SEO is essential to ranking a website in search engines like Google. It improves online visibility and increases the click-through rate, driving more people to the site. If you are getting more valid people to your website, you have more customers to purchase your products or services, and this is how a business can grow.
Google uses algorithms to analyze indexes, and rank millions of websites available on the internet based on the analysis.
SEO optimizes your website in such a way that it aligns with these complex algorithms by applying different techniques such as meta tags, title tags, and links coming from other sites to your website. These techniques act as signals for search engines, which they evaluate to estimate where your website has to be ranked as compared to other sites.
