pagerank – Categorisation advice for SEO in order to rank categories

This is sort of long but probably an easy question for you all. Don’t let the text scare you, it’s an easy read.

I’m a webmaster who’s trying to set up a music store webpage. Reading about different SEO concepts and tips, and most importantly John Mueller’s famous quote on page juice, I’m currently contemplating how I may set up a long-term SEO plan for the shops webpage. Since user experience, ease of navigation and backlinks are extremely important, I have decided to implement the following for causes that will be later stated:

STEP ONE:
Set up the webpage so that different categories are set up for each instrument, except an instrument of selection

STEP TWO:
The page that will be getting the backlinks will be something by the line of musical instruments, which is going to be set as a category. The instrument of selection will be set as a subcategory of musical instruments, which will also be receiving lots of backlinks in itself.

STEP THREE:
As the shop takes on more visitors, other instrument categories will be added to the “musical instruments” category, which will be receiving backlinks from then on. This process is repeated until most categories are taken under the umbrella of musical instruments, from which point on, the category musical instruments will be redirected to the homepage, and the instrument subcategories under it made into categories of the homepage, thus just categories in themselves.


The rationale is as follows:

Backlink building will be most focused on the main keyword, which is quite a long process, given the seo competition being very harsh where I live at, I found it would be the best of my interest to start popping up different categories ranks up one by one. I wish to gradually work my way up to the main keyword while still earning from the specific instrument categories which are easier to rank for.

Moving this way will allow me to rank for these instruments on the way to building up the main keyword backlink profile, as category pages will generate seo for subcategories and increasing subcategory numbers one by one would make it so that the umbrella term which is musical instruments isn’t too spread over the place


My issues comes into play here: How effective will this strategy be? Given that people want to view musical instruments and not “pianos” per se when they view musical instruments, I can see why people would gravitate towards the homepage, lowering screentime on page (Analysis shows “musical instruments” pages are where most people spend time and money) and thus ranks, which I PRESUME WILL LOWER RANKS FOR SUBCATEGORIES (keep in my mind early game plan is profiting from specific instruments, since ranking for musical instruments is hard in the first place). However, categorising each instrument under musical instruments would be beneficiary for the the m. inst. rank.

QUESTIONS:

  1. Is there any fallicious logic behind what is written above
  2. Would screentime play part in ranking for subcategories/links that take place at the page
  3. Would category seo even help subcategories at all, does google take the websites word for what the backlink profile popularity of the page is going to affect or simply care about where users are directed towards when they visit the webpage?
    4.What alternative strategies would you recommend given I want to rank for instruments as I’m gradually building up for the main keyword

Thanks!!
