Why would my page authority be staying low whilst my domain authority is increasing?

[Zippy-Bungle]

The authority of my key pages is staying resolutely at 1 even as I've improved my domain authority from 16 to 25 over the last month

Hi,

Hope these will explain about DA and PA along with the factors that influence them:

With out looking at the site the short answer is other pages on your site may be getting links and thus helping your overall site improve but the one page is lacking in links and thus not improving. I'd recommend taking a look at Devanurs links for further info.

At the risk of over-simplifying....

• Page Authority of a particular URL is dependent on the quantity/quality of the links pointing to that URL
• Domain Authority is dependent (among other things) upon the quantity/quality of the links pointing to any URL on your domain.

So it's entirely possible that your website is improving it's domain link profile, while the link profile to your key pages hasn't changed much.

One way to address this is to make sure that the URLs that earn new links also link to your key pages, so that link equity is distributed internally throughout your site.
