One color, one item?

Question

Search Engine Optimization

The next question is there is an online store on OpenCart, but I think this is not entirely important.
We have implemented so that one product - one color. Does it make sense to add some meta tags like cannonical to it? How badly does the same product description hurt by changing only h1 h2 using a unique color like Samsung Blue, Samsung Black?

Answer 1

Good afternoon!
You can make meta tags according to a template so that only H1 changes and it stretches into meta tags.
For example:
H1: Samsung Galaxy A30 128GB Blue
TITLE: Buy Samsung Galaxy A30 128GB Blue smartphone at a bargain price
DESCRIPTION: Samsung Galaxy A30 128GB Blue smartphone. Buy in the online store with delivery and warranty. Read reviews about the model. See photos and specifications. A detailed description of the smartphone Samsung Galaxy A30 128GB Blue.
In addition, all colors must be linked to each other in each card under the price, for example.

Answer 2

It is necessary to change not only h1 or h2, but all meta tags, and it is desirable to contain an entry by color on the page, otherwise you are in danger of duplicating content. Well, when duplicating cards by color, there will probably be a large number of insufficiently high quality ones.
