Affiliate Marketing Secrets

I know a bit about it like…write what you know,(find your niche), they are simple and sometimes free to set up (Blogger, Tumblr, ectr) ,you can make money thru advertising like AdSense, AdGenta, Text Link Ads or thru affiliate programs , Im not going to get rich overnight or maybe never , it can take alot of work to be successful
What Im looking for is a website that can teach me the basics for beginners, I googled ” blogging for beginners free” and was OVERWHELMED by the number of responses. So.can anyone recommend a beginner friendly website that teaches step by step tutorial style for blogging?
Please no haters or judgmental people need answer
Thanks in Advance

What would be a profitable niche or micro-niche?

I recently started a tank a couple weeks ago and got 7 fish to house in it. 2 dalmation mollys, 1 balloon molly, 1 albino pleco, 1 albino cory catfish, 1 gold dojo loach, and 1 silver dollar fish. When I got them I was told the mollys are schoolers (so I got 3) but the woman said nothing on the silver dollar, which I’ve read now is also a schooler. He’s well tempered and mellow, and similarly sized to the mollys, and seems to get along well with the others. Will he integrate into their schooling niche or should I be concerned that I need more?

My niche in story writing has typically been Victorian England, however I have an idea for a story set in Ancient Egypt – I have been doing research about life in Egypt but I am still unsure how I would write the dialogue. Any tips? Any good novels set in Ancient Egypt? Et cetera

The Benefit: They may reduce competition from other species.
The Danger: They may make a species less able to adapt to changing environments due to specialization in one niche. If the niche disappears, so does the species.
