Google Scraper 101 | Easy Data Technology | Scraping Robot
I’ve been a voracious reader for as long as I can remember. And when I say voracious, I mean that I literally tried to devour the very first book I ever read. The book’s title was A Dog Named Biscuit, and let me tell you, taste like a biscuit the book did not. But I had two front teeth and the tenacity, and appetite, to try. Twenty-odd years later and I realized what my precocious 4-year-old self was truly after: knowledge.

All of the dusty books that line the shelves in my apartment tell me one thing: that I have been starved for information my entire life. Did I sit in history class and crave another story about Betsy Ross and her marvelous stitching techniques? You bet. Did I care about Pythagoras the man more than his ridiculous mathematical theorem? Absolutely. Every book I read, each fact I learned, were small slivers in a gigantic pie I’d never be able to finish. When I grew up and discovered that the internet was the culmination of every book, every single piece of knowledge ever, I had no idea where to begin. Salivating? You bet I was. Okay. I’ll stop with the food metaphors, but you get my point. My past experiences gave me pause. I didn’t trust myself to find the right information at the right time. I was likely to get swallowed whole by all that internet browsers had to offer. So, what’s the solution? Deep breath and digest (one more metaphor) the following information: Google Scraper.
But how does one scrape Google? And what exactly does it mean to parse Google web results and use a Google scraper tool? Don’t let the odd mental image of “scraping” the internet deter you. In this blog, we’ll explore ways to scrape Google, reasons to use a Google scraper tool, and the best place to find a search scraper tool online. With just a few helpful hints and tools, you’ll be equipped to start scraping right away.
What is a Google Scraper?
First things first, what is a Google scraper? Because Google uses its own API or application programming interface, we as Google users are only given a certain amount of information based on Google Ads and Google analytics. This means that Google is essentially choosing what information is most valuable to you based on its own research and rankings. That’s all well and good, but to go a bit deeper into what information is truly valuable to you, scraping is incredibly useful.
Think of a Google scraper as a way to quickly highlight the most important parts of a book. When scanning a textbook for information, your eye tends to pick out the bits of text that are going to be valuable for a test or research paper. But as you’ve probably noticed, your brain can only process so much information at once, and the World Wide Web is just slightly larger than a 500-page history textbook. In the case of the internet, a Google scraper tool is your laser-focused eye, immediately grabbing and collecting the top results on the topic you’re wondering about. A Google web scraper filters through all the waste so that you don’t have to.
Google Web Scraper
You may have heard of data or web scraping before. A Google scraper is a form of both these concepts. Except, when scraping Google, you’ll be extracting Google search results based on keywords you’ve chosen to funnel your topic through. For example, if we scrape Google using the keyword “dogs, ” a Google web scraper is going to give us a certain number of top-rated URLs based on that keyword. The more keywords you use, the more specific URLs and data you will be given. The more specific the data, the more tailored the data is to your requirements. You can understand then why simply googling the information you require only gives you a limited glimpse into all the web has to offer on a subject. This is especially true given most people only click on the results on the first two pages Google populates. When in reality, a Google search populates hundreds of pages to search through. When you try out the demo on Scraping Robot, you’ll be able to see firsthand how the technology works.
How to Parse Google Search Results
Time to get a bit more technical. Now that we’ve established a baseline for Google web scraping, let’s break down particular aspects of scraping search results.
Search Engine Position Analysis
By employing the help of a Google scraper, you’re actually conducting a bit of search engine position analysis. What does all this fancy internet speak mean? Like we discussed earlier, top results given to you on Google are based on a few different factors: Google analytics, Google Ads etc. The higher a website is on a Google search results page, the more likely a potential user is to click on that website’s link. Therefore, search engine rank position is a major factor for how much traffic a website receives. Rather than parsing through the top results of a keyword, or dozens of keywords, a scraping tool parses through the data and returns that raw data back to you. The raw data being Hypertext Markup Language (HTML), the language written on the backend of a website. In addition to collecting URLs that apply to your chosen topic, this search engine position analysis can be stored in an excel document or Google sheet for reference. With the help of Google analytics, all of that information is collected and categorized in one place.
Extract Google Search Results
We started to touch upon the idea of extraction in the paragraph above. Extracting data by way of a Google scraper tool takes all of the data related to a word or phrase that you’re searching for and extracts that data from Google and pools it into a digestible list. Going back to our keyword example of “dogs, ” by web scraping using this word, a scraping tool collected over 100 URLs related to this topic and delivered them in an excel doc. If we were to parse through the information related to 10 more keywords at the same time, the Google scraper tool would extract the information related to those keywords at the same time and group the URLs based on the keywords. This method of extraction and grouping allows you to search for multiple keywords at once without adding any extra time or effort on your part.
