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 (SEO), 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.
Let’s assume that your goal is customer acquisition. You know you’ve acquired a customer when you make a sale. So, you’d set up a sales conversion goal. To do that, click on “New Goal.” In the goal setup section, you can either select “template” or “custom.” Custom gives you more flexibility, so go with that option. Go on to the “goal description.” This is where you define your goal by naming it and selecting the type. For customer acquisition, you want to select “Destination.”
Search engines use complex mathematical algorithms to guess which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
This community is full of opportunities if you're a fashion-based retailer. One of the major advantages is the fact that they add links to each of the products that they feature within their outfits - the links go directly to product pages. This is the holy grail for ecommerce SEO, and the traffic those links will bring through will convert at a very high rate.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
