If you searched for "Miserable Failure" in Google, the top result returned was the official website of George Bush. You can rest assured; George was not sitting there tweaking the "meta tags" within his website to include that keyword term. In fact, I highly doubted the term "Miserable Failure" appeared within his website content anywhere.
What happened was that thousands of other websites started linking to George's website using the exact term "Miserable Failure" as the "Anchor Text" of the hyperlinks. Due to the nature of Google's computer algorithm – and the importance it places on incoming links (and specifically the extremely large amount of weight that theyave to "anchor text" at the time) – it started to recognize that this is what George's website was related to.
Sometimes it gained a # 1 position for this term linking linking alone. Pretty funny stuff really. There are quite a few well known instances of this happening. Another one was a competition between people within the SEO industry to see who could rank for "coolest guy on the planet". If you want more examples, just go to Google and type in "Google Bomb" however this should show you how important incoming links were (and still very much are) as a primary search engine ranking factor.
At this same time you could also use a specific search syntax in Google to see exactly how many back links any given website had, and specifically where those links were. Form an SEO perspective, it was dead easy to "reverse engineer" why the top ranking websites were ranking like they were. You could simply manipulate the keyword density of your content pages, and implement a similar link building campaign as close to the high ranking websites as possible. Hey presto – although it did require work – top rankings would not be far away.
As you can imagine, with the introduction of the importance of incoming links, experienced webmasters we're also able to "game" that to their advantage as well. The "Google Bomb" mentioned was a prime example of how this link ranking factor could be "gamed". However, placing more importance on incoming links as a primary ranking factor was the "lesser of two evils" in the way in which Google could rank websites.
It is easy enough for any old webmaster to manipulate the internal components of their own websites (keyword density etc). …

We live in the world where the popularity of PLC endures due to the automated industry. A few decades back, PLC was an only viable option to control industrial automation applications.
Even though, today you can find various choices such as panel PCs, industrial PCs and soft PLCs that have the same functionality as PLC/HMI combination.
By checking online PLC support, you can find everything you need when it comes to PLCs. Even though new control options emerged due to technological advancement, there are still numerous reasons why industry uses PLCs.
Peace Of Mind
Both PCs and PLCs have come a long way from their beginnings. Today, there is a significant difference in how these control options evolved especially when it comes to industrial automation. The evolution of PLCs means that you can do and support products for long periods of time, for both software and hardware.
It means that when you take an application program in 20-year-old PLC, you will be able to transfer it straight to a brand new one. You can also install the latest controller and backup all applications that you’ve run on old PLC almost immediately.

You can find numerous industries where the level of support is not desirable but a base requirement. For example, in the water industry, there is a talk, that framework suppliers should assure support of control system for at least 20 years.
Of course, the control hardware will usually change over years, but you will have peace of mind knowing that you can back up the exact software you’re using now to a brand new controller.
Reliable and Robust
The latest industrial PC will provide you a stable platform that shares more significant power when compared with a desktop PC. However, when compared with PLC, it doesn’t have the same durable features.
Even though you have real-time operating systems that run on Windows similar to PCs for the general population, industry PC will provide the same level of performance and robustness that you will get from PLC.
If you use PC in complete isolation, then the reliability is the essential thing that will provide you the durable outcome. However, when it comes to the controller, you will have to connect peripherals, I/O network, and other components so that you can load it into the PC.

The question is whether drivers of all products are reliable as PLC? It is unlikely, which is why most clashes and problems happen and could interfere with production line when drivers get updated. Therefore, it is inevitable that industrial PC will crash and you know what that means for the entire control process.
Besides, you don’t have to reboot a PLC because the software is durable and unable to crash.
The best selling PLCs will provide you with a wide array of applications and more than 40 I/O ports. In these applications, PLC is …
