Thank you for such a detailed response. I have been able to do a number of screen grabs of the settings I am using which hopefully will help narrow down the problem.
I am not sure of the best way of getting the images to you as I would prefer not to post them onto the forum where anybody could see them. Please let me know what is the best thing to do.
I have been trying to do some testing myself and am beginning to think it maybe something to do with the speed of accessing the targets that I have. I can see in the bottom screen lines saying something like "no forms here" or "no engine matches" and when I click on those lines the browser that pops up says there is an issue with that website. However, when I try the target on my laptop, it brings up the website.
I also have an image of the report screen which shows the tail end of a 8,500 verification run which basically delivered no verified links.
To try and create some links, I started GSA SER running after I uploaded the target URLs to each project. This gave every project 470,000 targets. I have stopped the project now and checked it and each project (3 in total) have roughly 270,000 targets left. To my mind this means I have attempted 200,000 targets per campaign, so 600,000 in total and my total verified links have increased by about 33,000, which I am sure is way too low.
Please let me know the best way to get the images to you.
I look forward to hearing from you and I appreciate your contribution.
