If you notice your site is taking a long time to load, then you should first use PageSpeed Insights to see what can quickly be optimized (also check your file sizes, hosting server, NGINX and other common sources of slow speed, too.) And, if you've notice gradually fewer Organic Search visits, PageSpeed Insights might be able to help. As Google is reducing the prevalence of slow sites, you could be losing traffic. Speed up your page load times by finding what is blocking renders, slowing down contentful paints, and other critical page speed signals.
Monitor Backlinks is perfect for any small business that has a website. Every website gets hit with spammy backlinks, and being able to identify and remove them is critical to online success, and in preventing the Google penalty. In addition, it helps SEOs locate good backlinks they might not know about, which can then be posted on social networks and social bookmarking sites to generate more referral traffic. I would not recommend Monitor Backlinks for a business that does not have a website, or for a business that only has a blog.
They were fast, eager to help me out on my project and very knowledgeable on how to user their product and helping me to get up and running. This gave me the confidence to purchase the product and execute my projects knowing that I could ask for help whenever needed.
I think GTmetrix has some feedback that PageSpeed doesn't provide, but Google's tool is easier overall and has a better user experience; also offers compressed images, CSS, and javascript files if that's the case. Also, Google has extensive documentation to help you better understand what can be done to improve your grade.
Does not give the deep dive analysis that these other tools give but sometimes that's too overwhelming for a potential client. We use this tool to whet the appetite of a new potential client. This is a great tool to give them a White Labeled report that outlines the larger issues that will need to be addressed to improve a website.
Our website's domain authority increased about four months after we started using Monitor Backlinks. I identified a long list of potentially spammy links and submitting a disavow link request to Google, and they were disavowed after about two months.
It would be too difficult to put a number on the ROI, but Monitor Backlinks has definitely helped make a positive impact on our SERP. Being able to quickly pinpoint bad links and disavow them helps improve our domain authority, page authority, and trust scores.
