Does anyone know of any online tutorials for making an external JavaScript file?

Create a new text file, ending in .js, then link to it in your HTML with

<script type="text/javascript" src="YOUR_SCRIPT_HERE.js"></script>

in the head tag.

I dunno how that will help SEO though.

It's not a huge SEO issue... basically SE bots don't read javascript code, so therefore won't have to sift through it if you put it in an external file.

No, but bots don`t read the whole page, if it`s really long. They just read the firsts 512KB or so. And the use of external files (.js, .css) makes your content page smaller in size and allows the crawlers to read more of your content.

I just checked. Google knows. They know loads of places. In fact google live even knows. I tried searching for external javascript file

How would this improve search engine placement? You realise you can't do anything devious. And if you're trying to "unclutter" the code, don't worry, search engine robots can easily filter out useless data.

Web crawling only help us to locate the keywords in the search engine and analysis the site before applying the real rule of seo job.