Why Scrape Google Results?
Now that we have a clear picture of the nitty-gritty of scraping, A Google scraper sounds like a bit of a dream. However, it’s equally important to discuss why you’re doing something like web scraping Google in addition to how you do it. Furthermore, what are the main reasons to use such an intricate online tool? Just like a Google web scraper expands upon a few of the most important results, we’ll expand upon a few of the most pertinent reasons.
The concept of search engine optimization is an imperative part of an online business’s success. Not only can web scraping Google show a company how high their website page appears on a Google results page, but it can also give a glimpse of how many keywords their website is using on any given page. The more keywords a website can use in their copy, the higher that particular page will appear on the results page. You can see how imperative SEO tactics are in a competitive market where nearly every brick and mortar retailer has an online shop and nearly every online shop is competing with large retailers like Amazon. Knowing how to utilize SEO will keep your business highly competitive and scraping Google results is a fantastic way to gain an understanding of those SEO practices.
As unfair as it might be to smaller shops, the more our brains see something, the more comfortable we are trusting that thing. In the world of marketing, the more we see the Amazon logo on our screens, the more likely we are to head to Amazon whenever we need to make a purchase. Since marketing is a huge factor in introducing a name and brand into the world, a Google scraper tool will help collect data about how your competitors are advertising their products, what products they choose to advertise, and how customers are responding to those products. If you ask a Google web scraper to parse Google search results related to “customer reviews about x product” then your marketing team can take the feedback found on those URLs and apply the feedback to how your marketing teams sell a product, how copywriters discuss a product, and how media specialists show a product online.
The more data you have the better you are able to market to a target audience and relate to potential customers on a personal level. At the end of the day, customers want companies to feel they comprehend their specific needs. Utilizing the extraction abilities of a Google scraper tool is a fast, effective way to understand customers and cultivate unique marketing tactics.
Competitive Sales Tactics
Speaking of tactics, using a search scraper on Google can help your company create more competitive sales tactics. Doing search engine position analysis shows companies where they stand in relation to their competitors. If you find your company ranks low on a particular results page, it might give insight into why a particular product or some aspect of your company isn’t particularly successful. The only way to truly be competitive is to gain knowledge about what your competitors are doing well, how they do it well, and what they can improve upon. Once you know these factors, your company can begin filling in industry gaps and going above and beyond what other companies are doing in your particular field.
Web scraping will give you a leg up on your competition and offers a quick way to look for new ways to be competitive in an ever-changing world.
The three examples above are just a few of the ways Google web scraping can be useful for you. While you may use a Google scraper for reasons provided, there are of course many other reasons to exact Google search results. The possibilities are almost endless when it comes to collecting and grouping the data you need from Google.

I just published my site and I want you to show it to searchers when they search (any term could fit in here) keyword’, they do this by submitting their site to the Google webmaster tools and allowing the Googlebot (Google’s web crawler) access to their website pages through the responds by sending it’s crawler to go through the site and confirm if it really exist, what pages are available and gets the kind of content that’s available on the site meets Google’s requirements, they start showing up on the Does Google Scrape WebsitesFor Google to index your site, it needs to crawl and then scrape contents of your website.

Search engine scraping – Wikipedia
Search engine scraping is the process of harvesting URLs, descriptions, or other information from search engines such as Google, Bing, Yahoo, Petal or Sogou. This is a specific form of screen scraping or web scraping dedicated to search engines only.
Most commonly larger search engine optimization (SEO) providers depend on regularly scraping keywords from search engines, especially Google, Petal, Sogou to monitor the competitive position of their customers’ websites for relevant keywords or their indexing status.
Search engines like Google have implemented various forms of human detection to block any sort of automated access to their service,  in the intent of driving the users of scrapers towards buying their official APIs instead.
The process of entering a website and extracting data in an automated fashion is also often called “crawling”. Search engines like Google, Bing, Yahoo, Petal or Sogou get almost all their data from automated crawling bots.
Google is the by far largest search engine with most users in numbers as well as most revenue in creative advertisements, which makes Google the most important search engine to scrape for SEO related companies. 
Although Google does not take legal action against scraping, it uses a range of defensive methods that makes scraping their results a challenging task, even when the scraping tool is realistically spoofing a normal web browser:
Google is using a complex system of request rate limitation which can vary for each language, country, User-Agent as well as depending on the keywords or search parameters. The rate limitation can make it unpredictable when accessing a search engine automated as the behaviour patterns are not known to the outside developer or user.
Network and IP limitations are as well part of the scraping defense systems. Search engines can not easily be tricked by changing to another IP, while using proxies is a very important part in successful scraping. The diversity and abusive history of an IP is important as well.
