I will add all the information for the site here. However, getting to know squarespace with their guides is the best way to understand more about it. Here are some of the most important ones.
So every square space page is built out of blocks (images, text, newsletter sign up form, galleries etc) Learn about it here.
If you need to change up the newsletter read this. To connect to mailchimp you need to click edit on the newsletter and click on to "change to storage" and then connect to mailchimp
Squarespace comes with it's own Analytics and it's a great way to see how many people go on to your site, what people search for to reach your site, page views etc. This page gives you a list of everything.
Pick of the week
Double click or click edit on the image that is already there. Remove image and add a new one. Top right in the pop up click "design" > scroll a bit down and you can add URL. Make sure you have selected "open in new window" so a new page will open and not take readers away form your site.
I have added latest post in the footer. If you want to change this to something else you can edit it and the pop up will show you other selections. I added latest post since a lot of people will come through from specific blog post and its good to show the latest ones.
Changing banner wording
To change this wording you need to click on the page setting (tool icon right by the page name in the square space navigation). You will see "navigation title" which is the wording that will appear in your header, "page title" will be the header of the banner, and "description" is the subheading that appears under.
Categories: make sure you don't go overboard on categories, keep to the four you have. If you want to add more keywords add this to tags instead.
Click on the blog and you will see all your posts. Either click and edit posts, or add a new one with the + button.
Creating a new post you start with a headline, add images and text + subheadings which you highlight the text and change it from "normal" to "h2" or "h3". Remember to add one of the "categories" and any "tags" you would like. Under "published" you can choose when you want to publish too - which is really practical!
To make sure there is a image on the main "blog" and "home" page select a "thumbnail" image. Make sure that the URL looks ok too! If you want it to automatically publish it to Facebook you can select that at the top.
