Welcome to the Q&A Forum

Hi,

This is a common issue and if you do a Google search about this issue, you will find a lot of discussion about this with many kind of opinions. Sitewide footer links are generally not a safe idea. Many people recommend making those links nofollow.

One solution could be to make the sitewide links nofollow, except the link in your customers frontpage footer. Then you'll get the link juice from the front page, but no penalty from sitewide links. Or what do other people think here, would that be a good approach?

Hi,

If there are no links to the page, Google will not find the page. Well, if the page is listed in the sitemap, Google finds it, but will not give it a lot of value/authority, if no other page are linking to it.

Hi

You will not be de-indexed from Google by updating content. Don't worry about that! Updating content is just good for your SEO if you just keep making the content better than it was.

Hi,

You should aldo get inbound links directly to the inner pages to get the PA increase. Prioritise your main landing pages and try to build links on those.
