Sample preparation can be minimal or elaborate for SEM analysis, depending on the nature of the samples and the data required. Minimal preparation includes acquisition of a sample that will fit into the SEM chamber and some accommodation to prevent charge build-up on electrically insulating samples. Most electrically insulating samples are coated with a thin layer of conducting material, commonly carbon, gold, or some other metal or alloy. The choice of material for conductive coatings depends on the data to be acquired: carbon is most desirable if elemental analysis is a priority, while metal coatings are most effective for high resolution electron imaging applications. Alternatively, an electrically insulating sample can be examined without a conductive coating in an instrument capable of "low vacuum" operation.
Web design is a very technical field that requires high literacy in many different kinds of software, including image editing and website architecture programs. A designer should be comfortable with computer “languages” like HTML and stay up to date on new technological developments. The designer is also an artist, so he or she should also have a firm grasp on aesthetics, visual continuity, and image composition.

Sometimes SEO is simply a matter of making sure your site is structured in a way that search engines understand.
However, with all of these so-called modern conveniences to life, where technology's ever-pervading presence has improved even the most basic tasks for us such as hailing a ride or ordering food or conducting any sort of commerce instantly and efficiently, many are left in the dark. While all of us have become self-professed experts at consuming content and utilizing a variety of tools freely available to search and seek out information, we're effectively drowning in a sea of digital overload.
What is search engine optimization, then? It's not secrets or tricks — just ranking methodologies to follow in order to help a site that offers value to users beat the competition in search results. Today, you must be committed not just to optimizing your domain, but also to making it a quality site that attracts links naturally and is worthy of ranking.
