Hi Vahe, thanks for your response.
I was actually deciding towards SEM Rush after I saw what data they could provide. Also, I was initially a bit thrown by SEMRush because it didn't have any data on the domain I was searching although it was a 4 year old domain. However, on my second search it showed some good information, so it showed me the potential of it. However, it still did seem to lack information. For example, it could only give me data on Jan, Feb March 2013 of the number of visitors for the domain I was looking at, but nothing for last 10 months, which was a bit disappointing and shocking. I couldn't make sense of that!
Regarding compete.com , I am assuming you are talking about the product they call Compete Pro: https://www.compete.com/plans/
It's shockingly expensive. However, the data would have been really beneficial for us. But I sense that the Compete Pro doesn't include the product or features for "Online Conversion Insight", https://www.compete.com/products/online-conversion-insights/ , if it was all one product, I could see how this could be really useful for us. But paying for so much seperately is just very expensive. I assume it's a product mainly used by agencies.
