Scraping the Bottom of the Barrel - The Perils of Online Article Marketing

Many online article marketers so desperately wish to succeed, they want to dump corporate life and work for themselves out of their home. They decide they are going to create an online money making website. Therefore, they look around to see what everyone else is doing, and watch the methods others use to attract online buyers, and then they mimic their marketing, their strategies, and their business models.

Still, if you are copying what other people (less ethical people) are doing in online article marketing, those which are scraping the bottom of the barrel and using false advertising and misrepresentations, then all you are really doing is perpetuating distrust on the Internet. Therefore, you are hurting everyone, including people like me. You must realize that people like me don't appreciate that.

Let me give you a few examples of some of the things going on out there, thing that are being done by people who are ethically challenged. Far too many people write articles and then on their byline they send the Internet surfer or reader of the article to a website that has a squeeze page. The squeeze page has no real information on it, rather it asks for their name and e-mail address.

If the would-be Internet surfer is unwise enough to type in their name and email address they will be spammed by e-mail, receiving various hard-sell marketing pieces. Then, if the Internet Surfer does decide to put in their e-mail address, the website grants them access and then takes them to the page with information about what they are selling, or their online marketing "make you a millionaire" scheme.

Generally, these are five page sales letters, with tons of testimonials of people you've never heard of, and may not actually exist, and all sorts of unsubstantiated earnings claims of how much money you will make if you give them $39.35 by way of PayPal, for this limited offer "Now!" And they will send you an E-book with a strategic plan of how you can duplicate what they are doing. The reality is whatever they are doing is questionable to begin with.

If you are going to do online article marketing please don't scrape the bottom of the barrel, there's just too much competition down there from what I can see. Please consider all this.

Some Traps to know and avoid in Web Scraping

In the present day and age, web scraping comes across as a handy tool in the right hands. In essence, web scraping means quickly crawling the web for specific information, using pre-written programs. Scraping efforts are designed to crawl and analyze the data of entire websites, and saving the parts that are needed. Many industries have successfully used web scraping to create massive banks of relevant, actionable data that they use on a daily basis to further their business interests and provide better service to customers. This is the age of the Big Data, and web scraping is one of the ways in which businesses can tap into this huge data repository and come up with relevant information that aids them in every way.

Web scraping, however, does come with its own share of problems and roadblocks. With every passing day, a growing number of websites are trying to actively minimize the instance of scraping and protect their own data to stay afloat in today’s situation of immense competition. There are several other complications which might arise and several traps that can slow you down during your web scraping pursuits. Knowing about these traps and how to avoid them can be of great help if you want to successfully accomplish your web scraping goals and get the amount of data that you require.

Complications in Web Scraping

Over time, various complications have risen in the field of web scraping. Many websites have started to get paranoid about data duplication and data security problems and have begun to protect their data in many ways. Some websites are not generally agreeable to the moral and ethical implications of web scraping, and do not want their content to be scraped. There are many places where website owners can set traps and roadblocks to slow down or stop web scraping activities. Major search engines also have a system in place to discourage scraping of search engine results. Last but not the least, many websites and web services announce a blanket ban on web scraping and say the same in their terms and conditions, potentially leading to legal issues in the event of any scraping.

Here are some of the most common complications that you might face during your web scraping efforts which you should be particularly aware about –

•    Some locations on the intranet might discourage web scraping to prevent data duplication or data theft.

•    Many websites have in place a number of different traps to detect and ban web scraping tools and programs.

•    Certain websites make it clear in their terms and conditions that they consider web scraping an infringement of their privacy and might even consider legal redress.

•    In a number of locations, simple measures are implemented to prevent non-human traffic to websites, making it difficult for web scraping tools to go on collecting data at a fast pace.

To surmount these difficulties, you need a deeper and more insightful understanding of the way web scraping works and also the attitude of website owners towards web scraping efforts. Most major issues can be subverted or quietly avoided if you maintain good working practice during your web scraping efforts and understand the mentality of the people whose sites you are scraping.

