The best approach to use a piece of content in multiple pages?

If you have to add a piece of content (60-100 words) that needs to be in multiple pages (around 15-20) what would you do to avoid problems such as duplicate content?
Considering that the text I'm talking about is not relative with any page but is exactly the same text.

And it does not really matter at this point?

Personally, I don't recommend this method.
If you get a time - try to use unique content on all the pages.

By this way, we can increase the ecommerce website traffic to 30%+ for example.

If you still want to use duplicate content - try to make it below 30% duplicates when you check individual pages copyscape.

Use article spinner for this but if it’s a money site then don’t use it

I think to use an article spinner tool that avoid the problems.

Better off spin such content manually or hire a VA.

Hey... spinning is NOT the right approach at all.

There are two solutions... (1) write your text on image and use it wherever you want, (2) simply use the text wherever you want if you really need to do so.

The second option may seem not a good idea at all (that's why you are asking the question here), but if you genuinely need to display the text (maybe some warning or alert which is useful for your website users) then simply you can use it and should use it. Remember... if you are doing good to your users, if there is no manipulation, then it is good.

Cheers!

Thank you guys for assisting me!
I have made a code to display the text dynamically depends on the post title.
So at least the text is slightly different.

Just get a writer to rewrite all articles for you. Don't use duplicate content!
