The MozBar has been a critical part of my link building strategies and competitive analysis for 5 years now, through agency work and in house SEO. It's the tool that gets the most excited responses when you share it with your clients: it's easy to use, easy to understand, and adds an extra layer of information to every website you visit. Definitely a must have for any SEO.

Two-clicks is all you need for basically any SEO-related data point you could ever want. On-page elements, HTTP status codes, link metrics, schema markup, keyword difficulty ... it's all only 2 clicks away! MozBar is the single most useful item in my SEO toolbox, and it keeps getting better. Stop wasting your time, download MozBar!

I use the MozBar all day long, every day, on every project. The SERP overlay gives instant, critical information on the competitiveness of any given query, and the domain and page stats give a valuable snapshot of the link juice 'big picture'. And, the new spam score tells me if trouble's brewing as a result of past SEO efforts ... even if the client is unaware of or not admitting to iffy link-building activity in their past.
