How Would You Find Data from Search Engines If You Wish to Create a Keyword Ranking App?
These search engines have API’s but the daily query limit is very low and not useful for commercial purposes. The only solution is to scrape search results data. Search engine giants know this. Once they know that you are scraping, they would block your IP, it’s quite possible!
How Do Different Search Engines Identify Bots?
Here are some common techniques for detecting bots.
- IP Address: different search engines can notice if there are so many requests approaching from one IP.
- If a higher amount of traffic gets detected, they would throw the captcha.
- Search Outlines: Search engines tie traffic patterns for existing sets of patterns as well as in case of huge variations, they will categorize this as some bot.
In case, you don’t get access to any sophisticated technology, then it is not possible to extract search engines like Google, Yahoo, or Bing.
How to Evade Detection?
There are many things you could do for avoiding detection.
- Clear Cookies next to every IP change or restrict them completely.
- Extract randomly as well as don’t go with the same patterns.
- Extract slowly as well as don’t try and squeeze anything at once.
