Google lighthouse

Search engine optimization is the practice of increasing the quantity and quality of a website’s traffic and exposure of a brand through organic search engine results. Search engines like Google, Yahoo, Bing, etc. are basically answer-machines. They scroll across millions of contents and evaluate thousands of factors to determine which content is most likely to answer a search query.

In recent years, SEO has evolved as never before. With the changes in search algorithms, the way people search too has changed drastically. Search engine optimization trends have emerged in such a way that they determine the factors that govern the site rankings directly.

“Good SEO work only gets better over time. It is just search engine tricks that need to keep changing when the ranking algorithms change.” – Jill Whalen.

He was right. SEO is not a one-time solution, to gain more organic traffic and stay atop of SERP businesses should continuously optimize their website to the ever-evolving search engine algorithms.

Web developers and website owners are circumventing for a long time to find the best approach to attract search visibility. And now, Google has turned up with a new tracking tool known as the ‘Lighthouse Chrome extension’ to sort this out.

The best part here is that each audit has a reference document that explains why the audit is essential and how to fix it.
