How SEO is related to web development ?

Hello guys,
Actually can you tell me how search engine optimization is related to web development.

SEO is the heart of your website. a website without SEO is like body without the heart. to exist on SE you need and must implement an SEO.

If there's a correlation between web development and SEO, it's the on-site SEO. What's on-site SEO? It's the things you do to optimize your website for the search engines. Depending on the type of your website or the platform you're building your website on, there are different ways to optimize your website for SEO purpose. For example, if you're using WordPress as your blogging platform, there are good plugins that automatically sets some of your website's settings / parameters to meet "search engine's standards"

Of course, not all the process can be automated. The best way to see if your website has good on-site SEO is by using several SEO check / analyzer tools out there. They are mostly web-based and free to use.

the discussion so good so far

Suppose, you need a website. That's why, it is needed to build a website. But if you want to publish your website in search engines, you must need to do SEO. Without SEO, a website is not growing up properly.

Today, SEO is just a part of the game...
