SEO is a marketing strategy business owners use to get web pages on their website to rank on the top of Search Engine Results Page’s (SERP’s).
SEM stands for Search Engine Marketing. SEM is more of a broad view of your overall online marketing strategy. However, when talking with digital marketing professionals, the term SEM usually refers to pay per click advertising.
SEO and SEM actually work hand in hand because without a clear focus of the organic keywords that are delivering the best results in searches, you can actually waste a lot of your pay per click budget on keywords that are either irrelevant or don’t deliver optimal results.
