This method requires an SEM image obtained in oblique low angle lighting. The grey-level is then interpreted as the slope, and the slope integrated to restore the specimen topography. This method is interesting for visual enhancement and the detection of the shape and position of objects ; however the vertical heights cannot usually be calibrated, contrary to other methods such as photogrammetry.

Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
It's clear that online marketing is no simple task. And the reason why we've landed in this world of "expert" internet marketers who are constantly cheerleading their offers to help us reach visibility and penetrate the masses is because of the layer of obscurity that's been afforded to us in part thanks to one key player: Google. Google's shrouded algorithms that cloud over 200+ ranking factors in a simple and easy-to-use interface has confounded businesses for well over a decade now.
This is both a challenge and a great opportunity. The challenge is because the organic spots aren’t what they used to be – there used to be ten organic spots on the first page to compete for – and only five above the fold, (which refers to the vertical limitations of a user’s screen and the amount of content one can view without scrolling). Now there might be local search results, news releases, images and video included in the results – many of those above the fold. What’s the new number one spot? Is it the first local result, news release, or organic listing?
Other Way of Measuring Success: The video features a call-to-action for viewers to download an accompanying content offer (a thought leadership guide we published). We tracked downloads of the content offer that were driven by video views as well as overall engagement of the video itself: How long did viewers stick around? Where did they drop off? Did they re-watch it?
Marketers understand that this "hunt mode" means that the searcher may very well be at the beginning, middle, or end stages of the buying cycle. When someone is researching a product or service to satisfy an immediate or future need they are in an unusual state: they desire relevant information and are open to digesting and acting on the information at their fingertips, all made possible by a search engine. This makes search engine results some of the best sources of targeted traffic, whether this traffic originates from "organic" unpaid search listings or paid advertising listings.
Companies that employ overly aggressive techniques can get their client websites banned from the search results. In 2005, the Wall Street Journal reported on a company, Traffic Power, which allegedly used high-risk techniques and failed to disclose those risks to its clients. Wired magazine reported that the same company sued blogger and SEO Aaron Wall for writing about the ban. Google's Matt Cutts later confirmed that Google did in fact ban Traffic Power and some of its clients.

SEM is the wider discipline that incorporates SEO. SEM includes both paid search results (using tools like Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay per click (particularly beneficial for local providers as it enables potential consumers to contact a company directly with one click), article submissions, advertising and making sure SEO has been done. A keyword analysis is performed for both SEO and SEM, but not necessarily at the same time. SEM and SEO both need to be monitored and updated frequently to reflect evolving best practices.
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.
Online marketing is the practice of leveraging web-based channels to spread a message about a company’s brand, products, or services to its potential customers. The methods and techniques used for online marketing include email, social media, display advertising, search engine optimization, and more. The objective of marketing is to reach potential customers through the channels where they spend time reading, searching, shopping, or socializing online.
In the last 10 years, the digital landscape has changed significantly. People are phasing out desktop and laptop computers to search the web and interact with content. Instead, they are picking up their mobile phones and tablets. What’s more, digital technology is cheaper today than it’s ever been before; there are virtually no boundaries on how, when and where people can interact with content.
The most common imaging mode collects low-energy (<50 eV) secondary electrons that are ejected from the k-shell of the specimen atoms by inelastic scattering interactions with beam electrons. Due to their low energy, these electrons originate within a few nanometers from the sample surface. The electrons are detected by an Everhart-Thornley detector, which is a type of scintillator-photomultiplier system. The secondary electrons are first collected by attracting them towards an electrically biased grid at about +400 V, and then further accelerated towards a phosphor or scintillator positively biased to about +2,000 V. The accelerated secondary electrons are now sufficiently energetic to cause the scintillator to emit flashes of light (cathodoluminescence), which are conducted to a photomultiplier outside the SEM column via a light pipe and a window in the wall of the specimen chamber. The amplified electrical signal output by the photomultiplier is displayed as a two-dimensional intensity distribution that can be viewed and photographed on an analogue video display, or subjected to analog-to-digital conversion and displayed and saved as a digital image. This process relies on a raster-scanned primary beam. The brightness of the signal depends on the number of secondary electrons reaching the detector. If the beam enters the sample perpendicular to the surface, then the activated region is uniform about the axis of the beam and a certain number of electrons "escape" from within the sample. As the angle of incidence increases, the interaction volume increases and the "escape" distance of one side of the beam decreases, resulting in more secondary electrons being emitted from the sample. Thus steep surfaces and edges tend to be brighter than flat surfaces, which results in images with a well-defined, three-dimensional appearance. Using the signal of secondary electrons image resolution less than 0.5 nm is possible.
The impact on who you hire. If you’re looking for an SEO specialist and using SEM terminology, you’ll be inundated with applicants who have more experience with paid search than with SEO. You may also find an SEO pro with paid search experience, but I don’t recommend having a single person handle both. For the best results, you need to focus on one or the other. Some specialists can compartmentalize and not let paid and organic-keyword research taint each other, but many have trouble—upping the risk that your pair of keyword strategies will meld into one.
Optimize your lead capture form. Lead generation forms aren’t just a critical part of landing page design; if you get it wrong, people won’t bother filling it out. There is no standard length for sign-up forms: website review service WooRank has found that shorter forms generally get more responses, but people who take time to complete a longer form tend to be higher-quality leads. As with a CTA, only testing can tell for sure what your particular audience will do.

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.
Anyone looking towards a career in digital marketing should have a good grasp not only on how SEO and SEM function in today’s current digital atmosphere, but they should be looking to how both will change as we become more and more reliant on technology. Having a solid grasp of how each of these are involved in digital marketing campaigns will be especially crucial in the digital marketplace in the coming years.

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. https://youtube.com/watch?v=e29F5n3ea0I&app=desktop
Data-driven advertising: Users generate a lot of data in every step they take on the path of customer journey and Brands can now use that data to activate their known audience with data-driven programmatic media buying. Without exposing customers' privacy, users' Data can be collected from digital channels (e.g.: when customer visits a website, reads an e-mail, or launches and interact with brand's mobile app), brands can also collect data from real world customer interactions, such as brick and mortar stores visits and from CRM and Sales engines datasets. Also known as People-based marketing or addressable media, Data-driven advertising is empowering brands to find their loyal customers in their audience and deliver in real time a much more personal communication, highly relevant to each customers' moment and actions.
Advertising with Google won't have any effect on your site's presence in our search results. Google never accepts money to include or rank sites in our search results, and it costs nothing to appear in our organic search results. Free resources such as Search Console, the official Webmaster Central blog, and our discussion forum can provide you with a great deal of information about how to optimize your site for organic search.
Structured data21 is code that you can add to your sites' pages to describe your content to search engines, so they can better understand what's on your pages. Search engines can use this understanding to display your content in useful (and eye-catching!) ways in search results. That, in turn, can help you attract just the right kind of customers for your business.
At this point, the consumer is weighing their options and deciding on the purchase. Therefore, the goal of this kind of video is to make your audience visualize themselves using your product or service — and thriving. There’s a reason 4X as many customers would rather watch a video about a product than read about it. Videos are able to display functionality and leverage emotions in ways a product description never could.
Google’s Accelerated Mobile Project (AMP) will gain even more popularity. AMP is a collaboration between developers and other industry professionals to create a massive open source library that offers users more opportunity to create quick and smooth mobile-friendly web pages. This is one area where we’ll be seeing the death of slow-loading pages that rank low. The use of AMP has resulted in huge increases in mobile searches and traffic from major publications such as the Washington Post and Slate. https://m.youtube.com/e/7bNPg8UbhaE
