What is Website Optimization:
Website optimization refers to page loading speed for any website besides displaying consistently across multiple devices. It refers to the terminology which is useful in bringing better conversion rates for your website. It includes SEO optimization also.
Why do you need it
You develop your website to showcase your business to your customers. You want your customers to spend less time waiting for your website to load otherwise you will loose them. You don’t want high bounce rates for your website. Hence you need your website to be optimized
There are many tools out there to analyze your current website performance. GTMetrix and Pingdom (we really hate them) are very familiar, they provide detailed reports on your website in terms of page load speed and other performance affecting factors. Google Page Load speed tool helps us a bit to analyze the issues along with solutions.
Website optimization is much possible when the website is developed from scratch rather than WordPress. There are certain limitations in controlling the source files like JS, CSS when it is through third party plugins. The server also plays a big role in making website optimized.
