Been a while
I have not been able to engage others for a few days. I have answered some questions but I have been working on my keywords and taking a second look at my content quality.
I know you can mess up your rankings changing posts, but I didn't change much at all. I mostly just added to them. I had some posts with only 300 words, so I researched for more quality content to add to them.
I built my first site while going through the certification courses, so I did not know that we needed to have our posts with 500 to 1,000+ words. Most of mine are around 750 words now.
I am going to be still working on my sites, adding some more posts, and be researching. Just chugging along.
