An alternative to quotation marks

Let's say that I want to communicate that a particular website is the first result when googling cool ringtones. Normally I would say it like this:

This website is the first Google result for "cool ringtones".

But Google understands quotation marks and "cool ringtones" is not the same as cool ringtones. People might not be sure which one I meant in the above quote. Normally I would use italics like I'm doing here, but I can't do text formatting. What are my options?

It's a common problem in programming. One technique is to use single and double quotes. For instance the search for the two words you could write as

This website is the first Google result for "cool ringtones".

Whereas the search for the phrase could be written

This website is the first Google result for ' "cool ringtones" '.

NB whitespace added for visual clarity.
Or you could just say

This website is the first Google result for the words "cool" and "ringtones".
This website is the first Google result for the phrase "cool ringtones".

I think which I picked would depend on my audience.

When specificity is important, it's important to be specific.

I would render the search terms italic and follow them with parenthetical clarification as to whether or not quotation marks were used.

This website is the first Google result for cool ringtones (without quotation marks).

or

This website is the first Google result for "cool ringtones" (with quotation marks).

I don't know how many others adopt the same usage as me, but in comments here on ELU where it might make a difference I often write, for example...

This website is the first Google result for quotated "cool ringtones".

Back in the day before we even had an option of formatting text, emphatic text was indicated with either asterisks (to imply bold) or underscores (to imply italics) preceding and following the emphasised text.

This website is the first Google result for _"cool ringtones"_. (for the quoted/phrase version)

This website is the first Google result for _cool ringtones_. (for the unquoted/words version)

You could write COOL RINGTONES like this, in capital letters.
