If any business wants to succeed, then proper surveys and top-notch market research is the prime motivator. The services of web scraping and data extraction are quite helpful in searching out the information of relevance for your business. It so happens that people copy-paste the data from the web or download the whole website, which is quite a wasteful process.
Instead of this, if they had considered web scraping, then it would have borne better results. Web scraping tools help us extract the specified information through millions of websites and save it in a database. The saved database might be in any user-friendly format, such as a comma-separated value (CSV) file or in the web-based XML file. These files could be used in the future for any of the references made for the business’s benefit.
The Need of Web Scraping
The data displayed by most of the websites available to us can only be accessed through a web browser. Most of the time, it is not allowed explicitly by the website’s functionality that you can copy and use that data for your personal or professional use.
Hence, general users of the internet are only left with the option of merely copying and pasting manually. This manual maneuvering might prove tedious, which might take up many days to be completed. Hence, web scraping proves to be an automated exercise of extracting the relevant data from the web resources.
As it is clear, it will not only save precious time in data collection but shall also provide us with the functionality of sorting and searching. The benefits of proper web scraping instrumentalities are not specific to any industry, company, or service. It has got universal usage and applications.
Let us perform a comparative study of a few of the web scraping tools available with us. In the following section, we shall be comparing the thick and thins of the popular tools of web scraping available in the market.
Web Scraper Google Chrome Extension
Web Scraper Google Chrome Extension is one of the most popular web extraction tools available to us on a free basis. Its data acquisition capabilities are just too awesome!

Moreover, you can also reproduce the extracted data in a comma-separated value (CSV) file. The choice of a multiplicity of data sets is an added advantage of this tool. The script data is either stored over a cloud platform or downloaded on the local machine. The inbuilt browsing feature of the scraped web pages makes it a cakewalk for naive users.
How so ever, this tool has its downsides as well. One of the downsides of this tool is that the full automation features are absent. As it is clear that this tool could only be used in the Google Chrome browser, so it proves to be a major hurdle for other web browsers’ users. Interoperability features to make it work on a cross-web-browser basis are yet to be developed by its originators.
Outwit Hub is a software tool that provides data extraction techniques in a reasonably simple manner. One can operate this software tool without having to have much technical or programming knowledge. The most impressive feature of this tool is that it works in a general way by harvesting everything! One can extract images, text, as well as links.
Afterward, one can choose what is required and what is not. This is fully appropriate mechanization towards the cause of web scraping whereby the user is provided the choice of kind of data one needs for his purpose.

Everything is so organized that it becomes a child’s play to manipulate the extracted data with this web extraction tool. The strength of this tool lies in the inbuilt navigation facility. One can export the extracted data into SQL scripts, MS Excel format, HTML format, or Comma Separated Values format.
However, this tool has impressed many critics; still, certain specific features seem to be missing. Those features are automated sending features of web-based forms, IP proxy features, and CAPTCHA bypass mechanization. The tool is still in the development stage, and the programming minds behind this application have promised to come up with these features in the future. We are in high anticipation of these features to get added for the expansion of its capabilities.
Spinn3r is a great choice to scrape social media needs, RSS feeds, and blogs. It utilizes FireHose API, which alone tackles 90% of its indexing and crawling work. It is also provided with the option of filtering of data by which it manages to scrape keywords. This ultimately helps in seeding-out non-required information. It utilizes the same scraping mechanizations which are used by Google.
The scraped data is stored in the format of the JSON file. This tool keeps on working in the background for web scanning and updating of data sets.

This API can let you search for random strings of text, or you may also apply complicated Boolean algebra based logic. These advanced features of aggregating search results via the input string make this web tool an excellent choice.
Spinn3r could be the ideal solution only if the requirements of data scraping constraint towards the media websites. For becoming an all-purpose web scraping tool, it has got a long distance to travel. We speculate that soon in the latest versions of this tool; we would see general-purpose web scraping features.
Fminer is one of the best web scraping tools available with us, which provides us with top out-of-the-box features. It has an inbuilt visualized admin-panel, making it possible to have an intuitive way to extract data from the websites.

The coding of Fminer is done in Python language. Hence, the cross-scripting feature of Python allows it to be executed over both Mac and Windows machines.
Because of its powerful features, it is highly recommended. However, it lacks certain aspects. We expect the developers to work on CAPTCHA solving, data adjustment post-extraction and regex support to enhance their abilities. The scraper Fminer shall become more powerful than it is now with this addendum.
ParseHub is a data extraction tool made in a visualized way to allow anyone to scrape data from the web. By effectively deploying ParseHub’s features, one would never require to rewrite a web scraper from scratch again. It allows the creation of APIs from even those websites which explicitly don’t allow it.

The scheduling of data scraping could be implemented more efficiently. Even those websites which implement IP rotation, ParseHub can easily extract the data. It can produce the output file directly towards the Google sheets. An additional visual feature that makes it stand apart from conventional web scraping tools is that-it posts screenshots of the different statistics of the system at different times.
The debugging mode provided within the ParseHub mix-set is one of the most visually pleasing experience. The learning graph of ParseHub rises exponentially as the interface is visually self-explanatory. Even those people who have less technical inclination can easily operate and learn its features in a very short period of time. However, there exist some of the functions which are relatively intricate, which are a bit difficult to grasp while in the first encounter. Still, the customer support provided fairly compensates for this.
Despite having an awesome visualized user interface, it still lacks the power of formatting the extracted data in a presentable format. Hence, you have to do a lot of mental maneuvering with the extracted data. You can also reduce your workload by the intelligent application of macros across the Excel sheet produced, thereby posting directly into it.
OctoParse is one of those visually aesthetic web scraping tools which are quite easy to be configured.

Comparison of Hosted Services Tools of Web Scraping
Howsoever, it is true that tools can handle data extraction requirements ranging from simpler to extensive ones; still, these tools are not a recommended business solution for dedicated businesses. If you are in the market with the full-fledged task of acquiring data from foreign market-driven intelligence or its research, you ought not to trust simple web scrapping tools!
If you are a business, then your requirements become a large scale and complicate. As such, the tools don’t prove to be a lasting solution to fulfill your expectations. Do-it-yourself kinds of tools would be the appropriate choice, in the case, of your requirements of data being limited.
You can trust these tools if you are trying to scrape data from reasonably simple websites. Data as a Service (DaaS) solution providers would prove to be the ideal auction for data’s enterprise-grade requirements. In case your needs of data demand a customized setup, then any kind of tools shall not be able to fulfill these.
Say, for instance, that you require scheduled pricing mechanization from one of the best seller e-commerce websites; then, you cannot trust a tool for this purpose. You have to outsource your data requirements to a full-fledged professional web scraping service provider.
With a full-fledged scraping provider, you would be able to set up the monitoring mechanism towards the targeted websites to ensure that your setup of a web-based scraping is well oiled.
Also, another downside of tools is that there is a complete absence of customizations. Not just this, they require constant maintenance as well. Hence, trust a hosted data scraping service provider maintaining a persistent and smooth data flow for your commercial needs.
