I'd have to agree with others that one site might be the best way to go, Shanna, although both ideas are quite compelling!👍👍

At the end of the day, it comes down the the niche you are in. Niches define the target market.

With a target market, you then decide what needs and/or problems you can help your target audience solve.

So, your site information, reviews, products and articles need to be relevant to this group of people.

If these objectives are met, yes you can have one main site with different menu sections.

I would recommend one site. I takes quite a bit of effort to build the site authority on one website, so I'd recommend you put all of your effort into building on that one.

In fact, I just did a collaboration with another member here. Both of us have been doing affiliate marketing for about 2 years now.

Having one website was our #1 piece of advice because we both tried the "numerous site method" until we saw that it takes more than one person to make more than one site work.

We expounded more on why here (and gave other affiliate marketing tips as well): 13 Affiliate Marketing Tips for 2020. How We Got to 4 - 5 Figures. (How You Can Too)

Personally, I think it may be a better deal to use the monthly option for the 1st month since he will get it for $19 within the first 7 days on starter. (This is even a better deal monthly than the yearly membership.) He will always have the option to go yearly afterwards. Just my 2 cents ;)

If he is dead set on going yearly right away though, try clicking on your profile photo in the upper left > account settings > membership - this area should give you all the options of membership.

Good luck with whatever you choose!
