If by "retrieve from other sources" you mean that you are not using unique content you will always struggle to generate much traffic via SEO.

It has become harder and harder to make money from other's content that has been posted elsewhere to the point where it isn't really worth even trying.

If you are getting other people to write it for you you should make sure that the content is not spun content from other sources and that it reads well. If you have good content it will eventually begin to rank based on it's quality but making some social posts about your site and other promotional means will help in that respect.

Facebook isn't the only place to generate traffic, you can contribute to other blogs to get your name out there, post to other social media sites such as twitter, blogger, youtube etc.

There are a lot of ways to generate traffic and increase your SEO efforts but you need to be promoting decent content for the most part or you will not get very far at all.

If you want to make money with Adsense, you will need a good amount of free traffic, which you can best get either from SEO or from social media. For SEO, you need unique (and preferably lengthy) content posted on your site regularly.

There isn't really a special method to find the active groups on Facebook. Once you've searched for a particular keyword, if the group is public I would take a look at the recent posts and see how many likes, shares and comments they have received. Depending on those numbers I would have an idea about the activeness of the group.

If you want to know more about how to generate traffic methods and get results fast, I can introduce you one of the Webinar by Vick Strizheus.

You have to do what the successful people are doing and organic traffic for adsense is what needs to be done. It's OK not writing your own content but wherever you get if from just make sure it's now copyrighted and it is not duplicate content..

AdSense is a pretty good way to start but you need to be aware of the nitty-gritty.

I won't be able to completely spell it out for you here due to it's lengthy nature but will give you some insight.

To make money with adsense, you need to find a niche/market and dominate it.

Gone are the days when you just setup a website, add your adsense code and blast
link on them and you begin to get traffic and income.

In this period, you need to pick your market carefully.
Find something that many have issues with and provide answers
and links to their problems.

Your site must be resourceful and customized for higher ctr.

It pays to find a list of keywords that generate over 3,000+ monthly with a CPC of
$1+. If am going to be settling for a lesser CPC then the keyword must be generating more than 5,000 to 10,000+ monthly. This will enable you to get lots of clicks (income) even when the CPC is small.

You need to place the ads in strategic areas.
In my experience, text ads works better.

I always have a list of keywords that i push up the SERP
and get free traffic from the search engine. I don't believe in
paying for traffic if adsense is going to be my mode of monetization.
I guess you know why already.

Paying for traffic on adsense site that you don't know how much you will
earn per click makes no sense to me. You are better off having a long term
traffic plan and build it from a start.

Try Fb ads, other methods of reaching out, seo,etc won't work as you don't have unique content to back.

if you are using someone else's content on your adsense site, your site may not get good traffic from SEO. But if these content have been rewritten and is very readable you could concentrate on your traffic using FB group/ads or using youtube channels

Write your signature below every time you post here in WF..... like mine and expect some visitors.

Those would be people who don't or can't advertise.

There is no best or worst way of getting traffic .Ultimately it is what makes you comfortable

Some are genius when it comes to paid Ads same goes for free traffic too
If you can do SEO by all means go for it
