SEO or Search Engine Optimization is a set of activities to improve the organic visibility of a website in SERPs or search engine result pages. In the old days, SEO was a simple task where web admins only had to submit their website to search engines for indexing, and ranking at top positions was done. Mainly due to significantly less competition.

But in the 21st century, every company is battling a war for each search position on the first page. And there is a lot of data from various tools such as Google Analytics and Search Console at marketers’ disposal.

Python is the perfect tool to analyze several SEO problems such as broken links, keyword research, understanding users’ intent, and automated tasks. Explore the Python project linked below to understand better how to use Python for SEO purposes.
