Magnification in an SEM can be controlled over a range of about 6 orders of magnitude from about 10 to 500,000 times. Unlike optical and transmission electron microscopes, image magnification in an SEM is not a function of the power of the objective lens. SEMs may have condenser and objective lenses, but their function is to focus the beam to a spot, and not to image the specimen. Provided the electron gun can generate a beam with sufficiently small diameter, an SEM could in principle work entirely without condenser or objective lenses, although it might not be very versatile or achieve very high resolution. In an SEM, as in scanning probe microscopy, magnification results from the ratio of the dimensions of the raster on the specimen and the raster on the display device. Assuming that the display screen has a fixed size, higher magnification results from reducing the size of the raster on the specimen, and vice versa. Magnification is therefore controlled by the current supplied to the x, y scanning coils, or the voltage supplied to the x, y deflector plates, and not by objective lens power.
Another one of the benefits of SEM is that people who see your PPC ads are those most likely to want to buy your product or service. PPC ads require you to choose a geographic location and specific search queries to target. As a result, you can be sure that anyone who clicks on your ad is not arbitrarily surfing the web, but rather, is looking for your product or service and in a position to do so.

Achieving video marketing success is sometimes seen as expensive and hard to do. Content creators are often disappointed with the amount of effort it takes to produce an online video versus the online exposure and visibility that it actually receives. What if your video could appear extremely high in the search engines and thousands of views could be obtained for an extremely low price point?
7. Keyword research. Specific target keywords aren’t as important for SEO success as they used to be, now that Google search is fueled by semantic and contextual understanding, but you should still be able to identify both head keyword (short, high-volume keywords) and long-tail keyword (longer, conversational, low-volume keywords) targets to guide the direction of your campaign. http://m.youtu.be/7bNPg8UbhaE
