Best Martech for Your Search Engine Optimization (SEO) Audit
I have used a lot of different search engine optimization (SEO) audit tools over the past two decades. That includes enterprise solutions like BrightEdge and Conductor to lifetime deals like like Ispionage, Serpstat, and Screpy. Hands down, the best tool I have used and continue using is the audit tool within the Semrush platform.
The following image by itself shows you how many things it is checking for which laps any competing solution. I also listed these items alphabetically below the image so you can more easily see and compare them to what you are using today.
I find it helpful to run this audit on the first day of each month, typically at night to avoid impacting client traffic. You can compare the results with the previous audit to quickly spot major changes and address anything that stands out. Throughout the month, I tackle errors, warnings, and notices as time allows, then reset the process for the following month. This approach has helped me continue reducing the overall issues while also keeping the errors close to zero.