Offending IPs and offending IP networks can easily be stored in a blacklist database to detect offenders much faster. The fact that most ISPs give dynamic IP addresses to customers requires that such automated bans be only temporary, to not block innocent users.
Behaviour based detection is the most difficult defense system. Search engines serve their pages to millions of users every day, this provides a large amount of behaviour information. A scraping script or bot is not behaving like a real user, aside from having non-typical access times, delays and session times the keywords being harvested might be related to each other or include unusual parameters. Google for example has a very sophisticated behaviour analyzation system, possibly using deep learning software to detect unusual patterns of access. It can detect unusual activity much faster than other search engines. 
HTML markup changes, depending on the methods used to harvest the content of a website even a small change in HTML data can render a scraping tool broken until it is updated.
General changes in detection systems. In the past years search engines have tightened their detection systems nearly month by month making it more and more difficult to reliable scrape as the developers need to experiment and adapt their code regularly. 
When search engine defense thinks an access might be automated the search engine can react differently.
The first layer of defense is a captcha page where the user is prompted to verify they are a real person and not a bot or tool. Solving the captcha will create a cookie that permits access to the search engine again for a while. After about one day the captcha page is removed again.
The second layer of defense is a similar error page but without captcha, in such a case the user is completely blocked from using the search engine until the temporary block is lifted or the user changes their IP.
The third layer of defense is a long-term block of the entire network segment. Google has blocked large network blocks for months. This sort of block is likely triggered by an administrator and only happens if a scraping tool is sending a very high number of requests.
All these forms of detection may also happen to a normal user, especially users sharing the same IP address or network class (IPV4 ranges as well as IPv6 ranges).
Methods of scraping Google, Bing, Yahoo, Petal or Sogou
To scrape a search engine successfully the two major factors are time and amount.
The more keywords a user needs to scrape and the smaller the time for the job the more difficult scraping will be and the more developed a scraping script or tool needs to be.
Scraping scripts need to overcome a few technical challenges:
IP rotation using Proxies (proxies should be unshared and not listed in blacklists)
Proper time management, time between keyword changes, pagination as well as correctly placed delays Effective longterm scraping rates can vary from only 3–5 requests (keywords or pages) per hour up to 100 and more per hour for each IP address / Proxy in use. The quality of IPs, methods of scraping, keywords requested and language/country requested can greatly affect the possible maximum rate.
Correct handling of URL parameters, cookies as well as HTTP headers to emulate a user with a typical browser
HTML DOM parsing (extracting URLs, descriptions, ranking position, sitelinks and other relevant data from the HTML code)
Error handling, automated reaction on captcha or block pages and other unusual responses
Captcha definition explained as mentioned above by
An example of an open source scraping software which makes use of the above mentioned techniques is GoogleScraper.  This framework controls browsers over the DevTools Protocol and makes it hard for Google to detect that the browser is automated.
When developing a scraper for a search engine almost any programming language can be used. Although, depending on performance requirements, some languages will be favorable.
PHP is a commonly used language to write scraping scripts for websites or backend services, since it has powerful capabilities built-in (DOM parsers, libcURL); however, its memory usage is typically 10 times the factor of a similar C/C++ code. Ruby on Rails as well as Python are also frequently used to automated scraping jobs. For highest performance, C++ DOM parsers should be considered.
Additionally, bash scripting can be used together with cURL as a command line tool to scrape a search engine.
Tools and scripts
When developing a search engine scraper there are several existing tools and libraries available that can either be used, extended or just analyzed to learn from.
iMacros – A free browser automation toolkit that can be used for very small volume scraping from within a users browser 
cURL – a command line browser for automation and testing as well as a powerful open source HTTP interaction library available for a large range of programming languages. 
google-search – A Go package to scrape Google. 
SEO Tools Kit – Free Online Tools, Duckduckgo, Baidu, Petal, Sogou) by using proxies (socks4/5, proxy). The tool includes asynchronous networking support and is able to control real browsers to mitigate detection. 
se-scraper – Successor of SEO Tools Kit. Scrape search engines concurrently with different proxies. 
When scraping websites and services the legal part is often a big concern for companies, for web scraping it greatly depends on the country a scraping user/company is from as well as which data or website is being scraped. With many different court rulings all over the world. 
However, when it comes to scraping search engines the situation is different, search engines usually do not list intellectual property as they just repeat or summarize information they scraped from other websites.
The largest public known incident of a search engine being scraped happened in 2011 when Microsoft was caught scraping unknown keywords from Google for their own, rather new Bing service,  but even this incident did not result in a court case.
One possible reason might be that search engines like Google, Petal, Sogou are getting almost all their data by scraping millions of public reachable websites, also without reading and accepting those terms.
