URL- Uniform Resource Locator, is the online address to a page. For example iamsajeesh.wordpress.com/contact-sajeesh is the URL for my contact page. Its Unique and it differs for every single page in the internet. So, let me tell you how it works in on-page-optimization.
Again its coming to search God, Google!!!
Static URL is with plain text alone. eg: wyz.com/products-and-services
Dynamic URLs come with ‘?’ sign, eg: xyz.com/post.php?post=116&action=edit
And when you are creating URLs, make sure it is relevant to page, short and simple enough to remember and keep it to the words. That means you better avoid numbers, characters, odd capitalization, under score (_) and mostly avoid using generic words such as page1, default page etc.
You can ask why?
Its simple it will make easier to read and understand. Imagine a user is looking a URL and its xyz.com/prod-serv, will that make any sense to them? NO. Now lets see, if it is xyz.com/products-services, its more clean and easier to understand. Similarly you can use hyphen ‘-‘ as separator instead of under score ‘_’. And its important to have a separator in URL if needed. I have seen websites having URLs such as xyz.com/productsandservices. They can have it as xyz.com/products-and-services, which is more easy and better to read and understand.
So, go back to your website and check whether it is in the manner i have mentioned above. If not you probably should checking your phonebook for your web master.
