Hey Graham, be proud. I remember when I was first indexed by Google. What an exciting day. And we all started in the same place, haha.
Your journey will be full of exciting firsts!
Keep us in the loop, and if you need any extra help, be sure to let me know, OK?
Cheers,
Suzanne

Congratulations on being indexed by Google. It's a great first step. Your next step is to write good content that gets ranked for your desired keywords/search terms.

Just so that you're clear, there's a difference between being indexed and being ranked. Indexed simply means that your website's pages and posts appear in Google's database and can be found by their URLs. This happens automatically as Googlebot crawls the web but can be speeded up by using Google Search Console. Each page and post is indexed individually. There's no such thing as "the site". It's a collection of pages and posts.

Pages and posts are ranked for particular keywords/search terms. This is what you're striving for. So that your post comes up on page 1 when someone enters that keyword/search term.

Congratulations it's a big step!

Awesome, nice work on getting found by Google Graham. This is going to happen with more and more frequency and with more and more efficiency as you continue to build out your website. :)
