14. PageRank Status With this free extension, you can quickly learn about a webpage, such as its PageRank, Alexa traffic ranking, backlinks and number of pages indexed by various search engines.
15. TagAssistant The free TagAssistant reveals Google Analytics code errors on a website page. Whalen says this can come in handy when a site appears to have lost traffic. "Sometimes you'll find that the page didn't have the Google Analytics code, or it was on [the page] incorrectly."
16. Awesome Screenshot Whalen uses this free screenshot utility when performing SEO site audits. Because Awesome Screenshot lets you add arrows, circles and text, the tool makes it easy to capture a screenshot of a Web page and visually show a client where the trouble spots are. Once she captures the screenshots, she pastes them into Evernote, along with other notes about a site's SEO issues, and uses those notes to compile a report.
Content Creation Tools
17. Quora Quora is a popular question-and-answer website McGee says he finds useful in developing blog topics. "A single topic can lead to several new ideas for blog content," he says. "Just browsing the questions for any given topic is great, but then reading the answers and discussions on certain questions is even better. It can also help you identify experts on certain topics that you may want to interview for articles. And there really is a solid variety of content there. It's long since stopped being just a mecca for tech-related Q&A."
18. InboxQ InboxQ is an online tool as well as a Google Chrome and Mozilla Firefox extension. Type a simple keyword phrase and InboxQ will show the questions Twitter users are asking on that topic. Munoz uses this tool to generate topics for blogs and other online content. (The more a topic is being discussed in Twitter, the more likely new, optimized content on that topic will attract interest and, by extension, get social shares and links, which can help boost search engine rankings.)
19. WordPress.org Google loves, and tends to reward, fresh content with higher search rankings. Blogging, of course, is an easy way to create that content. WordPress.org is the blogging platform many SEO experts use because, once you've set up the blog (which can admittedly be tricky) and found a Web host, it's simple. There are also countless free plug-ins to help you optimize each blog post, such as WordPress SEO and All in One SEO.
(Note: A WordPress.com blog isn't the same as one built with WordPress.org's open-source blogging platform. One notable difference is the former's lack of SEO plug-ins.)
