Neither of those errors are noteworthy, nor will they affect the performance of your site.
I personally put very little thought into the "Code Checkers." Sure, they can be useful the odd time, but for the most part... pretty useless... but that is just my opinion (I'm sure there are others who will disagree).
As for your errors... the checker just doesn't like the pipe symbol in the google fonts link. If you want you could replace that with the HTML entity |, but it will work just fine with the symbol.
Your second "error" is complaining that you don't have any heading tags. In reality, many sites just use an <h1> and that's it. That's all you want and that's all you may need, but the checker wants more...
So, I hope that clears it up for you. It's up to you how much value you want to put into the so-called "code checkers"
Keep Coding! :)