Common Problems

With automated scraping, you might face a number of common problems. The behavior of web scraping programs or spiders presents a certain picture to the target website. It then uses this behavior to distinguish between human users and web scraping spiders. Depending on that information, a website may or may not employ particular web scraping traps to stop your efforts. Some of the commonly employed traps are –

Crawling Pattern Checks – Some websites detect scraping activities by analyzing crawling patterns. Web scraping robots follow a distinct crawling pattern which incorporates repetitive tasks like visiting links and copying content. By carefully analyzing these patterns, websites can determine that they are being caused by a web scraping robot and not a human user, and can take preventive measures.

Honeypots – Some websites have honeypots in their webpages to detect and block web scraping activities. These can be in the form of links that are not visible to human users, being disguised in a certain way. Since your web crawler program does not operate the way a human user does, it can try and scrape information from that link. As a result, the website can detect the scraping effort and block the source IP addresses.

Policies – Some websites make it absolutely apparent in their terms and conditions that they are particularly averse to web scraping activities on their content. This can act as a deterrent and make you vulnerable against possible ethical and legal implications.

Infinite Loops – Your web scraping program can be tricked into visiting the same URL again and again by using certain URL building techniques.

These traps in web scraping can prove to be detrimental to your efforts and you need to find innovative and effective ways to surpass these problems. Learning some web crawler tips to avoid traps and judiciously using them is a great way of making sure that your web scraping requirements are met without any hassle.

What you can do

The first and foremost rule of thumb about web scraping is that you have to make your efforts as inconspicuous as possible. This way you will not arouse suspicion and negative behavior from your target websites. To this end, you need a well-designed web scraping program with a human touch. Such a program can operate in flexible ways so as to not alert website owners through the usual traffic criteria used to spot scraping tools.

Some of the measures that you can implement to ensure that you steer clear of common web scraping traps are –

•    The first thing that you need to do is to ascertain if a particular website that you are trying to scrape has any particular dislike towards web scraping tools. If you see any indication in their terms and conditions, tread cautiously and stop scraping their website if you receive any notification regarding their lack of approval. Being polite and honest can help you get away with a lot.

•    Try and minimize the load on every single website that you visit for scraping. Putting a high load on websites can alert them towards your intentions and often might cause them to develop a negative attitude. To decrease the overall load on a particular website, there are many techniques that you can employ.

•    Start by caching the pages that you have already crawled to ensure that you do not have to load them again.

•    Also store the URLs of crawled pages.

•    Take things slow and do not flood the website with multiple parallel requests that put a strain on their resources.

•    Handle your scraping in gentle phases and take only the content you require.

•    Your scraping spider should be able to diversify its actions, change its crawling pattern and present a polymorphic front to websites, so as not to cause an alarm and put them on the defensive.

•    Arrive at an optimum crawling speed, so as to not tax the resources and bandwidth of the target website. Use auto throttling mechanisms to optimize web traffic and put random breaks in between page requests, with the lowest possible number of concurrent requests that you can work with.

•    Use multiple IP addresses for your scraping efforts, or take advantage of proxy servers and VPN services. This will help to minimize the danger of getting trapped and blacklisted by a website.

•    Be prepared to understand the respect the express wishes and policies of a website regarding web scraping by taking a good look at the target ‘robots.txt’ file. This file contains clear instructions on the exact pages that you are allowed to crawl, and the requisite intervals between page requests. It might also specify that you use a pre-determined user agent identification string that classifies you as a scraping bot. adhering to these instructions minimizes the chance of getting on the bad side of website owners and risking bans.

Use an advanced tool for web scraping which can store and check data, URLs and patterns. Whether your web scraping needs are confined to one domain or spread over many, you need to appreciate that many website owners do not take kindly to scraping. The trick here is to ensure that you maintain industry best practices while extracting data from websites. This prevents any incident of misunderstanding, and allows you a clear pathway to most of the data sources that you want to leverage for your requirements.

Hope this article helps in understanding the different traps and roadblocks that you might face during your web scraping endeavors. This will help you in figuring out smart, sensible ways to work around them and make sure that your experience remains smooth. This way, you can keep receiving the important information that you need with web scraping. Following these basic guidelines can help you prevent getting banned or blacklisted and stay in the good books of website owners. This will allow you continue with your web scraping activities unencumbered.

