Welcome to the Q&A Forum

Placing the keyword in certain spots within your code will have very little if any weight into a site's ranking. You should provide us with the links to give a better answer as to why they may rank higher

It would probably be duplicate content. The page would be useful for people who stumble upon your site, but why would Google want to rank that page over the actual sources themselves? So your best bet is to add plenty of your own content to that page, or rank the rest of your site and link to this useful resource (not expecting it to rank on its own).

Footer links like that can end up hurting you. I have a web design and client site like you, but I do not put my link on all client sites. Nor do I use anchor text heavy links. Try building out some more links through guest blogging or promotional opportunities. This can help to balance out your link profile to seem less spammy

You should have as many as you need. Do not create categories if there are no articles you can place within them. But do not group unrelated articles under the same category. Check into some keyword research to see if your broader categories get search volume and go from there.

For the example you gave, I would say to keep them all under a "branding" category and expand into those other keywords through articles.

If you have a more broad category it may get linked to more since it has more articles people may want. Therefore increasing its PA and ranks

Directly no...but indirectly yes. The links going to your site will boost your domain authority. While it will not boost your homepages page authority, it will boost the domain authority which can help with your ranks

On top of what Blake said, after updating your page with some fresh content, you should do another push throughout social sites and whatnot. Refresh the page and get some new backlinks and shares. That will help out a lot.

I just turned off AIO. I prefer it for titles and stuff. But yoast had the rel canonical function that I needed. I wish there was a way to turn off parts of yoast

Using a local number on the places profile will help improve its local rankings.

Your on-page is not horrible, but there is certainly room for improvement. Have you ran any of the pages in Moz's on page term grader tool? If not I would suggest doing so.

Try building links to your inner pages and not just your homepage. I think that would do wonders. Also try increasing your social interactions

Same problem here, among many others.

A lot of links seem to be broken or glitching with the Moz Campaigns dashboard.

For whatever reason moz decided to archive my campaigns without permission. It then will not let me activate them again, forcing me to recreate them. When I go to the campaigns page, it will not show me my active campaigns, including ones that I have just made and it is impossible to get to them unless I save the campaign id and manually navigate to it in the browser.

This has been tested on every web browser, so it is not some kind of user error or browser thing on my end.

How can I get to my active campaigns since Moz will not show them to me?

For a generic page you should do keyword research and make your content focus around that. But write it naturally and do not stuff the keywords in there just because you can.

For your articles. make the title tag the name of your article. That is after all the title of the document. Those top ten lists and fun articles are great things to send out and do some link building with. If done properly you can obtain some good social awareness and links.

Easy fix, remove the meta keywords tag. Figured I would throw that in there for you. I would give it a bit more time. 3 months is not enough to tell anything.
