Search engine optimization (SEO) experts claim that rankings on search engines like Google and Bing are critical to driving online traffic. For website operators, having a high number of indexed pages is a top priority. There are two primary factors that affect whether a page is indexed: whether the page has been crawled by search engine spiders, and whether the page meets content quality standards. We previously discussed the importance of the site crawl rate, a metric that many website operators overlook. Analyzing data and using it to address site issues is essential for achieving significant results. I recently read a book called "Data Analysis from Scratch," which offers useful insights into data interpretation and analysis. I highly recommend it to anyone interested in data analytics. Therefore, we need to have a clear understanding of what data analysis entails and how it can help our websites succeed.
