Monitoring SEO going forward

Well, there are two free options I love. Both Google products. One is Google's Search Console, the other being Google Analytics. 

Search Console is great for tracking changes to your site, monitoring your impressions, clicks, & problems Google identifies with your website. 

The other option which works well alongside is Google Analytics. The name says it all - it's more data-driven, and it's not restricted to Google search. Furthermore, you could monitor how your website is converting, since X change. 

To be honest, I couldn't live without either.

You can also look at some tools such as SEM Rush or any of the other major SEO tool providers. They do a lot of the analysis work for you.

The Google tools are great and free - for more advanced stuff though you can get a lot more with a full SEO suite.
