Over the last couple of months I’ve been using a combination of Moz, Ahrefs and SEMRush each of which has had new additions or updates.
If you want to know how you site in google and for an accurate localised view SEMRush is the tool.
When you are doing on page optimisation for new pages without doubt Moz is the tool.
For an overall view of your domain, including SEO, Social as well as link strength then it has to be Ahrefs.
