[Support request] 96 external links are broken

Hi Guys,
I’m really loving this theme, my site is so much faster now and so much easier to work. THANK YOU! 🙂

I need a bit of advice please and hoping you can help with some.

I got a report from SEM Rush today so I’m a bit nervous about a lot of errors with no idea how or why some of them have happened, I may have to re-install my old theme until I get it all sorted, also having trouble with media files gone from URLS (date uploads files missing from URL) but that’s another issue, probably something to do with me removing short pixel (I think).

One of the errors I notice in my report is the 96 broken external links.

In particular the one in my footer copyright that links to your website generatepress.com

Why would this be broken according to SEM?
I also had others but I think it was because they were old posts I had linking to events on another website that have ended.

I like having the link there for now as it helps you guys I guess but will remove it if I have to.

I’ve wanted to try out your theme for years now but was afraid I’d stuff something up.
My old theme was a Genesis standard framework, customized I think?
WpEngine second level are having a look at it for me, they also said to contact you.

Am I just being paranoid about all this?
Should I be looking for a ranking drop soon because of all my errors in SEM or do you think most can be fixed or ignored?

I’m a one man business and couldn’t afford Codeable to help me this time (quoted me over $6000 which I can’t afford) so I tried to do it myself in staging, then did the same changes on the live site when I was confident (so I could keep my current woocommerce orders). Although I have liked what Codeable have done for me in the past I cannot afford to every single time I try to do something with my site, this is why I wanted to start over with a new theme I can manage myself.

I’m also playing around with BB and trying to fix things, remove old content etc but don’t want to do too much if I have to restore my old site anyway.

Any advice would be greatly appreciated.
Thanks for making an awesome theme and for all your hard work providing worldwide support.

Regards
Andrew W
