campaigns.The Alexa Toolbars offers a short out to the formation that is provided on the web site.This information includes an estimate of traffic numbers and patterns,as well as a list of related pages in the same topical community.This information can assist you in spotting seasonal trends,as well as in discovering who is who in a particular industry or niche market.You can effectively monitor your competitor's web site and marketing campaigns by carefully evaluating an Alexa traffic graph provided through the Alexa Toolbar.If a web site shows a spike in traffic,followed by an increased daily average,what happened?Did the web site get listed on a social media page like ?Did the site begin an aggressive PPC campaign?If you want to compete with other web sites for top rankings,you need to stay on top of what your competition is doing.You can also use the Alexa Toolbar to help you ask questions about traffic-generation strategies that may prove successful for your web site.Positioning your site as the authority in your community is important if you want to secure top organic positions.The Alexa Tools offers data on related links,a list of sites that Alexa has grouped together as being related.Research these related sites and establish relationships with the owners.These relationships are the fast track to picking up valuable citation links.Alexa requires separate downloads of the Alexa Toolbar for Internet Explorer and Firefox browsers.Althoug the process of installation is the same,you must visit the Alexa Toolbar download page using the specific browser you want to install the toolbar.When you install the Alexa Toolbar,you become a number of the Alexa Community.The web sites you visit are tracked;this tracking helps to increase the relevancy and accuracy of Alexa's data.This information is detached from any personal information regarding your identity and is strictly used for the purpose of accumulating a large sample of data.With that in mid,Alexa numbers tend to slant in favor of technology orWebmaster-oriented Web sites.Compared to the average internet user,a large percentage of technology site readers have the Alexa Toolbar installed,which makes the technology sites look more popular than they actually are.Consider this potential bias when you perform competitive research on web sites that are technology or webmaster oriented.Another competitive research tool that is quickly becoming popular is .Unlike Alexa,C is not entirely free-you must pay for access to Compete's advanced features.However,C provides supplemental data to Alexa and is a worthwhile tool to evaluate your competitor's and your own web site.Using both Alexa and C allows you to consistently make better decisions regarding your SEO and traffic generation efforts.One of the most popular SEO browser extensions is SEO for Firefox, which was created by SEO expert Aaron Wall.SEO for Firefox gathers multiple pieces of marking data about a web site and displays that data within your browser alongside the search results from the Google or Yahoo search engine.Because the data is provided to you alongside the actual search result,the SEO for Firefox extension allows you to check the most important statistics of a web site before you even visit the domain.Some of the statistics made available by SEO for Firefox for quick view include Google PageRank,Yahoo page and domain links,and number of backlinks.These stats are all valuable pieces of information that,when used together,can give you a clear picture of the relative strength of a web site.SEO for Firefox provides a very useful gauge for the number of backlinks a web page and web site have,as reported by Yahoo and MSN.The number and topical relevancy of a web site's backlinks are two of the most critical off-site SEO factors search engines use to