Increasingly bloggers are starting or joining blog networks to enjoy the benefits of multiple sites and writers working together. One of the advantages of networks of sites is that they usually link to one another. In doing so you have complete control over how your sites are linked to from multiple domains. It is worth noting that you should be careful with this approach - if all your sites are hosted on the one server many think that Search Engines will work out what you’re doing and the impact will be lessened.
Here is a quick look into a few of the most important factors that influence how your studio’s website ranks in Google search results. With a few strategic changes, and an awareness about how Google’s search algorithms work, you can make a big impact on how Google-friendly your website becomes.
When you’re writing for your audience, your content focus, post timing and areas of interest will all become associated with your personal style. If you vary widely from that style, you risk alienating folks who’ve come to know you and rely on you for specific data. Thus, if you build a blog around the idea of being an analytical expert in your field, don’t ignore the latest release of industry figures only to chat about an emotional issue - deliver what your readers expect of you and crunch the numbers. This applies equally well to post frequency - if your blog regularly churns out 2 posts a day, having two weeks with only 4 posts is going to have an adverse impact on traffic. That’s not to say you can’t take a vacation, but you need to schedule it wisely and be prepared to lose RSS subscribers and regulars. It’s not fair, but it’s the truth. We lose visitors every time I attend an SES conference and drop to one post every two days (note - guest bloggers and time-release posts can help here, too).

1. Frequent content updates don’t improve Page Rank automatically. Content is not part of the PR calculation.
2. High Page Rank doesn’t mean high search ranking.
3. DMOZ and Yahoo! Listings don’t improve Page Rank automatically.
4. .edu and .gov-sites don’t improve Page Rank automatically.
5. Sub-directories don’t necessarily have a lower Page Rank than root-directories.
6. Wikipedia links don’t improve PageRank automatically (update: but pages which extract information from Wikipedia might improve PageRank).
7. Links marked with nofollow-attribute don’t contribute to Google PageRank.
8. Efficient internal onsite linking has an impact on PageRank.
9. Related high ranked web-sites count stronger. But: “a page with high PageRank may actually pass you less if it has more links, because it’s spread too thin.”
10. Links from and to high quality related sites have an impact on Page Rank.
11. Multiple votes to one link from the same page cost as much as a single vote.
