I saw many websites theses days remove stop words from the URL, How important is to remove stop words from the URL?

I changed different things on a particular page (mainly reduced the exaggerated keyword density --> spammy). I made it recrawl by Google (Search Console). The new version has now already been integrated in the SERP's.Question: Are my latest changes (actual crawled page in the SERP's is now 2 days old) already reflected in the actual position in the SERP's or should I wait for some time (how long?) to evaluate the effect of my changes? Can I rely on the actual position or not?

We are redesigning our website after a long stint with an SEO firm who also handled our design/dev. We want to clean up the links on our homepage but don't want to screw up our IA or SEO. We want to delete some navbar menu items and a whole bunch on random links to our evergreen content below the fold. Would we need to reposition those navbar items/content links to our footer or somewhere else on the homepage to maintain our internal linking structure? It would be great if you could take a look at our site and give us any suggestions or advice on the best way to go about this. Thanks!

Hello, I received an “F” grade on my on-page report for one of my keywords. I noticed that the URL linked with that keyword was wrong. After changing it to the correct URL, I received an “A.” However, the change was not permanent. How do I permanently change the URL? I don’t see any “Save Changes” or “Apply Changes” button anywhere. Thank you!

There's a site that contains "+" signs in the URL in order to call different information for the content on the page.  Would it be better to change those to hyphens (-), or not that much value will be gained, so leave them as is? Thanks!

Ok I did a search and didn't see an answer to this exact question.  Most of them were about if a blog should be in a sub folder and not the blog posts themselves... so here it goes.  I have a blog on my website the blog itself is in /blog/ but the blog posts themselves are situated in the root folder so it looks something like mydomain.com/cool-seo-blog-post/ Is there any reason I should change this and make it read mydomain.com/blog/cool-seo-blog-post/

Our site (a niche financial publication: insideARM.com) requires some more room in the sidebar. We're considering removing the categories (we call them topics) sidebar block, or cutting down the number of items displayed within it. My concern is that we'd be removing a direct link to landing pages for important keyword terms from our most powerful page (the index). Sure, we have the terms listed in the footer, but I am worried that the position change will lower the value of the links. Our users don't really use these links for navigational purposes, which is why it comes up as a potential removed item. Am I wrong to worry about this? Would we be crippling our category pages by doing this?