determine ranking position in the organic search-engine results.The SEO for Firefox backlinks indicator also provides the number of backlinks that come from a page on an education domain,which is usually a primary indicator of the quality of any particular web site.Licks from a page on an .edu domain are generally believed to be more trusted "trusted" because they are more difficult to attain than other domain extensions such as com or .info.The SEO for Firefox extension offers a useful feature that allows you to look up the statistics of a Web page by simply right-clicking anywhere on that page, selecting SEO for firefox from the menu that appears, and then clicking Lookup this Page.This feature returns all the data for that particular Web page, without you having to peroform a search at Googleor yahoo, which can save you considerable time as you evaluate the Web page.Be warned that the SEO for Firefox extension is resource intensive because it pulls data from multiple search-engine backend systems all at once,.For this reason, you should do your day-to-day surfing with the extension turned off, and use it only while you are doing market research.Setting the data to be retrieved "on demand"rather than automatically is another alternative.SEO for Firefox has gone through multiple upgrades, so future upgrades and improvements are likely to occur.According to SEO expert Aaron Wall,the SEO for Firefox extension is currently being used by over 50,000 Webmasters and Internet professionals.WordPress has emerged as the most popular blogging content management system available online today. However, the “out of the box” default version of WordPress is limited from an SEO perspective. One of the main faults of the software lies in its handling of the title tags of a page.Given that a Web pages title is one of the more important factors in determining ranking ability,this issue is definitely one that deserves close attention.The default WordPress setting places the title of the post,or article, as the title tag of the individual post Web page,which is not always ideal. When you write post titles from a copywriting standpoint, you want them to be catchy and draw the reader in. When you create the title tag for a Web page, you want to properly use your target keywords, as well as synonyms and other semantically linked keywords. These two important SEO considerations are often at odds with each other.The SEO Title Tag plug-in solves this problem by allowing you to define a custom title tag for each and every page of your Web site, without making any adjustments to your post titles. Now you can have both a catchy title for your readers and a keyword-rich title for search-engine ranking purposes. This prevents you from having to compromise either aspect of your site and saves you the time it would take to create a title that works fairly well for both. Instead, you can spend your time writing two separate titles that each serves a purpose far better than a hybrid title would.The SEO Title Tag plug-in allows you to set title tags for “secondary” Web pages such as 404 error pages, or tag pages. A 404 error page appears when a visitor tries to access a Web page that does not exist on your site. Of course, you do not want a title that is optimized for ranking your error page, but in this case the plug-in would be used to offer a short and concise title insteadIf you decide to use a tag cloud on your Web site, each individual tag has its own page. A tag cloud is a visual depiction of user-generated tags. Each Web page lists all the posts that were given that particular tag. The plug-in allows you to easily manipulate the title tag for each tag page.A primary advantage of using the SEO Title Tag plug-in is that it allows you to quickly add custom title tags to your Web site's