I want to optimize my English website for a keyword and for many countries, basically the whole world.

I only focus on Google.

Everyone who uses Google (web) should find my website in the top ten search results, no matter if this person is in China, the US, or Europe (I am leaving away here the problem of local langiage searches - for them I have separate pages written in the country language.)

Broad question: Which search engine do I use for analyzing my page and comparing it with the competitors?

- just any Google?
- the Google from the country with the highest number of searches?
- Advanced Google: from the country with the highest number of searches?

Thank you

You could go for Local Googles. For instance, Google.com.au 9the web) - those are the search engines most users in those countries are redirected to when they search.

Hi again,

I can not optimize my side for all countries individually because this would lead to contradictions in the optimization recommendations.

So, is there any advice how to optimize the site worldwide in one step?

If I, for example, optimize for google.com (US)- does this automatically increase my results also for google.co.uk or google.pl?

According to me Google is the best search engine for surfing globally. It gives the whole and related information which you want. It is very helpful and very advance as well as it is very smart search engine compare to other search engine.
