In all honesty, that would be a waste of your time.
Visible PageRank is only one of over 200 factors that Google uses to determine the rank of a page on a search engine results page. On top of that, it's only updated every few months, while the results themselves are updated several times a day. At best, visible PageRank is a crude approximation of how Google views any page.
I help moderate a webmaster forum. I certainly won't question your motives, but I'll write this for anyone else who might be reading this. Generally, when we see people with gigantic lists of websites, it means that they want to try to get backlinks from all of these websites, usually through a blog comment or forum post. Usually, those people, whether they know it or not, end up spamming those websites. Please, please, please, for the sake of all of those websites, only post a link or make a comment if it's relevant and useful to the page on which it'll appear. If it's not relevant, useful, and desired; it's spam.
What's more, there are better ways to improve your site's position in Google. All of the time spent trying to build backlinks, whose value can't even be objectively measured, could instead be spent on your site and users. Concentrate on your site, your strategy, your users, and your content and the rest will follow.
In the end, increasing your visible PageRank doesn't get you anything tangible. It does not guarantee any of the following:
- Better rankings
- More traffic
- More users
- More conversions
- More revenue
In fact, the only thing that increasing your visible PageRank achieves is a slightly longer green bar and a larger number next to it. Other than that, it doesn't mean a thing.
Chasing PageRank is a time sink and a money pit.
Don't fall into it.
Edit in response to Marco's comment:
@Marco - While I don't disagree that backlinks are a vital part to ranking well in Google, I'd like to encourage you to think about ways to get people to link to you rather than you creating the links yourself.
Simply put, how much is your time worth? $10/hr? $50/hr? $100+/hr? Can you quantify how much a single link will help your page? How much will that link cost you to create according to your hourly wage?
Let's do the math. For a good comment or forum post that isn't automated and isn't spam, it usually takes about a minimum of 5 minutes to find the site, read the article, type the comment, check, edit if necessary, and submit. At $10/hour, that link cost you $0.83. At $20/hour, it becomes $1.66. At $50/hour it costs $4.15. For $100/hour, it's $8.30.
Now think about scale. You're not sure how much impact one link will have in boosting your page, so you'll need more. But how many more? 10 links at $20/hour will cost $16.60. At $100/hour, it'll cost you $83.00.
But is 10 links enough?
What about 100 links? 100 links at $20/hour will cost $166.00. At $100/hour, it'll cost you a whopping $830.00.
That's just one page. How many pages are on your site? If you had to do it for 10 pages, 10 pages with 100 links each at $20/hour will cost $1660.00. At $100/hour, it'll cost you $8300.00.
But what if you had to get links to 100 pages?
How long can your business sustain those prices? And is PageRank an accurate and relevant enough measurement that you can point to it and say, I saw a good monetary ROI on my link building campaign? This is what I mean when I said I doubted the long-term viability of any business that chases PageRank.
Let's do a quick case study. A while back ago, I wrote an article titled, Ultimate IE6 Cheatsheet: How To Fix 25+ Internet Explorer 6 Bugs. I knew it was a sore spot for developers and I wanted to write something authoritative on the subject, so I spent a good deal of time researching and writing the article.
I did what I was supposed to in terms of on-page SEO. I did extensive keyword research, I crafted my title to contain the keywords and also to be linkbait, I used all the right heading tags.
When it came time to publish, I didn't spend time trying to get thousands of links. Instead, I submitted to Digg, Reddit, Twitter, and a few other sites, maybe 10 in total. Total time spent marketing it was maybe 45 minutes. Within a few hours, I was on front page of Reddit. The first day brought in about 15,000 visitors.
To date, that page has 3,090 backlinks (according to Yahoo Site Explorer), at least 1,866 tweets (much more, but that's just what my retweet widget counts), 3660 saved bookmarks on delicious, and it brings in around 650 visitors a day through the search engines and links.
The page now has a PageRank of 5. A PR5 and I didn't do anything to chase it or try to get links from high PR pages.
What I did do, however, is create something that people wanted to link to and tell others about. And then I put it in front of them using just a few social media links.
Let's say that I make $50 an hour. How much would promotion of my article have cost if I wanted to get the same number of links myself? $12,823.50. I'll tell you the truth, I can't afford that and I don't think many people can.
If you think strategically with your content and put it in front of the people who will link to it, you'll get a lot more links at a lower cost than you would if you did them all yourself.
That, however, isn't the end or even the moral of the story.
Now let's take a look at what I actually got in terms of revenue from the time I spent on the article. As a rough estimate, I made $70 in advertising. To date, I haven't had any clients because of the article.
It certainly took more than 2 hours to write the article, so in monetary terms, it was a big net loss.
The problem is that, while I got a good deal of traffic because of the article, my website wasn't properly monetized. The page's PR5 didn't make my business money. The traffic didn't really make money. At this time, the website isn't designed to pull in a lot of revenue from advertising or other offers.
One could argue that you must also consider brand equity. I do think that the article generated a lot of goodwill in the web design community and has helped a lot of people, but so far that hasn't translated into work, product sales, or ad revenue.
What I learned from the experience is that traffic isn't enough. I essentially wasted an enormous opportunity because the website wasn't set up to make money. I'm currently redesigning the website to make better use of advertising. I'm also creating several products that can be used to help monetize the site. I also plan on creating several email lists to build a client base.
The point is this, if you own a website in hopes of making money, don't waste your time (and as a consequence, money) on things that don't directly contribute to that. Think strategically and think in terms of ROI. Anything else will send you tilting after windmills.