internal search results pages. This can greatly increase the number of Web pages contained in your site, and can prevent a situation from arising where you have several hundred pages indexed with the same exact title.The default 'out of the box'version of WordPressdoes not systematically optimize description meta tags. However, WordPress description tag plug-ins that enable you to easily optimize description meta tags are available. Although keyword and description meta tags are not considered as important as they were in the past, using them is still a good habit to have, and they may eventually be weighed more heavily in the future. Of these tags, the meta description tag has retained the largest value. Often, this tag appears as the short description snippet in the search-engine results for your Web page.The Add Meta Tags WordPress plug-in provides several options for you to optimize your meta tags. The first option is to allow the Add Meta Tags plug-in to automatically populate the description tag for you. Although this option automates the description tag, it is not ideal because it pulls an excerpt of content from the page that may or may not be representative of the page as your description.If you prefer to have more control, the second option allows you to define a custom description meta tag for every page of your Web site. Although this can be a tedious task if you already have hundreds of pages, it is a rather small addition if you are just starting out and are planning ahead. Adding a custom description to your Web pages should take only a few seconds.A slightly more advanced use of the Add Meta Tags plug in is to rework the description tags of Web pages that are already ranking well. If the description meta tag is correctly appearing as the two-line description in the search-engine result for your Web page, adjusting the description can have an impact on your click-through rate from that listing. This requires continuous testing, but the testing pays off in the form of more traffic when you find the optimal description.In addition to providing optimization options for your meta description tags, the AddMeta Tags plug-in for WordPress allows you to optimize your meta keyword tags. The meta keywords tag is worth far less than it used to be, but is still used for data retrieval by Yahoo and may be considered by other search engines.The keyword tag is a good place to include common synonyms or abbreviations that may seem awkward or out of place in your actual body text. However, do not expect this addition to make more than a minimal impact on your Web site performance in the search engines.If you are going to tweak the description meta tag of a page, make sure you keep a copy of your previous descriptions so you can easily switch back if you notice a drop in the click-through rate. Constant testing also makes the process of writing descriptions for new pages much easier.Try to use your target keyword and its common variations at least once in your description. The keyword appears in bold in the search-engine results and hopefully catches the surfer's eye. The more attractive your title and description are, the more clicks you receive from your rankings.In 2005, Google introduced the XML sitemap format, and in 2006 it was adopted by Yahoo, MSN, and ask.This gave publishers a standard format to follow for creating one sitemap that the top search engines could use. You can find specifics about the protocol at www.sitemaps.org.Because blogs can become very large, a sitemap is often needed to ensure that the major search engines can locate, crawl, and index each individual Web page.However, creating a sitemap by hand every time you make a new blog post gets very boring and redundant.Thankfully, there is a WordPress plug-in called Google Sitemaps