet users may type into search engines to look for service and products that an ecommerce based business may offer. The grit of SEO is editing website content with keywords. Including keywords and keyword phrases in tags and meta tags. Even links and HTML is edited to suit SEO. HTML and links are worked out in a way to get the website user to move a certain way within your website. Ideally, the website visitor is presented with links around the website, going from page to page to read information they are interested in. This design makes it so the website user does not leave the website immediately.

Mobile Computing

Mobile computing refers to the use of any kind of computer in a moving environment. The motion may be of the device itself, as in laptops, palmtops, wearable computers, and mobile phones; or it may refer to the dynamics of the computing process, as in digital cameras, podcasters and MP3 players. Mobile computing devices generally use wireless technologies such as LAN, Wi-Fi, GPRS and the more recently introduced MAN.Mobile computing can be broadly classified into two categories – portable computing and mobility computing. Portable computing actually refers to wired communication. Portable devices themselves are movable, but in order to access them one needs to connect them to a network port. That means, portable computing devices can be carried to wherever there is a network port available. Mobility computing is also called simply mobile computing nowadays. This is true wireless communication. Not only are the devices movable, but they can also be accessed from almost anywhere. Today, portable computing is almost on the verge of extinction; mobile computing has made its foray into almost every aspect of human life.
