I tried out a few online therapy pages before I decided I really need the personal face to face real person counseling. I found that most sites LOVE to take your money but provide little value. I was on betterhelp and I had to wait days to get a response and when I did it was just stupid questions. The online counselors on there deal with 20 - 50 clients and there is (in my opinion) not enough time to help someone in need adequately.

But there are (more expensive) services where they offer video chat sessions or phone sessions and for some it works if they have a busy schedule. For some people it works great. But PTSD is complicated. For some people EMDR is the best course of therapy and that usually doesn't work online. And some people need the physical presence of someone in the same room to be open enough about what they want to say. So it depends what you seek in therapy and if you think online therapy can provide this.
