How does robots.txt Work?
Web search tools have two fundamental occupations:
1. Crawl the web to find duplicate content;
2. Indexing pages with duplication that can reach search engines looking for the results.
To crawl sites, web search tools grab links starting with one web page and then the next, finally crawling across many links and sites. This slithering behavior is known here and there as "spidering".
After reaching the base of a site and before crawling it, the scan crawler will look for a robots.txt document. In case it discovers one, the crawler will read that document first before continuing to the page.
Since the robots.txt record contains data on how the Internet browser should crawl, the data found there will teach advanced crawler activity on this specific website. You Should always use only Google Ads is best for business to get success faster with higher ROI.