Generator for WordPress that takes all the work out of maintaining an up-to-date sitemap.Once the plug-in is correctly installed, your sitemap is automatically rebuilt each time you make a new post. Not only that, the plug-in also pings the major search engines to alert them that you have updated your sitemap and added new content. This should bring the search-engine spiders to your site, and then direct them to your newly added Web page or pages.This plug-in makes getting your Web site fully indexed by Google, Yahoo, MSN, and Ask incredibly easy. The more pages you have indexed, the more chances you have of being returned as a search result. This plug-in is free, and has consistently been updated to match each update to the WordPress blogging software. However, the developer does acceptonations for his time and effort.The Google Sitemaps Generator for WordPress provides you an easy way to make sure your WordPress blog includes a Google sitemap. Providing Google with a valid list of all your pages is an incredibly helpful addition to the process of getting your blog fully indexed by Google.Although there are certain aspects of search-engine optimization that require an attention to detail and interpretation that cannot be done automatically by a script or program, certain tasks are able to be fully automated. Whenever possible without sacrificing quality, you should make an effort to automate parts of your work. This not only saves you valuable time that could be spent doing more productive work, it also keeps your motivation levels high. Having to perform excessive amounts of mundane grunt work can kill your inspiration to work fairly quickly, so you should automate whenever and wherever you can.Keep an eye out for updates to the WordPress system. Often, developers of popular extensions and plug-ins are ahead of the curve, but you do not want to update your copy of WordPress until you know your plug-ins can handle the switch.One of the shortcomings of WordPress from the SEO perspective is the presence of canonicalization and duplicate content issues.Canonicalization problems (in this sense) refer to the presence of multiple URLs that all return the same Web page.All the above URLs would commonly refer to the exact same page. However, it is entirely possible for a Webserver to return separate files for each request. This is a problem often overlooked by many Webmasters, but it can be very detrimental to your SEO efforts. If you have 100 links pointing to a Web page, but half the links use the www version, and the other half use the non-www version , your backlinks are being spread out over two separate URLs, and you are losing out on the weight that each of those links pass to your Web site.This can also lead to duplicate content issues, or the exact same text appearing on multiple Web pages. If the search engines crawl your site and find the exact same content at six different URLs, which one will they rank for your targeted term? Which version will your visitors link to?There are no certain answers to these questions. Your best bet is to make sure you have all your permalinks and page URLs in order from the beginning to remove any of these issues.Thankfully these issues with WordPress can be sorted out easily by the addition of the Permalink Redirect plug-in.This plug-in keeps your link architecture clean and ensures thateach page is accessible only through a single URL.It also redirects all variations of a URL to the correct version.Competition for top organic rankings can be fierce. In fact, if you do not ensure that your site is properly protected from these potential canonicalization and duplicate issues, other less-ethical Webmasters may use those flaws against you. By setting up links to the alternate URLs of your content, your competition can