SEM is not a camera and the detector is not continuously image-forming like a CCD array or film. Unlike in an optical system, the resolution is not limited by the diffraction limit, fineness of lenses or mirrors or detector array resolution. The focusing optics can be large and coarse, and the SE detector is fist-sized and simply detects current. Instead, the spatial resolution of the SEM depends on the size of the electron spot, which in turn depends on both the wavelength of the electrons and the electron-optical system that produces the scanning beam. The resolution is also limited by the size of the interaction volume, the volume of specimen material that interacts with the electron beam. The spot size and the interaction volume are both large compared to the distances between atoms, so the resolution of the SEM is not high enough to image individual atoms, as is possible with transmission electron microscope (TEM). The SEM has compensating advantages, though, including the ability to image a comparatively large area of the specimen; the ability to image bulk materials (not just thin films or foils); and the variety of analytical modes available for measuring the composition and properties of the specimen. Depending on the instrument, the resolution can fall somewhere between less than 1 nm and 20 nm. As of 2009, The world's highest resolution conventional (≤30 kV) SEM can reach a point resolution of 0.4 nm using a secondary electron detector.[30] https://youtube.com/watch?v=e29F5n3ea0I&app=desktop

Keyword research and analysis involves three "steps": ensuring the site can be indexed in the search engines, finding the most relevant and popular keywords for the site and its products, and using those keywords on the site in a way that will generate and convert traffic. A follow-on effect of keyword analysis and research is the search perception impact.[13] Search perception impact describes the identified impact of a brand's search results on consumer perception, including title and meta tags, site indexing, and keyword focus. As online searching is often the first step for potential consumers/customers, the search perception impact shapes the brand impression for each individual.

It’s hard to believe that the Internet is now multiple decades old. Affiliate marketing has been around since the earliest days of online marketing. It’s a great solution for businesses that are risk-averse or don’t have the budget to spend on upfront marketing costs. Use affiliate marketing to build a new revenue stream for your ecommerce or B2B business.


Content is king. It always has been and it always will be. Creating insightful, engaging and unique content should be at the heart of any online marketing strategy. Too often, people simply don't obey this rule. The problem? This takes an extraordinary amount of work. However, anyone that tells you that content isn't important, is not being fully transparent with you. You cannot excel in marketing anything on the internet without having quality content.
Search engine marketing, or SEM, is meant to cover both search engine optimization (SEO) and paid search, also known as PPC (pay-per-click) or CPC (cost-per-click). From enhancing content with organic keywords to making sure a landing page meets Google AdWords quality guidelines, any optimization for the web traditionally fell under the umbrella of SEM. Over time, though, SEM has come to mean something much more specific. Popular usage now covers paid search exclusively, with SEO separated out. SEM still refers occasionally to paid search with a minor emphasis on SEO, but that’s even rarer than using the term properly. For clarity’s sake, I’ll replace SEM with “paid search” for the rest of this post.
Using Dr Dave Chaffey's approach, the digital marketing planning (DMP) has three main stages: Opportunity, Strategy and Action. He suggests that any business looking to implement a successful digital marketing strategy must structure their plan by looking at opportunity, strategy and action. This generic strategic approach often has phases of situation review, goal setting, strategy formulation, resource allocation and monitoring.[59]

What has changed in 2018 is that technology is allowing us to deliver on the purest essence of SEO. Whether via a mobile screen or a digital home assistant, our job is to ensure that our content can be discovered and served as seamlessly as possible. The addition of AI and machine learning into search algorithms means that there are no shortcuts to success; the best content starts to rise to the top over time.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("https://example.com/" is the same as "https://example.com"). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "https://example.com/fish" is not the same as "https://example.com/fish/". https://www.youtube.com/attribution_link?a=e29F5n3ea0I&u=watch?v=XXXXXX&feature=share
Baseline ranking assessment. You need to understand where you are now in order to accurately assess your future rankings. Keep a simple Excel sheet to start the process. Check weekly to begin. As you get more comfortable, check every 30 to 45 days. You should see improvements in website traffic, a key indicator of progress for your keywords. Some optimizers will say that rankings are dead. Yes, traffic and conversions are more important, but we use rankings as an indicator.
Before your start filming, set a music budget and research your local copyright laws. Copyright law can be very difficult to decipher, especially when you’re dealing with digital content. Bottom line: Most music isn’t free. If you use another artist’s music without permission or proper licensing, you risk video removal and legal action. In order to avoid copyright infringement, you’ll need to find royalty free tunes or pay a composer to create an original score. Royalty free songs aren’t free to use; they’re quality songs available for a single flat fee. This means you don’t have to worry about paying additional licensing fees or royalties in the future. YouTube, Pond5, and PremiumBeat are all great sites to find royalty free music.
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.”
If Google finds two identical pieces of content, whether on your own site, or on another you’re not even aware of, it will only index one of those pages. You should be aware of scraper sites, stealing your content automatically and republishing as your own. Here’s Graham Charlton’s thorough investigation on what to if your content ends up working better for somebody else. http://m.youtu.be/e29F5n3ea0I
Thanks to its viral nature, simple accessibility and built-in value, video marketing stands out as a smart way to approach content marketing in 2017 and beyond. Video marketing is an incredible way to create content that is personal and has a real impact on your audience. It has an incomparable ability to create emotion driven sales – and sales are always personal on some level. Buyers want to feel good about their choice, and video marketing, when done correctly, is the best way to create this feeling.

Ad groups allow for each campaign to be further subcategorized for relevance. In our hardware store example, one ad group could be for different types of rakes or varying models of leaf blowers. For the power tools campaign, one ad group might focus on power drills, while another could focus on circular saws. This level of organization might take slightly longer to set up initially, but the rewards – namely higher CTRs at lower cost – make this effort worthwhile in the long run.
The internet is full of business potential, but it is also rife with competition. In this situation, it becomes really tough to sell your products or services. Affiliate marketing can help you effectively promote your product on the web. By helping you reach out to a large potential customer base, affiliate programs help you to connect with millions of customers across the globe.
A custom YouTube end card or end screen is a graphic that appears near the end of a video. The graphic includes a clickable call to action. Many people use end cards to increase email newsletter subscriptions, promote resources or highlight other YouTube videos. You can only use end cards if you are in the YouTube Partner Program, on videos of 25 seconds or longer. Consider hiring someone to create a custom end card graphic to capture viewers’ attention.

The process of optimizing a website – as well as all the content on that website – so it will appear in prominent positions in the organic results of search engines. SEO requires an understanding of how search engines work, what people search for, and why and how people search. Successful SEO makes a site appealing to users and search engines. It is a combination of technical and marketing.
A pivotal component in a search engine marketing (SEM) campaign is a well-written ad. Other factors influence whether your ad will be displayed, but success is determined by whether your ad can inspire anybody to click through. Designing an inspiring ad, therefore, typically takes the creativity of an artist and the insights into your target audience’s psychology that user research experts can provide.

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.


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.
However, if you are seasoned online marketer, and you've built a substantial following, then marketing as an affiliate might be the right fit. Jason Stone from Millionaire Mentor has built a seven-figure business with affiliate marketing, while David Sharpe from Legendary Marketer has built up an eight-figure business by creating an army of affiliates that market products in collaboration with his team. http://www.youtube.com/v/7bNPg8UbhaE
