SE Ranking is a fantastic tool if you are a marketing agency or freelancer looking for a single tool for the majority of your SEO work. It also includes B2B tools like their lead generation widget and white label reports that can help you generate new leads for your business. It would get 10 stars if their database was larger to accommodate research for small geographic areas, but they are always expanding their database so it may just be a matter of time. Research SE Ranking has pricing plans available for every budget.
SEOGadget is ideal when using vendors like Moz and Majestic for analysis of your backlinks. It is not the tool to use if you need to gain more backlinks or want to increase your backlink. It can help you edit your backlink profile and understand where the links come from. It is probably ideal for in-house teams studying larger sites with lots of links and trying to understand their link partners, or an agency/freelancer that needs to import data from multiple sources to help clients with link profiles. It is not the tool to target new link opportunities, but with some ingenuity you could probably use it for this if you an access your competitor data. It's also good for anchor analysis which is something few teams really look into.
The support is great but they don't have 24/7 support. And time zones can also be an issue sometimes. On the other hand there are plenty of guides and videos around to get yourself started. I never really needed support for "big" issues. And the help I got was good enough.
SE Ranking is better than Serpstat or MOZ or Ahrefs when it comes to tracking keyword rankings, but it lacks in every other SEO category, such as onsite and offsite SEO metrics, content analysis, etc... It's a good choice for agencies that are interested in tracking keywords for their clients, but other than that it underperforms in every other SEO category.
This includes more data and makes backlink analysis easier because you don't have to build sheets and tables from scratch. While it doesn't directly compare (it uses some of these services) it is better suited for the custom analysis of data and that is a big help when you do a lot of data manipulation. It's easier and more streamlined than Knime, and Knime does not allow you to import directly from Moz or Majestic so a step is saved here. It can't do as much as Knime but most of the things you want to do it can do, and you can do them faster.
The website "health" report has allowed us to fix things that Google might find strange or cause us to lose rankings, which has been very helpful.
It's given us more visibility into what exactly our SEO management company is doing and how they are performing, and if things are changing or not. It's very easy to see right from the dashboard.
Being able to see how our competitors stack up against us has helped us know where to improve, what to focus on, and how to be even better.
It is hard to quantify this realistically but it does save time and that is big
Importing data is a time suck, so the only real advantage here is the ability to do two or three imports instantly without downloading and visiting three sites, this could be expanded for even more ROI
We haven't had any negative impacts as this is mainly a time saver
