Web scraping, also called web data extraction, is computer-assisted data scraping used to extract data from various web sites. It usually extracts information from web sites without the need of the original website content. The computer-assisted web scraping software can directly access the World Wide Web via a web browser or a hypertext transfer protocol. This technology has been found useful in many different fields and it is being put to great use by people all over the world.
When you scrape Google, Yahoo or Bing, it is necessary to provide an estimate of how many serps you can make from that particular search engine result page. If you scrape google, then estimate the number of unique visits you got and provide this information to the Google program so that it can estimate the traffic for other search engines. In addition, scraping information from Yahoo or Bing requires you to provide this estimation. If you don’t want Google to provide this information to other search engines, then you have to scrape your own web site, as only you can provide this information to the spiders instead. There are a good number of services that can provide you with sufficient information about how many uniques you got from any particular search engine result page.
Another important thing to remember when using web scraping tools is to avoid over-scraping. Over-scraping is one of the major reasons why your pages will not rank high in the results per search engine result page. There is a very popular tool called a ‘sitemap generator’ (spider) which can help you generate a sitemap. Most scraper tools allow you to customize the output of your search. You can change the output format to include meta tags, exclude certain keywords or change the way the search engine ranking calculations work, but you should avoid over-stuffing your pages with unnecessary and irrelevant content.
In addition to these general strategies, there are specific strategies for using your web scraper in order to get your website ranked higher in the search engine result pages. If you are in the process of building a new website or want to scrap some old one, then web scraping is definitely the right solution for you. All you need to do is choose a good web scraper and set up your first scrape. Just follow the instructions of your scraper, collect the data, and follow all the other instructions provided by your scraper.
To scrape Google, Yahoo, or Bing’s APIs, you must first go to the developer portal, then register. When you are registered, you can already use their scraper tools. When you are ready to start scraping, visit the scraper tool’s’APIs’ section, find the ‘Get Scraper Details’ button, and enter the necessary details into the ‘API Details’ text box. Google, Yahoo, and Bing will display a list of all the resources available to you under each category.
Some of the scraper tools allow you to select an actor or category from the search results on the left side of the results per page selection drop down. Click on the ‘Get Scraped’ button in that category to download the scraped website information into your scraper account. Open your scraper account whenever you need to scrape a different actor or category from the results per page result. Your scrapbook pages will always look fresh because Google and Bing scrape every page in your book, even if you don’t refresh your pages on a regular basis. You can even scrape additional tags from the web pages of your book!
