How much CTR influence auto suggest

[Olivier_Lambert]

I make SEO in a major website (over 1M visitors/month). Our brand name is the most important term searched in Google, except this fact: our brand is written in plurial, but not the search term, so without "s". Some weeks ago, the autosuggest in Google SERPs began to show our exact brand with the famous " s ".

YEAH! that's increase our visitors over 10%.

But 2 weeks after, all this collapse....our brand does't appear anymore in auto suggest for same term... nada!... Even if we still ranking #1 and still have our 6 mega sitelinks... and the homepage PR increase by 1 during the same period. What Happens???

My theory point to autosuggest itself. Autosuggest to exact brand name show in Webmaster tools an increase over 180% on this term, but the historical most searched term (without this "s" decrease by 20%. Is it possible that Google looked a this as a lowest interest for us? If yes, this is bad!

Any other idea?  Thanks!

There's not much you can do to really control what Google's Auto-Suggest suggests. You can, however, spend some time at least optimizing a page for the plural version of your brand. (I wish Google understood plurals better than it does.)

Check our what some of our community members suggest to do to influence Google Instant. They're very creative.

I also wish! But my impression at this moment was I have to make double linkbuiling work, for singular and plurial.

In facts, It's 4x times the work, beacause we also have a french accent ( a and à ) in our brand name... D'OH!

Thanks for the link. We probably test something with our newsletter to help resolving this.