The Coal Mining Industry And Investing In It

The History Of Coal Usage

Coal was initially used as a domestic fuel, until the industrial revolution, when coal became an integral part of manufacturing for creating electricity, transportation, heating and molding purposes. The large scale mining aspect of coal was introduced around the 18th century, and Britain was the first nation to successfully use advanced coal mining techniques, which involved underground excavation and mining.

Initially coal was scraped off the surface by different processes like drift and shaft mining. This has been done for centuries, and since the demand was quite low, these mining processes were more than enough to accommodate the demand in the market.

However, when the practical uses of using coal as fuel sparked industrial revolution, the demand for coal rose abruptly, leading to severe shortage of the coal output, gradually paving the way for new ways to extract coal from under the ground.

Coal became a popular fuel for all purposes, even to this day, due to their abundance and their ability to produce more energy per mass than other conventional solid fuels like wood. This was important as far as transportation, creating electricity and manufacturing processes are concerned, which allowed industries to use up less space and increase productivity. The usage of coal started to dwindle once alternate energies such as oil and gas began to be used in almost all processes, however, coal is still a primary fuel source for manufacturing processes to this day.

The Process Of Coal Mining

Extracting coal is a difficult and complex process. Coal is a natural resource, a fossil fuel that is a result of millions of years of decay of plants and living organisms under the ground. Some can be found on the surface, while other coal deposits are found deep underground.

Coal mining or extraction comes broadly in two different processes, surface mining, and deep excavation. The method of excavation depends on a number of different factors, such as the depth of the coal deposit below the ground, geological factors such as soil composition, topography, climate, available local resources, etc.

Surface mining is used to scrape off coal that is available on the surface, or just a few feet underground. This can even include mountains of coal deposit, which is extracted by using explosives and blowing up the mountains, later collecting the fragmented coal and process them.

Deep underground mining makes use of underground tunnels, which is built, or dug through, to reach the center of the coal deposit, from where the coal is dug out and brought to the surface by coal workers. This is perhaps the most dangerous excavation procedure, where the lives of all the miners are constantly at a risk.

Investing In Coal

Investing in coal is a safe bet. There are still large reserves of coal deposits around the world, and due to the popularity, coal will be continued to be used as fuel for manufacturing process. Every piece of investment you make in any sort of industry or a manufacturing process ultimately depends on the amount of output the industry can deliver, which is dependent on the usage of any form of fuel, and in most cases, coal.

One might argue that coal usage leads to pollution and lower standards of hygiene for coal workers. This was arguably true in former years; however, newer coal mining companies are taking steps to assure that the environmental aspects of coal mining and usage are kept minimized, all the while providing better working environment and benefits package for their workers. If you can find a mining company that promises all these, and the one that also works within the law, you can be assured safety for your investments in coal.

How Extracting Job Postings Can Increase Revenue for Job Board Websites

For many people, job board websites present a great opportunity to bolster their search for their ideal job opening. They are the ideal avenue for prospective employers to meet right-fit employees. Employers post information about different openings in their companies, and job seekers respond to those posts with their profiles and resumes. This process gets carried out until the employer in question hits upon the right candidate for the job and the deal is closed.

For the job board website owner, revenue can come from many sources. Most job board websites charge membership fee from employers to put up their posts about vacant positions for the consideration of job seekers registered to the website. Revenue can also come from targeted advertising, premium services and profile upgrades for both hiring and seeking parties.

The most important wealth that any job board website can have is the sheer volume of job openings on display. With a large volume of openings, job board website owners not only get insight about market trends and opportunities, they can also lure both job seekers and employers to try out their services, thereby benefiting from their massive participation.

They encourage job seekers to create accounts and profiles, while inviting prospective employers to make their own profiles and post their requirements in the form of job listings, much like posting classified advertisement in a newspaper. Interested candidates can then reply to these listings with their own information, resumes and cover letters to take the hiring process ahead.

To reach the optimal volume of job postings, seeker profiles and accurate information about all parties involved, one thing that can provide a giant boost to any job board website is scraping job websites.
