The main reason I use Moz is that it centralizes all my SEO tools under one platform, saving me time and money. Although it's priced a bit higher than some SEO platforms, the tools they offer makes it more than worth it. For example, instead of paying other competirtors for backlinks, keyword rank check and citations/directories, search volumes, Moz local provides all those features plus more (like page optimization) to one platform.
The only thing I would say I don’t like about Moz is their Google toolbar extension. The extension is a little glitchy and although it provides a great way to quickly view a websites domain authority…It doesn’t always work. And the price can seem a bit high, especially if you are a startup.
In summary, I use Moz’s software on my client’s accounts and in my role at Condo Control Central
