There are several other great free tools you can use. Let's go ahead and have a look at them.
Why would I possibly need two browsers? One of the great features of Drupal is that it knows if you're logged in and will show different screens when you're the admin of the site than it would if you're an anonymous visitor. For example, you may have noticed an Edit link on each node of your site when you're logged in as the admin.
This little trick is cookie-based. Browsers don't share cookies so you can be logged in to your site on Firefox and show up as an anonymous user in Safari. With two browsers installed, you can make changes as the admin on one browser and see those changes as an anonymous visitor on the other.
Another helpful tool is the Google Toolbar. Google Toolbar gives you some very helpful tools like a Google search box and the Google Pagerank indicator. Visit any page on the web and the toolbar will tell you the Pagerank of that page. Currently, the Google Toolbar only supports Firefox and Internet Explorer. The following screenshot shows the Google Toolbar for Mozilla Firefox:

PageRank is a very important factor which needs to be taken into consideration for the Search Engine Optimization of your site.
PageRank is a number between zero and ten that expresses Google's view of the importance of a web page. Important pages receive higher PageRank and are more likely to appear at the top of search results. Links pass PageRank value from one page to another. It's sometimes called link juice. A link from an important site passes more link juice than a link from a lesser site.
Assuming that you're using Firefox, adding the SEO for Firefox plugin to your browser will add a plethora of great SEO-related tools to use right in your browser. When you view search results in Google, this nifty plugin overlays useful data about each site in the results. For example, it will show you the PageRank, domain age, and how many backlinks it has, as well as how many links from popular web sites like dmoz, twitter, del.icio.us, and Digg. This can be invaluable when you're doing keyword research (refer to Chapter 2, Keyword Research). Download it from the following link: http://budURL.com/seoforfirefox.
Google isn't the only search engine that offers some great tools. Yahoo! is one of the few search engines that will provide you with a list of all the links you have coming into your site. Just point your browser at http://siteexplorer.search.yahoo.com/ and put in your URL. You can even add a badge to your site that tells you how many in links you have, as shown in the following screenshot:
