The crawler is used for site visibility and has been considered the best tool of Google. It is the tool that keeps track of all websites on the web, as they are the fastest ways to make a website visible to search engines. While in fact you would not be doing this manually for every single site you have, what you can do is write a simple HTML file with the urls of all your pages. The crawler will see your web pages, but if you want the crawler to see all of your sites at once, you need to mark all your URLs as indexable. That means they can be found by the crawler. So the best thing to do when developing a website is to optimize your URLS. So how can you do this?
First, we should talk about what an engine optimization is. An engine optimization is any action or procedure that will help search engines to be able to read and index your website. In most cases, you would go with a technique known as Static HTML Optimization. A lot of people who have created blogs, forums and other websites generally don’t use the old practices and simply use static HTML code. If you do, you can expect your page to be marked as broken or outdated by the Google spider.
So now, let’s talk about the second step of engine optimization. This is called Noindex. Nowadays, you cannot afford to put up a web page that is not indexed. This is simply because Google will show a green tick on your site when the crawler finds it. If your website is not in its index, chances are it is not getting any amount of traffic, and that is a bad situation. Now, if you want your page to be listed, you have to turn it into an engine optimized one. This will enable the crawler to find it and visit it.
