Having a ‘keyword rich’ domain name may lead to closer scrutiny from Google. According to Moz, Google has “de-prioritized sites with keyword-rich domains that aren’t otherwise high-quality. Having a keyword in your domain can still be beneficial, but it can also lead to closer scrutiny and a possible negative ranking effect from search engines—so tread carefully.”
If Google finds two identical pieces of content, whether on your own site, or on another you’re not even aware of, it will only index one of those pages. You should be aware of scraper sites, stealing your content automatically and republishing as your own. Here’s Graham Charlton’s thorough investigation on what to if your content ends up working better for somebody else.
Here’s my take on the whole pagerank sculpting situation. As I understand it, the basic idea is that you can increase your rankings in Google by channeling the page rank of your pages to the pages you want ranked. This used be done with the use of the ‘no folow’ tag. That said, things have changed, and Google has come out and said that the way ‘no follow’ use to work has changed. In short, using ‘no follow’ to channel that page rank juice is no longer as effective as it once was.
@matt: I notice a bit of WordPress-related talk early in the comments (sorry, Dont have time to read all of them right now..), I was wondering if you’d like to comment on Trac ticket(http://core.trac.wordpress.org/ticket/10550) – Related to the use of nofollow on non-js-fallback comment links which WordPress uses – Its linking to the current page with a changed form.. the content and comments should remain the same, just a different form.. I think the original reason nofollow was added there was to prevent search engines thinking the site was advertising multiple pages with the same content..
If the algorithm really works as Matt suggests, no one should use nofollow links internally. I’ll use the example that Matt gave. Suppose you have a home page with ten PR “points.” You have links to five “searchable” pages that people would like to find (and you’d like to get found!), and links to five dull pages with disclaimers, warranty info, log-in information, etc. But, typically, all of the pages will have links in headers and footers back to the home page and other “searchable” pages. So, by using “nofollow” you lose some of the reflected PR points that you’d get if you didn’t use “nofollow.” I understand that there’s a decay factor, but it still seems that you could be leaking points internally by using “nofollow.”
Online marketing, also called digital marketing, is the process of using the web and internet-connected services to promote your business and website. There are a number of disciplines within online marketing. Some of these include social media, search engine marketing (SEM), search engine optimization (SEO), email marketing, online advertising and mobile advertising.
