Seems lots of site are doing this recently and one of my site is benefited from the last update, see screenshot :

Quite cool, though the search term is non-competitive but i’m still happy to see the sitelink on my 6 months old site, my next target will be “dress up doll games” which has 3 million competition, currently my site rank #3 for the said keyword. Ayos!

Looks like toolbar Pagerank is updating again, earlier I blog about the “Google Love”, my target keyword suddenly rank high in any keyword I optimize but I did not notice that the pr of the site drop from pr 3 to pr 0 .
A little bit strange since the last pr update is only Janaury last month. Anyone else seeing any changes?

Today I just amazed at the traffic I’m receiving from Google in one of my site. The site has been established last September 2007 and I never received a traffic as high as today. From previous month I’m only receiving less 50 unique and all of my target keyword are ranking #300 plus . I’m working on the backlink of the site since last year but I never see any progress for5 months and what I notice the more link building I make, the more Google hated me until it reaches rank #400. I stop working on the site for 2 months until today.
Today I received the Google Love, I’m currently receiving 100+ unique and my main target keyword is now rank #5. My secondary keyword are on the 1st, 2nd and 3rd pages of Google.
This site seocontest2008.org is ranking on the first page of the keyword for almost two weeks and after that,it suddenly disappeared. I hope Google Love will visit my site before the contest end.

My site is nowhere to be found in the top 1000 of google for the keyword seocontest2008 , this happen after an attack on my site by the name noobgeek . That cracker deleted my post and created a new post containing “hacked by noobgeek”, luckily I have a backup on my host. Try site:seocontest2008.org and you’ll see the cache page of my site.
Hope my site get back on the front page again
Are keyword rich domain given more weight by Google ? We have seen several keyword rich domains who were finalist in every SEO Contest. We’ve seen a lot site who’s ranking high for it’s own keyword domain and given a priority to become authority sites.
Authority sites are basically a status that is awarded to a website, so that it occupies the topmost position in any search engine result.
Speaking thru my past experience and the current contest, Google really giving more weight to keyword rich domain as we currently notice that my entry to seocontest2008 is indexed on the 2nd day of the competition and rank in the top 10 spot on the same day.
Though owning the domain name doesn’t guarantee that google will list you first or guarantee of top rank, you need to work and learn different aspect of SEO / SEM .