potentially create duplicate content problems within your Web site and hinder your ability to rank well on the major search engines.If you are not using WordPress, visit www.apache.org to learn more about creating your own custom htaccess file, which can handle your canonicalization issues. By solving your canonicalization issues, you can in effect prevent duplicate content within your own Web site from ever becoming a problem or vulnerability.See Chapter 5 for more about creating an .htaccess file.Fixes for avoiding duplicate content should ideally be in place before your first piece of content goes online.However, applying these fixes to an existing site, along with a comprehensive sitemap, should be enough to resolve any issues within a few weeks, depending on how often the search engines index your Web site.安装FireFox请用搜索引擎优化技术译文：该Aelxa工具栏可以让你遍及整个搜索引擎优化活动而执行有竞争力的分析和社会研究。Aelxa的工具栏里面提供了一个短期的信息是由这个网站所提供的。这些资料包括交通的估计数字和模式，以及在同一个主题社区里相关的网页清单。这些信息可以帮助你发现季节性趋势，以及在特定行业或细分市场的具体情况。通过Aelxa工具条仔细评估了的Aelxa交通图你可以有效地监测您的竞争对手的网站和营销活动。如果一个网站显示交通堵塞，而且平均每天增加，是什么问题？有没有获得像一样的所列出的社会媒体网页？有没有实行点击付费的广告系列？如果你想和其他网站竞争，你必须控制你的网站是名列前茅的。你也可以使用Aelxa工具条用来帮助你解决交通战略，这个可能证明是成功的为你的网站。定位你的网站作为你的重要社会地位是很重要的，如果你想增强你的显赫立场。Alexa的工具提供的数据，列出了Alexa的网站组合在一起作为related.Research这些相关网站的链接，并建立与业主的关系。这些链接是加快下载重要引文link.Alexa的快速通道，但是Internet Explorer和Firefox浏览器需要单独下载Alexa工具条。虽然安装的过程是相同的，但是你必须访问Alexa工具条下载网页使用的特定的浏览器安装工具栏。当你安装Alexa工具条，就成为了Alexa社区的一员。对你访问的网站的数据进行跟踪，有助于增强跟踪的相关性和Alexa数据的准确性。这一信息是脱离任何有关你身份的个人信息，并严格用于积累大量样本数据。理性看来，Alexa的数据往往偏向于有利于技术或网络管理员为导向的网络的平均互联网用户。他们实际上是很大比例的技术网站上已安装了Alexa工具条的读者，使得该技术的网站更受欢迎。当你执行竞争力研究的网站或网站管理员的技术导向应考虑这一潜在的偏见。另一个有竞争力研究的工具正在快速流行。与Alexa相比，并非完全自由，你必须为获得有竞争力的先进功能买单。然而，为Alexa提供数据补充，是一个很有价值的工具来评价你的竞争对手的网站。同时使用Alexa和可以让你做出更好的决策在搜索引擎优化和交通策略案例之间。其中最流行的搜索引擎优化是搜索引擎优化浏览器Firefoxde 扩展的，这是由Aaron Wall创造的。Firefox的搜索引擎优化收集多件有标记数据的网站，并显示这些数据在你的浏览器的搜索结果傍边的的谷歌或雅虎的搜索引擎。由于数据室同时提供给你的实际搜索结果，Firfox搜索引擎优化的扩展甚至允许你在访问之前可以检查最重要的统计资料。一些统计数据所提供的搜索引擎优化用语Firefox的快速检视，包括谷歌的pagerank，雅虎网页和域的链接及一些反向链接。这些统计信息是有价值的信息，一起使用时可以给你一个有明确图片的相关性很强的网站。雅虎和msn的报告指出用于Firefox的搜索引擎优化提供了一个非常有用的用来衡量的反向链接数的网页和网站。那些链接数和主题相关的网站的反向链接是两个最重要的场外因素，搜索引擎优化使用的优化搜索引擎的排名位置确定有机搜索引擎的结果。Firefox搜索引擎优化的反向指标提供的反向链接数来自网页的教育领域，它通常是一个任何特定网页的site.link的主要质量指标。教育领域的域名一般被认为是更值得信赖的，因为相比其他领域扩展，如com和info，它更难以实现。Firefox的搜索引擎优化扩展提供了一个有用的功能，可以让你查找统计资料的网页，只需要右键点击网页上的任何地方，从Firefox出现的菜单中选择搜索引擎优化，然后点击查找此网页。此功能将返回所有的数据，特别是网页，而你不需要从谷歌或雅虎中搜索，它为你节省大量的时间并为你评估网页。Firefox的搜索引擎优化扩展是资源密集型，它会被警告，因为它立刻从搜索引擎后端系统调用数据。出于这个原因，你做的日常冲浪应该延长关闭，并使用它只有当你正在做市场调研。设置数据取自需求，而不是另一个选择自动。用于Firefox的搜索引擎优化经历了多个升级，所以未来的升级和改进有可能发生。据搜索引擎优化专家Aaron Wall统计，Firefox的搜索引擎优化扩展，目前正在使用的网站管理员和互联网专业人员有5万多个。目前在网络上wordpress已经成为最流行的博客内容管理系统网。然而，开箱默认版本的wordpress是有限的搜索引擎优化的观点。一个主要缺点在于其处理标题标记的page.given，是一个决定排名的更重要的因素，这是一个值得密切关注的问题。默认设置wordpress的地方的名称、职务或文章的标题标记后的个人网页的设置并不总是理想的。当你写职衔从文案的角度看，你想他们容易读并提醒读者主要当创建的标题标记网页时，要正确使用你的目标关键词，以及同义词和其他语义联系关键词。这两个重要的搜索引擎优化的考虑往往并不符合多方需要。搜索引擎优化标题标记插件解决了这个问题，允许你自定义标题标记你的网站的每个网页，而不做有关你的帖子标题的任何调整。现在你可以是虚名，你的读者和关键字都很丰富，并达到标题搜索引擎排名靠前的目的。这可以防止你过多投入到你的网站，节省大量时间。相反，你也可以花呢的时间写作两个不同的标题，每一个服务的目的远优于混合标题。搜索引擎优化标题标记插件，可以设置标题标记为次要的网页。如404错误页面，或标记的网页。404错误页面时，会出现访问者尝试访问的网页不存在你的网站上。当然，你不想标题是适合你的错误网页的排名，但在这种情况下，插件被用来提供简明扼要的名称代替。如果你决定使用一个标签云网站，那每个标签都有自己的网页。标签云是一个直观描绘用户生成的标签。因为特别标记，每个网页上列出了所有的帖子。该插件可以让你轻易地操纵标题标记的每个标签页。使用搜索引擎优化标题标记插件的一个主要优势是他可以让你快速增加自定义标题标记你的网站的内部搜索结果页上。这可以大大增加你的网站的网页数量，那你就有几百页索引相同的确切名称。默认的wordpressdoes开箱版本没有系统化的描述元标记。但是wordpress的说明标签插件，可以让你能够轻松地优化描述元标记。虽然关键字和描述元标记没有过去那样受到重视，但使用它们任然是一个很好的习惯，在将来它们的权重可能会增加。这些标记元的描述保留了最大的价值。通常情况下，这些标记事宜简短描述片段的形式显示在搜索引擎的结果网页上。Wordpress中的添加元标记插件提供了几种选择可以优化你的中继标记的选择。第一种选择允许添加meta标签插件来自动填入说明标签。虽然此选项描述是自动标记，但他的摘录的内容是从不确定的网页描述上得到的，所以并不理想。如果你希望拥有更多控制权，第二个选项允许你用自定义描述元标记你网站的每个网页。如果你的网站有数百网页，这可能是一个乏味你任务。如果你感刚起步，憧憬未来，这就算不上什么。添加你的网页的自定义描述只需要几秒钟。稍微时兴的插入元标签是返回已经排名好标签的网页。如果描述的中继标记以两行形式显示的搜索引擎网页，可能影响你的点击率。这就需要不断地测试，但测试的回报形式是要找到更好的描述。除了提供给你优化了的元描述标签，添加wordpress的元标记插件可以优化你的中继关
