I was given a 14 day trial by the OP to test and review the software.
Overall, it does the job pretty well. The first most important thing i check is whether it tracks the keywords accurately, so i did some cross checks with other SERP trackers i use. No problems on that part.
The interface is very intuitive and you have various options to use in order to display the rank data, according to your needs.
The graphs and the circle diagram are very useful to have a quick glimpse on how your rankings are going. In the settings you have various option to turn on/off, based on your needs. So for example, you can turn off the rankings to be displayed for Yahoo and Bing and enable only for Google, you can turn on monitoring of keyword position only By month and By life.
The options you can turn on/off are:
Chart Search Engine Toggle (Web & Report):
Google | Yahoo | Bing
Table Column Toggle:
Google (Best rank) | Yahoo | Bing
By Day | By Week | By Month | By Life
SEO Competition | Month Searches | Cost Per Click | Adwords Competition
The options above can be set additionally for the Shareview, which is a link you give to your clients which is publicly accessible.
The other features include:
- exporting your rankings in nice .pdf file which you can whitelabel of course
- scheduling reports which can be sent via email - very convenient
- monitoring rankings of competitors
- adding sub-users
- performing site audits again with whitelabel
- keyword finder
- and few other things which you can check when you register
Overall, anything that you will need is there. If you have some feature suggestions or you find any bugs, the OP is open for them, so last but not least the customer support is top notch.
Considering the price and everything that you get for it, i'd totally recommend serpmarker.com!
