A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the detected signal to produce an image. SEM can achieve resolution better than 1 nanometer. Specimens are observed in high vacuum in conventional SEM, or in low vacuum or wet conditions in variable pressure or environmental SEM, and at a wide range of cryogenic or elevated temperatures with specialized instruments.
Internet marketing is not a singular approach to raising interest and awareness in a product. Because of the vast number of platforms the Internet creates, the field encompasses several disciplines. It involves everything from email, to Search Engine Optimization (SEO), to website design, and much more to reach an ever-evolving, ever-growing audience. (See also Web Marketing)

The scanning electron microscope (SEM) uses a focused beam of high-energy electrons to generate a variety of signals at the surface of solid specimens. The signals that derive from electron-sample interactions reveal information about the sample including external morphology (texture), chemical composition, and crystalline structure and orientation of materials making up the sample. In most applications, data are collected over a selected area of the surface of the sample, and a 2-dimensional image is generated that displays spatial variations in these properties. Areas ranging from approximately 1 cm to 5 microns in width can be imaged in a scanning mode using conventional SEM techniques (magnification ranging from 20X to approximately 30,000X, spatial resolution of 50 to 100 nm). The SEM is also capable of performing analyses of selected point locations on the sample; this approach is especially useful in qualitatively or semi-quantitatively determining chemical compositions (using EDS), crystalline structure, and crystal orientations (using EBSD). The design and function of the SEM is very similar to the EPMA and considerable overlap in capabilities exists between the two instruments.
Content marketing is more than just blogging. When executed correctly, content including articles, guides (like this one), webinars, and videos can be powerful growth drivers for your business. Focus on building trust and producing amazing quality. And most of all, make sure that you’re capturing the right metrics. Create content to generate ROI. Measure the right results. This chapter will teach you how.
The largest search engines, Google, Bing and Yahoo, each have fairly simple programs to get started. You determine the key words or search phrase as well as the amount you are willing to spend (per click and/or per day). Most of them offer simple programs that require filling out a form and putting a certain amount of money down as credit. Like anything new, start small with paid SEM and add complexity (and budget) as you learn more and see results over time.
You’ve launched an amazing product or service. Now what? Now, you need to get the word out. When done well, good PR can be much more effective and less expensive than advertising. Regardless of whether you want to hire a fancy agency or awesome consultant, make sure that you know what you’re doing and what types of ROI to expect. Relationships are the heart and soul of PR. This chapter will teach you how to ignore the noise and focus on substantive, measurable results.
One of the most enduring misconceptions about search engine marketing is that whomever has the largest advertising budget wins. Although a larger advertising budget can certainly be advantageous, especially when targeting highly competitive keywords, but it’s far from a requirement for success with search engine marketing. This is because all ads go through a process known as the ad auction before appearing alongside search results. For the purposes of this explanation, we’ll be focusing on the ad auction in Google AdWords.
Search engine optimization (SEO) is often about making small modifications to parts of your website. When viewed individually, these changes might seem like incremental improvements, but when combined with other optimizations, they could have a noticeable impact on your site's user experience and performance in organic search results. You're likely already familiar with many of the topics in this guide, because they're essential ingredients for any web page, but you may not be making the most out of them.
Test and Listen. Think you can record the perfect voice over in just one take? Think again! Invest in a good pair of headphones and keep an eye on your audio quality throughout the recording process. It’s easier to get a new take of audio than trying to fix it during the editing process. We recommend running through your script a few times, especially the first few paragraphs, to ensure that your voice is fully warmed up. If you hear popping or hissing sounds, try standing further away from the mic or invest in a pop filter.
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.
9. Troubleshooting and adjustment. In your first few years as a search optimizer, you’ll almost certainly run into the same problems and challenges everyone else does; your rankings will plateau, you’ll find duplicate content on your site, and you’ll probably see significant ranking volatility. You’ll need to know how to diagnose and address these problems if you don’t want them to bring down the effectiveness of your campaign.
SEO today is in many ways still a focused and specific discipline requiring experience and expertise. However, it has become much more dependent on, and integrated with, other digital marketing channels which is a good thing allowing for the scaling of content and resources. As most marketing is now digital, SEO has a proper seat at the table and place as a lead organic traffic driver contributing to end business goals.
One of the earliest adopters of Internet marketing in the world of Fortune 500 companies was the Coca-Cola Corporation. Today, this huge purveyor of soft drinks has one of the strongest online portfolios in the world. More than 12,000 websites link to the Coca-Cola homepage, which itself is a stunning display of Internet savvy. Their homepage alone sports an auto-updating social network column, an embedded video, a unique piece of advertising art, frequently rotating copy, an opt-in user registration tab, tie-in branding with pop culture properties, and even a link to the company's career opportunities page. Despite how busy that sounds, the Coca-Cola homepage is clean and easy to read. It is a triumph of Internet marketing for its confidence, personality, and professionalism.
One possible application is measuring the roughness of ice crystals. This method can combine variable-pressure environmental SEM and the 3D capabilities of the SEM to measure roughness on individual ice crystal facets, convert it into a computer model and run further statistical analysis on the model. Other measurements include fractal dimension, examining fracture surface of metals, characterization of materials, corrosion measurement, and dimensional measurements at the nano scale (step height, volume, angle, flatness, bearing ratio, coplanarity, etc.).
