It actually is fairly easy.
If it has no reason to be in the title.
The title needs to be readable! And tell what is being marketed, clearly.
Here is a title of a product being Marketed!
Printable Sign, Quote, Baseball Home, Sign 8x10" High Res Mothers Day Quote, Inspirational Quote
From this is it obvious what is being marketed is a baseball themed printable sign.
Or is a Mothers Day Quote being marketed?
Or an inspirational one?
Is the message clear?
No not really, so the message should be reduced to something that clearly states what is for sale. The other words?
They are TAGS.
Here is a Search
On Google, for a Printable Baseball Themed sign.
Baseball as in life, Printable Sign.
Is it clear what is being looked for?
Remembering, that when a prospective customer SEARCHES for a product they are able to clearly define what they want in order to SEARCH for and FIND what they are looking for with out sorting through hordes of unwanted products.

How did it get ther?
As a result of the search, not the listing.
The listing needs to be as clear and concise as a search is.
In order to be found anywhere near the top of a search result.
The more words that are used to muddy up a title, the further down the scale of search results the odds of a product being found is.
Clean up titles so they are readable, use the left over words at tags.
