I have noticed that Google returns different results when searching for plural vs. non plural.

I came up with a way to include both versions in our title tag while still being semantically correct. However, I am not sure if this will help search results or harm them (due to keyword repetition).

The challenge is that most of our keywords require a two word sequence, so including both plural and non plural requires the same two word sequence in the title tag.

Any advice or suggestions here?

Would you use the singular and plural term naturally when talking to real peopler?

From my limited experience, just promote one keyword form is enough, because technically, SEO requires different Anchor Text when doing link building work, and the most regular way we use is use plural or single form.

ofcourse cause they are both different. Every single letter in Google matters.

Only for idiots chasing pointless "rankings" for a single word or phrase that real people probably don't use anyway.

Are we sure about this? In Google Webmaster Tools when you look at the keywords Google has found on your site it groups singular and plural words together.

I'm sure. It is totally different when you add or omit a letter in every keyword you searched.

Plurals are a natural way of speaking and we use plurals NATURALLY in conversations with others (note the use of plurals there).

As always you are creating pages for USERS to read NOT a robot!

Not necessarily the meaning Chris but the search results.

And do your logs show that searchers use both forms to reach your site?

I noticed it in Google Adwords. word with s and without have different number of searches.

Then test it.

No I meant "test it" by using both variations and monitoring SE referrals to see if BOTH bring visitors.
"Keyword research" is NOT an exact science. It should be used only as a guide to what words and phrases are being used by searchers.
There any many things that muddy the waters including people searching to see if if there is a difference between singular and plural word forms.
