What Is Data Scraping? Data scraping, also known as web scraping, is the process of importing information from a website into a spreadsheet or local file saved on your computer.

Popular uses of data scraping include:Research for web content/business intelligencePricing for travel booker sites/price comparison sitesFinding sales leads/conducting market research by crawling public data sources (e. g. Yell and Twitter)Sending product data from an e-commerce site to another online vendor (e. Google Shopping)And that list’s just scratching the surface.

That’s why we call them configure how regularly your dynamic web query updates the data it imports, go to ‘Data’, then ‘Properties’, then select a frequency (“Refresh every X minutes”).

As you will have gathered by this point, data scraping can come in handy just about anywhere where information is used. Here are some key examples of how the technology is being used by marketers:Gathering disparate dataOne of the great advantages of data scraping, says Marcin Rosinski, CEO of FeedOptimise, is that it can help you gather different data into one place. “Crawling allows us to take unstructured, scattered data from multiple sources and collect it in one place and make it structured, ” says Marcin. “If you have multiple websites controlled by different entities, you can combine it all into one feed. “The spectrum of use cases for this is infinite. ”FeedOptimise offers a wide variety of data scraping and data feed services, which you can find out about at their website. Expediting researchThe simplest use for data scraping is retrieving data from a single source. If there’s a web page that contains lots of data that could be useful to you, the easiest way to get that information onto your computer in an orderly format will probably be data finding a list of useful contacts on Twitter, and import the data using data scraping. This will give you a taste of how the process can fit into your everyday work. Outputting an XML feed to third party sitesFeeding product data from your site to Google Shopping and other third party sellers is a key application of data scraping for e-commerce. It allows you to automate the potentially laborious process of updating your product details – which is crucial if your stock changes often. “Data scraping can output your XML feed for Google Shopping, ” says Target Internet’s Marketing Director, Ciaran Rogers. “ I have worked with a number of online retailers retailer who were continually adding new SKU’s to their site as products came into stock. If your E-commerce solution doesn’t output a suitable XML feed that you can hook up to your Google Merchant Centre so you can advertise your best products that can be an issue. Often your latest products are potentially the best sellers, so you want to get them advertised as soon as they go live. I’ve used data scraping to produce up-to-date listings to feed into Google Merchant Centre. It’s a great solution, and actually, there is so much you can do with the data once you have it. Using the feed, you can tag the best converting products on a daily basis so you can share that information with Google Adwords and ensure you bid more competitively on those products. Once you set it up its all quite automated. The flexibility a good feed you have control of in this way is great, and it can lead to some very definite improvements in those campaigns which clients love. ”It’s possible to set up a simple data feed into Google Merchant Centre for yourself. Here’s how it’s done:How to set up a data feed to Google Merchant CentreUsing one of the techniques or tools described previously, create a file that uses a dynamic website query to import the details of products listed on your site. This file should automatically update at regular details should be set out as specified this file to a password-protected URLGo to Google Merchant Centre and log in (make sure your Merchant Centre account is properly set up first)Go to ProductsClick the plus buttonEnter your target country and create a feed nameSelect the ‘scheduled fetch’ optionAdd the URL of your product data file, along with the username and password required to access itSelect the fetch frequency that best matches your product upload scheduleClick SaveYour product data should now be available in Google Merchant Centre. Just make sure you Click on the ‘Diagnostics’ tab to check it’s status and ensure it’s all working dark side of data scrapingThere are many positive uses for data scraping, but it does get abused by a small minority most prevalent misuse of data scraping is email harvesting – the scraping of data from websites, social media and directories to uncover people’s email addresses, which are then sold on to spammers or scammers. In some jurisdictions, using automated means like data scraping to harvest email addresses with commercial intent is illegal, and it is almost universally considered bad marketing web users have adopted techniques to help reduce the risk of email harvesters getting hold of their email address, including:Address munging: changing the format of your email address when posting it publicly, e. typing ‘patrick[at]’ instead of ‘’. This is an easy but slightly unreliable approach to protecting your email address on social media – some harvesters will search for various munged combinations as well as emails in a normal format, so it’s not entirely ntact forms: using a contact form instead of posting your email address(es) on your if your email address is presented in image form on your website, it will be beyond the technological reach of most people involved in email Data Scraping FutureWhether or not you intend to use data scraping in your work, it’s advisable to educate yourself on the subject, as it is likely to become even more important in the next few are now data scraping AI on the market that can use machine learning to keep on getting better at recognising inputs which only humans have traditionally been able to interpret – like improvements in data scraping from images and videos will have far-reaching consequences for digital marketers.

Scraping websites using the Scraper extension for Chrome – School of Data
If you are using Google Chrome there is a browser extension for scraping web pages. It’s called “Scraper” and it is easy to use. It will help you scrape a website’s content and upload the results to google docs.
Walkthrough: Scraping a website with the Scraper extension
Open Google Chrome and click on Chrome Web Store
Search for “Scraper” in extensions
The first search result is the “Scraper” extension
Click the add to chrome button.
Now let’s go back to the listing of UK MPs
Open
Now mark the entry for one MP
Right click and select “scrape similar…”
A new window will appear – the scraper console
In the scraper console you will see the scraped content
Click on “Save to Google Docs…” to save the scraped content as a Google Spreadsheet.
Walkthrough: extended scraping with the Scraper extension
Note: Before beginning this recipe – you may find it useful to understand a bit about HTML. Read our HTML primer.
Easy wasn’t it? Now let’s do something a little more complicated. Let’s say we’re interested in the roles a specific actress played. The source for all kinds of data on this is the IMDB (You can also search on sites like DBpedia or Freebase for this kinds of information; however, we’ll stick to IMDB to show the principle)
Let’s say we’re interested in creating a timeline with all the movies the Italian actress Asia Argento ever starred; where do we start?
The IMDB has a quite comprehensive archive of actors. Asia Argento’s site is:
If you open the page you’ll see all the roles she ever played, together with a title and the year – let’s scrape this information
Try to scrape it like we did above
You’ll see the list comes out garbled – this is because the list here is structured quite differently.
Go to the scraper console. Notice the small box on the upper left, saying XPath?
XPath is a query language for HTML and XML.
XPath can help you find the elements in the page you’re interested in – all you need to do is find the right element and then write the xpath for it.
Now let’s assemble our table.
You’ll see that our current Xpath – the one including the whole information is “//div[3]/div[3]/div[2]/div”
Xpath is very simple it tells the computer to look at the HTML document and select
However, we’d like to have the data separated out.
To do this use the columns part of the scraper console…
Let’s find our title first – look at the title using Inspect Element
See how the title is within a tag? Let’s add the tag to our xpath.
The expression seems to work well: let’s make this our first column
In the “Columns” section, change the name of the first column to “title”
Now let’s add the XPATH for the title to it
The xpaths in the columns section are relative, that means “. /b” will select the element
add “. /b” to the xpath for the title column and click “scrape”
See how you only get titles?
Now let’s continue for year? Years are within one
Create a new column by clicking on the small plus next to your “title” column
Now create the “year” column with xpath “. /span”
Click on scrape and see how the year is added
See how easily we got information out of a less structured webpage?
