Difference Between SEO and SEM
SEO vs SEM
SEO (Search Engine Optimization) and SEM (Search Engine Marketing) are two very common buzz words that are used when you want to promote a web site or a product. SEM is simply marketing by aiming to gain visibility in search engine results. This can be done in a variety of ways including: paid placement, contextual advertising, paid inclusion, and, of course, via SEO. So the main difference between SEO and SEM is that SEO is simply one aspect of the much bigger SEM.
SEO is the practice of optimizing a site’s content so that it would rank higher in search engines. This mostly involves the proper distribution of keywords, increasing the number of backlinks, and making it easier for robots to properly index the site. A robot, or spider, is the software used by search engines like Google and Yahoo to index the contents of a page. The index is then used by the search engine to determine how relevant that page is to what the user is searching for.
Other aspects of SEM, like paid placement and paid inclusion, require an additional cash outlay but are not really essential to the site. On the other hand, good SEO should also include making content that is relevant to the user. Even if you manage to get a user to your site with the other SEM methods, he would not stay if there is no usable content on your site. In this regard, it is easy to conclude that SEO is the cheaper option as you would be hitting two birds with one stone. Since you would need content anyway, making sure that it is optimized for the search engine is just a smaller adjustment.
The main disadvantage of SEO is speed. While other SEM styles get results instantly, employing purely SEO produces results in a delayed fashion. This is because it takes some time before the crawlers go through your pages and index them. It is also not advisable for pages that constantly change content because the indexed data may no longer reflect the true content of the page.
To conclude, SEM is a broad topic that covers a lot. SEO is only one part of it, albeit it is the important aspect. With limited resources, SEO is the best option to pursue. But if you want results quickly without concern for the expense, using the full array of SEM techniques should get you instant results.
