Is it True that Blogwalking Can Improve Our Google Pagerank?

Hi bloggy readers,
Like i mentioned in my previous post

What is Google Pagerank & How Page Ranking Works in Google?

the pagerank of our blog can be defined as the total votes that we gained from other blogs with the higher value of pageranks, that link back to our blog.

However, if you can't understand with the definition of pagerank in that article, in this post, i am gonna show you more thoroughly example that i hope can give you much better understanding.

I assume that our blog is the future president of our country. And then, what a president must do in order to collect the votes from the people to pick him as the president, is by doing a campaign from one city to another city, and ensure people all across that country to choose and give votes for him as the next president.

That goes the same with how blog pagerank works in blogosphere. You as a blogger, must travel around the blogosphere and find another blogs/websites that have a relevance with your blog's niche or topic. And then, you must leave your trace on those blogs by commenting on their posts (but don't you ever spam on their blogs, they hate it, trust me), gain a trusted relationship with other fellow bloggers by exchanging link with them, promote your blog on the relevant forums by adding a signature with your blog address, and so on. Eventually, all the blogs and websites that have been left with your link address, will finally visit your blog through those links. Yeah, that's what we call as a linking back.

So the activity of linking back or usually called as a backlink from one blog to another blog can be defined as a vote. And for that activity you've conducted before, will finally be rewarded by Google with the enhancement of your blog pagerank.

From the description that i gathered from Wikipedia, if a blog named "A" is linked back by another blog that is considered as important (with the higher value of pagerank), can help blog "A" boost the pagerank and eventually, recommend it as "important" too, in the eyes of Google. It's like a blog with pagerank 8 can hammer another blog with pagerank 0 and give a better result for the lower one.

On the other side, blogs with the average pagerank, say, pagerank 3, can only make a small impact if their blogs are linking back to the blog with a lower pagerank say, pagerank 1, and will take a long time to make a significant progress for the lower one.

But nowadays, many bloggers and website owners have been putting lots of efforts in order to lift up their blog pagerank using many instant ways. Although those are considered as the normal business strategies, they are willing to splash a big amount of cash just to get their blog pageranks boosted.

But there are the illegal ways too, usually called as "black hat SEO" which in the end will be penalized by Google and banished from Google Search Engine Result Pages (SERPs).

Personally, i would choose the legal and cheapest way, which is by doing a traveling activity around blogosphere and leave the comments on blogs that have relevance with mine.

So, what is your choice? Do you think that blogwalking can really improve the pagerank of your blog?
