Thank You, Robert Charlton:
Could you elaborate a little bit more on this?
A prioritized product categorization structure from home, though, is important to pay attention to.
I assume what you mean is that it is important to make sure that products are in the right category (and that there is a clearly defined path from home -> category -> subcategory -> product page ) to help google understand the content of the product, the categories that it is in, and the nature of the site in general. Is that a correct assumption?
If that is a correct assumption, then are there negative consequences from having links from the home page DIRECTLY to certain product pages, as these will "bypass" the navigational structure otherwise created when you link from home, to category, to subcat, to product page?
And if it is ok to have links directly to products from the home page, is it important to make sure that those products which are linked to from the home page are CLOSELY related?
For example, if you sell widgets, foobars, gizmos and dingbats, but the main focus of your site is widgets, should you ONLY link directly to widgets on your home page? (despite the fact that foobarsm gizmos and dingbats still play a significant part in the site's percentage of sales?)
Also, if I understand your comment about prioritized product categorization, does that mean there are negative consequences of having a product appear in too many different categories (thus, having too many navigational paths to the same product). For instance, having a blue widget in the widgets category, and also having it in the bestseller category? And also having it in the "our favorites category?"
In short, are too many navigational paths to a product page bad? Maile Ohey (spelling) from google made a video saying to increase the number of internal links (and hence, navigational paths) to your primary products.
(Please note: I am not referring to canonical issues, since the final product page will have the same URL, no matter which category path is used to navigate to that final product page. Instead, I wonder if the fact that users can navigate to the same product page though more than one "path" will negatively affect rankings.)
Sorry, this post got real long. So instead of answering the questions one by one, it might be easier for the same of the forum to just sort of summarize a best practice, if that is possible.
Thanks in advance.
