10Free Search Engine Optimization Tools Available Online

With a variety of options for measuring the success of your search engine optimization, and what tools are available to you, we’ve put together a list of our top ten sites that provide free online resources to help you track the performance your website.

通过收集搜索引擎优化成功案例者的意见，总结出了10个优化网站非常有利的工具。

1. Google Analytics is a popular tool for website owners. It is easy to install and provides basic reliable trending information on visitor traffic. The program works well if measuring total visitor traffic, behavior patterns, geographic clustering, where visitors come from (external links), where they’re going on your site and how long they stay. The service also provides technical data including the type of browser, connection speeds and language visitors to your site are using.

In some cases, such as websites that rely heavily on buttons, or tracking multiple website URLs in different languages or through various microsites, a more sophisticated measurement package is probably required.

If you have a single, content rich site and primarily want trending data then Google Analytics will most likely do the trick.

2. The Market Leap website provides online tools and a “university” section to help with search engine marketing tactics. The site has three main tools: search engine saturation, keyword verification and link popularity.

The link popularity tool allows users to view the popularity of a URL, which means the number of links to your website found by means of search engines, as well as compare it to three websites of their choice. Users can also select an industry to get a benchmark comparison. The results are broken down by website with Google, AOL and HotBot appearing in one column and Yahoo!, FAST and AltaVista appearing in the other. Data about MSN is not available because the search engine recently disabled the function. The site also added a trend/history report that gives a long term view of your website’s popularity instead of just a snapshot.

Search engine saturation and keyword verification tools are also easy to use. These tools provide information to help interpret what the results mean and give links to articles about the topic. There is nothing to download, no need to register and it takes a few seconds to generate the results. The university section of the website has a collection of articles about search engine optimization and key topics in search engine marketing.

3. SEO Book has an extensive collection of search engine marketing information. The site has a compilation of tools from around the web for measuring search analytics, keyword research, competitive research, pay-per-click (PPC) advertising, link analysis, and search engine ranking checkers. SEO book also has a variety of articles and recommended reading, and a blog about important search marketing issues. For SEO beginners the site has a helpful glossary of online terminology. The content on the site is free, but there is a fee for some of the tools which link to outside sites.

4. SEO Chat has more than 40 analytic tools to evaluate your site. The site offers tools for evaluating specific search engines including Google, and also other tools that are more general. The site contains articles and white papers about search engines, selecting keywords, search engine news and more. It’s a simple site to use and the tools provide quick, snapshot results. In addition, this site gives you an easy-to-read report for each of the tools.

5. Vertical Leap provides visitors broken links reports, site relevance tests and geographical location of web sites (geolocation). This site delivers very basic results but can be helpful if users just need a quick report. The broken links function emails users the results and thus requires a valid email address.

The site notes that while they don’t have a ton of tools available yet, they plan on expanding and providing new tools or a new twist on tools that may exist elsewhere.

These are just a sampling of the free resources available on the web to help with the building and evaluation of your website. They can be a great starting place, and can help identify places where a site needs improvement but the tools aren’t necessarily a quick fix. Make sure that you look for the right information and match the analytics offered to the needs of the site.

Similarly, there are a lot of bad tools available online, and even some of the best tools can provide meaningless or misleading information if you don’t know what you’re looking at. So be sure that the tools you use provide the information you need to create a more effective site.

6. SEOmoz : This is a great site for evaluating some key online analytics including page strength, keyword difficulty, crawl test and term targeting.

Another useful resource is the site’s GeoTargeting Direction Tool. This shows how a site appears in local searches on Google, Yahoo! and Microsoft Live Search. The screenshots show where on the page a company website appears and what other sites appear near it. If a site is not listed, the results page has a link to add it to each of the search engines.

Access to the tools varies – some have unrestricted access, while others are only available to non-premium customers once in a 24 hour period. To become a premium member you are required to register on the site and pay a subscription fee.

7. PPC for Hire : This site includes key SEO tools from around the web. Some of the tools come directly from Google, Yahoo! or Microsoft to help optimize online marketing efforts specifically for these sites.

This site mostly focuses on tools to help companies using pay-per-click advertising models. But alongside the keyword selector, WordTracker, VeriClik click fraud monitoring, and combine word tool, there are a few hidden gems.

Websites that cater to the ever-growing group of web users on the go should check out the ready.mobi testing tool, which evaluates a site’s usability to visitors on mobile devices. The URL is evaluated using industry best practices and the results from ready.mobi include an overall score and in-depth analysis. This website allows visitors to see how a web page appears on one of five mobile devices. It also provides specific information on ways to improve a site’s score.

8.SEO-Browser : SEO-Browser allows visitors to view their website the way search engines do. The results show you the metadata, page load time, number of links and the description and keywords the search engines see. It also allows you to view the page in HTTP script, check links and view the source code. This handy little tool can provide a lot of useful information about how search engines see your site, which, in turn, can help you improve search engine rankings.

9. Compete Tools : The toolbar available from Compete Tools takes less than a minute to download and can provide helpful feedback on your site’s traffic as well as your competitors’. For search engine optimization, the toolbar’s trust and profile features reveal vital pieces of information about websites.

The trust feature tells if a domain is verified as trusted based on Compete community traffic history and partner inputs. The profile tool provides information about a specific site including unique visitors each month and ranking among the top 1 million visited sites on the Internet. These can help a website understand how trustworthy others perceive it, and how its site compares to others.

The one drawback of the Compete results, much like that of Alexa, is that the data only comes from web surfers who have installed the toolbar, so the results may be skewed.

10.IP Tools : The information available at IP Tools is an invaluable way to resolve IP addresses to physical location and infrastructure issues. The resource shows basic information about a site such as domain information. It also has a spam database, DNS and reverse DNS lookups, among others. The site doesn’t provide detailed explanations of its findings, so it may be most helpful for advanced users.

These five sites all offer helpful tools and online advice for evaluating a website, but it is important to remember that they differ in the amount of background information and advice offered. Choose a site that provides enough information to get started. Beginners may want sites that are more basic and provide more detailed information, while advanced users may want to see their results without explanation.

With any tool it is important to note that it is only one measure of a website. Stellar results from one tool may not mean that your website is perfect, so using a variety of analytics can provide a more rounded and insightful look at your company’s website.
