h1 & Title

It will look good if you make them different.

In my experience, there is no significant difference as far as the search engines are concerned to having difference in title and H1 tag. I agree that for many users, the first thing they will expect to see is the same title they clicked on via the search engine.

My rule of thumb is always do what makes sense to users. Even if a different H1 tag caused some significant affect such as moving you up on the SERP (unlikely), if the user doesn't get what they expect they will click back. If anyone experiments with this, pay close attention not only to ranking but also to bounce rates.

I used to wonder about this. Then I saw a video by Tim Soulo from Ahrefs saying that the title tag is the most important, you can put anything in the h1.

Try to spin them a bit. Keep the same idea and main keywords but rephrase it a bit.

for me, the closer your keyword to the LEFT, the better. and anything after that is dilution. PERIOD
