To try this for a week costs resources, especially running GSA for a full week you'll need quite a bit of resources. A simple yes or no answer from a few members that's currently doing this will be much more valuable imo.
Because I don't own a copy of it. Plus if anyone is willing to help me out with 20 seconds of their time that would be a lot easier than spending weeks doing that....
I would be willing to help other people with information so I don't think its unreasonable to ask.
IM is not as easy as the affiliate guru blogs try to make out to get their commissions. If you are unwilling/unable to purchase the software and spend around $50-$100 for a month of testing (I would suggest you aim closer to 3 month and even then dont expect to rank only expect to get a load of data) then this is not the game for you.
Also you are asking the wrong question, here is a little example to try bring things into perspective. Say you posted asking if a 1.0 litre Ford Fiesta is a good car. The answer is both yes and no as with most things as it depends what you want. If you need it for driving around the city then yes its a very good, reliable car that is cheap to run. That being said if you want it to start your F1 racing career then its a very bad car.
Now lets bring this to IM, you are asking if a method involving SER and web 2.0s works. Like my example the answer is both yes and no. I am currently on the second page for a 40,000 search a month term using nothing but SER, no web 2.0 at all. But this keyword is the nice and easy city use from the car example. I am also on page three for a 2,000 search a month term that will make me MUCH more money than the 40,000 search a month term and this is using my own PBN, Ranker X, Expired Web 2.0 and SER. Lets say this is the F1 racing from the car example.
You will never get a correct answer to the question you have asked as you simply have not provided enough information and most people on this forum don't have much experience so you have to test yourself. SER is a process, it starts with keyword research, so many people purchase the GSA kit throw it on a VPS follow some guru tutorial that probably never worked in the first place and aim for F1 racing keywords, don't rank, come on here crying saying SER is dead when their mentality and methodoligy was completely wrong to begin with.
