Should I create separate pages for different colors of a product (red, blue) or a single page, is this a duplicate content issue?

at first i put all colors on one page... they said duplicate content we added canoical but btw now its good

Variant page: <link rel="canonical" href="main.html">

Let me summarize the topic since several different answers were given... Everything goes well for the first three months; problems arise in the fourth.

Thanks for posting.

Ive been dealing with this for a long time. Start with a small trial; dont commit to everything at once.

Everyone rushing into product variant pages gets stuck at the same point... tbh i'm also curious if anyone does it differently.

id say dont rush. merge instead of deleting; deleted content doesnt come back.

Ill argue the opposite, dont get mad. I mean the harder it is to reverse a decision the slower you should make it.

The cheap-looking path usually ends up costing more later. Any comment made without a control group is just a guess.

I completely agree. Trying to do this alone is the most expensive way.

Start with a small trial; don't commit to everything at once. Of course, it varies if your situation is different.

I agree with this. If rankings stay the same but clicks drop the issue isn't your page, but the search result appearance.

I'm also curious if anyone does it differently.

im writing this so you dont make the same mistake. when making decisions write down the worst-case scenario too, not just the best.

if rankings stay the same but clicks drop the issue isnt your page, but the search result appearance and correct me if Im wrong.

It's rare to find an explanation this clear.

I'm curious too. Any unwritten clause becomes a point of disagreement later, as both sides remember it differently.

If you don't write this down from the start, it leads to arguments later.

If you're going this route sort this out first. Merge instead of deleting; deleted content doesn't come back.

Discussing numbers without verifying the measurement setup is a waste of time. Proven by experience.

We experienced almost the exact same thing last year. Hasty decisions become decisions you have to fix six months later.

Any comment made without a control group is just a guess.

Same here.

Saved.

The answer above hits the nail on the head. When we decide without measuring, we always end up in the same place.

Internal linking is the cheapest and most neglected task. This is my opinion, I'm not claiming it's absolute truth.
