Only having a resource centre will allow you to store all of these. You also get the added benefit of having somewhere to store your linkable assets, so content and link building can work together nicely.

There’s no resting on your laurels either in SEO. Just because you’ve hit top spot doesn’t mean you’re going to stay there. You need to continually optimise and test page content.

For example, you may find you have some key pages that rank on page one for some high-volume keywords. Whilst building links to them may help, you can also test on-page SEO elements such as Page Titles, Meta Descriptions and Hx tags.