Advocates on either side could argue one is more effective than the other, but I like to view high-quality SEO as a prerequisite for high-quality SEM. SEO lays the foundation for SEM through well-optimized content that prospects and customers find helpful. Without landing pages, web pages and blog content optimized for search, your SEM efforts will fall flat due to poor quality, and visibility in the SERPs will be extremely difficult. Organic SEO is also less costly long-term as you establish search credibility, as long as you maintain it with the consistent creation of quality content and social media usage.

The truth? Today, rising above the noise and achieving any semblance of visibility has become a monumental undertaking. While we might prevail at searching, we fail at being found. How are we supposed to get notice while swimming in a sea of misinformation and disinformation? We've become immersed in this guru gauntlet where one expert after another is attempting to teach us how we can get the proverbial word out about our businesses and achieve visibility to drive more leads and sales, but we all still seem to be lost.
Paid search advertising has not been without controversy and the issue of how search engines present advertising on their search result pages has been the target of a series of studies and reports by Consumer Reports WebWatch. The Federal Trade Commission (FTC) also issued a letter in 2002 about the importance of disclosure of paid advertising on search engines, in response to a complaint from Commercial Alert, a consumer advocacy group with ties to Ralph Nader. http://youtube.com/e/7bNPg8UbhaE?app=desktop
Did you know that 85% of Facebook video is watched with no sound? Many people watch videos in places where they can't turn the sound up, or where there's background noise. Those are two important reasons why video captions matter. And, of course, video captions matter for accessibility. Include captions, and you will improve you click-through rate as those with hearing loss or impairment can still understand your video content. Captions also help with SEO by providing text that search engines can find.
As we’ve been told by the Google rater’s guide, we ideally want to focus upon building sites that raters might see as involving Expertise, Authoritativeness, and Trustworthiness. A recent Google patent told us that it might look at search results to gauge the authoritativeness of pages in search results, and if pages within those results don’t meet a specific threshold of authoritativeness, Google may perform a search on a related query to find other authoritative search results, which could then be blended into search results for that initial query.
Keywords can also guide other promotional efforts—even business decisions. In the “Beginner’s Guide to SEO,” the team at Moz wrote: “The usefulness of this intelligence cannot be overstated; with keyword research, you can predict shifts in demand, respond to changing market conditions, and produce the products, services, and content that web searchers are actively seeking.”
The answer, at its basis, is largely what I convey in a great majority of my books about search engine optimization and online marketing. It all boils down to one simple concept: add tremendous amounts of value to the world. The more value you add, the more successful you become. Essentially, you have to do the most amount of work (initially at least) for the least return. Not the other way around.
Digital marketing is also referred to as 'online marketing', 'internet marketing' or 'web marketing'. The term digital marketing has grown in popularity over time. In the USA online marketing is still a popular term. In Italy, digital marketing is referred to as web marketing. Worldwide digital marketing has become the most common term, especially after the year 2013. http://youtube.com/watch?feature=youtu.be&v=e29F5n3ea0I
In some contexts, the term SEM is used exclusively to mean pay per click advertising, particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting. https://www.youtube.com/watch?v=7bNPg8UbhaE
On the other hand, a website can have a fantastic paid search strategy in place and experience short-term gains in traffic and click-through rates (CTR) while missing SEO optimization completely. In this case, growth will be fast and visitors/clicks will be generated through a more diverse set of keywords—but it may cost quite a bit of money that would be more effective elsewhere. http://youtube.com/watch?v=e29F5n3ea0I&app=desktop
Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
The nature of the SEM's probe, energetic electrons, makes it uniquely suited to examining the optical and electronic properties of semiconductor materials. The high-energy electrons from the SEM beam will inject charge carriers into the semiconductor. Thus, beam electrons lose energy by promoting electrons from the valence band into the conduction band, leaving behind holes.
Search engine marketing is a method of promotion and advertising to help companies’ content rank higher among search engine traffic. Like search engine optimization (SEO), search engine marketing (SEM) helps companies improve the way content is ranked by search engines. SEM helps companies bring their products and services to the attention of audiences who are ready to buy.
Smartphone - In this document, "mobile" or “mobile devices" refers to smartphones, such as devices running Android, iPhone, or Windows Phone. Mobile browsers are similar to desktop browsers in that they can render a broad set of the HTML5 specification, although their screen size is smaller and in almost all cases their default orientation is vertical.
A compelling call to action (CTA). Whether you want a visitor to make a purchase, give you their contact information, or download a file, the CTA should be easy to spot and optimized to get the most conversions. Will your mailing list get more sign-ups with a button that says “subscribe now,” “register today,” or “sign me up?” You may need to do some testing to find out.
As an alternative to simply replacing each grey level by a color, a sample observed by an oblique beam allows researchers to create an approximative topography image (see further section "Photometric 3D rendering from a single SEM image"). Such topography can then be processed by 3D-rendering algorithms for a more natural rendering of the surface texture
While Facebook’s main purpose isn’t for watching and sharing videos, the site is making a smart move by investing more in the medium. Facebook is a great place to share top-of-funnel video content that is worthy of being shared. Think about keeping video content here fairly short, attention-grabbing enough to prevent scrolling, and if possible, create your content so the message can be relayed and enjoyed even without sound. If you do this well, the site’s network of users essentially act like brand ambassadors, helping to disseminate your content for you.
