Search engine marketing - Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate Search engine optimization, which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings.
Paid inclusion is a search engine marketing method in itself, but also a tool of search engine optimization, since experts and firms can test out different approaches to improving ranking and see the results often within a couple of days, instead of waiting weeks or months. Knowledge gained this way can be used to optimize other web pages, without paying the search engine company.
For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
Affiliate marketing - Affiliate marketing is perceived to not be considered a safe, reliable and easy means of marketing through online platform. This is due to a lack of reliability in terms of affiliates that can produce the demanded number of new customers. As a result of this risk and bad affiliates it leaves the brand prone to exploitation in terms of claiming commission that isn't honestly acquired. Legal means may offer some protection against this, yet there are limitations in recovering any losses or investment. Despite this, affiliate marketing allows the brand to market towards smaller publishers, and websites with smaller traffic. Brands that choose to use this marketing often should beware of such risks involved and look to associate with affiliates in which rules are laid down between the parties involved to assure and minimize the risk involved.
Paid search gives you a much higher level of control when it comes to the searcher’s ability to find your website on the SERPs. With paid search advertisers tell Google for which search terms they want their ads to show. Google then shows their ads and takes their money when someone clicks on their advertisement and is directed to their website (hence pay per click). Advertisers do not pay to show ads for keywords, but they do pay when searchers click on them; the amount you pay is called cost-per-click (CPC).
This refers to your ability to rank for certain keywords. For instance, say you sell shoes online, you will need to optimize your site, backlinks, website speed and much more so that you can “rank” high for certain keywords that are highly relevant to your business. Relevant keywords may include “buy shoes,” “shoe sale,” “where to buy shoes,” and so on. Once you can rank high (top page) for these keywords, you will enjoy an increase in traffic and business as a result.
