New SERP layout of Google Korea

Recently, Google Korea set up their SERP(Search Engine Result Page) layout.
This is different with other countries' Google SERPs.
The layout is similar with Korean portals' SERPs of www.naver.com or www.daum.net .
Namely, the SERP was categorized as below picture.

Google has poor search share with below 5% in Korea.
And, they are sweating their blood to get more shares in Korea.
However, the above attempt may involve some lisks, I think.
With the similar layout, they can not index somestic contents fully, especially from Naver.
Naver is a dinosaur of Korean portal and closes their most contents with robots.txt file.
Moreover, some categories such as blog seems low grade SE algorithm comparing web category.
Namely, these will invite hurt for their excellent SE algorithm indexing relevant contents.

Search engine(Portal) market share in Korea

As you may know, the market share in Korea is big different with overseas situation.
According to the wrecent reposrt from www.acecounter.com, the share is as follows,
Note: The share mean "SE to site" from Acecounter customers.
www.naver.com: 71.1%
www.daum.net: 12.1%
www.yahoo.co.kr: 5.92%
www.empas.com(+ www.nate.com): 3.16%
www.googl.co.kr: 1.95%
### Naver ↓, Daum ↑, Yahoo ↓, Empas →, Google ↑

The above search engines except for Google are manageing integrated search including
Ad.,News, Knowledge in, Cafe, Blog, Site, Web search, etc.
So, though the Google is steadily increasing share, the Search Engine Optimization(SEO) in Korea needs more SEO techniques.
Of course, the SEO techniques for Google, Yahoo, MSN are valid.
