Welcome to Google'sSearch Engine OptimizationStarter GuideThis document first began as an effort to help teams within Google,but we thought it'd be just as useful to webmasters that are new tothe topic of search engine optimization and wish to improve theirsites' interaction with both users and search engines. Although thisguide won't tell you any secrets that'll automatically rank your sitefirst for queries in Google (sorry!), following the best practicesoutlined below will make it easier for search engines to crawl, indexand understand your content.Search engine optimization is often about making small modificationsto parts of your website. When viewed individually, these changesmight seem like incremental improvements, but when combined withother optimizations, they could have a noticeable impact on yoursite's user experience and performance in organic search results.You're likely already familiar with many of the topics in this guide,because they're essential ingredients for any web page, but you maynot be making the most out of them.Even though this guide's title contains the words "search engine",we'd like to say that you should base your optimization decisions firstand foremost on what's best for the visitors of your site. They're themain consumers of your content and are using search engines to findyour work. Focusing too hard on specific tweaks to gain ranking in theorganic results of search engines may not deliver the desired results.Search engine optimization is about putting your site's best footforward when it comes to visibility in search engines, but yourultimate consumers are your users, not search engines.Your site may be smaller or larger than our example site and offervastly different content, but the optimization topics we discuss belowshould apply to sites of all sizes and types. We hope our guide givesyou some fresh ideas on how to improve your website, and we'd loveto hear your questions, feedback, and success stories in the GoogleWebmaster Help Forum.

SEO BasicsCreate unique, accurate page titlesIndicate page titles by using title tagsA title tag tells both users and search engines what the topic ofa particular page is. The title tag should be placed within the head tag of the HTML document (1). Ideally, you should create aunique title for each page on your site. html head title Brandon's Baseball Cards - Buy Cards, Baseball News, Card Prices /title meta name "description " content "Brandon's Baseball Cards provides alarge selection of vintage and modern baseball cards for sale. We also offerdaily baseball news and events in" /head body Page title contents are displayed in searchresults(1) The title of the homepage for our baseball card site, which lists the businessname and three main focus areas.If your document appears in a search results page, the contents ofthe title tag will usually appear in the first line of the results (ifyou're unfamiliar with the different parts of a Google search result,you might want to check out the anatomy of a search result video byGoogle engineer Matt Cutts, and this helpful diagram of a Googlesearch results page). Words in the title are bolded if they appear in theuser's search query. This can help users recognize if the page islikely to be relevant to their search (2).The title for your homepage can list the name of your website/business and could include other bits of important information likethe physical location of the business or maybe a few of its mainfocuses or offerings (3).(2) A user performs the query [baseball cards]. Our homepage shows up as a result,with the title listed on the first line (notice that the query terms the user searchedfor appear in bold).If the user clicks the result and visits the page, the page's title will appear at the topof the browser.(3) A user performs the query [rarest baseball cards].

SEO BasicsMake use of the "description" meta tagSummaries can be defined for each pageA page's description meta tag gives Google and other searchengines a summary of what the page is about (1). Whereas apage's title may be a few words or a phrase, a page's description metatag might be a sentence or two or a short paragraph. GoogleWebmaster Tools provides a handy content analysis section that'll tellyou about any description meta tags that are either too short, long, orduplicated too many times (the same information is also shown for title tags). Like the title tag, the description meta tag is placedwithin the head tag of your HTML document. html head title Brandon's Baseball Cards - Buy Cards, Baseball News, Card Prices /title meta name "description " content "Brandon's Baseball Cards provides alarge selection of vintage and modern baseball cards for sale. We also offerdaily baseball news and events in" /head body (1) The beginning of the description meta tag for our homepage, which gives a briefoverview of the site's offerings.What are the merits of description metatags?Description meta tags are important because Google might usethem as snippets for your pages. Note that we say "might" becauseGoogle may choose to use a relevant section of your page's visibletext if it does a good job of matching up with a user's query.Alternatively, Google might use your site's description in the OpenDirectory Project if your site is listed there (learn how to preventsearch engines from displaying ODP data). Adding description metatags to each of your pages is always a good practice in case Googlecannot find a good selection of text to use in the snippet. TheWebmaster Central Blog has an informative post on improvingsnippets with better description meta tags.(2) A user performs the query [baseball cards]. Our homepage appears as a result,with part of its description meta tag used as the snippet.Words in the snippet are bolded when they appear in the user's query(2). This gives the user clues about whether the content on the pagematches with what he or she is looking for. (3) is another example,this time showing a snippet from a description meta tag on a deeperpage (which ideally has its own unique description meta tag)containing an article.(3) A user performs the query [rarest baseball cards].

If your site has thousands or even millions of pages, hand-crafting description meta tagsprobably isn't feasible. In this case, you could automatically generate description meta tags based oneach page's content.Avoid:using a single description meta tag across all of your site's pages or a large group of pagesDealing with CrawlersUse description meta tags toprovide both search enginesand users with a summary ofwhat your page is about!SEO for Mobile PhonesPromotions and AnalysisLinksContent analysis sectionh new-content-analysis-andsitemap.htmlPrevent search engines from displaying ODP 35264Improving snippets with better description meta tagsh improve-snippets-withmeta-description.htmlsite: e-site-operator-an-ode-to-thee/

Improving Site StructureImprove the structure of your URLsSimple-to-understand URLs will conveycontent information easilyCreating descriptive categories and filenames for the documents onyour website can not only help you keep your site better organized,but it could also lead to better crawling of your documents bysearch engines.

Visitors may be intimidated byextremely long and cryptic URLs that contain few recognizable words.(1) A URL to a page on our baseball card site that a user might have a hard timewith.(2) The highlighted words above could inform a user or search engine what thetarget page is about before following the link.URLs like (1) can be confusing and unfriendly. Users would have ahard time reciting the URL from memory or creating a link to it. Also,users may believe that a portion of the URL is unnecessary, especiallyif the URL shows many unrecognizable parameters. They might leaveoff a part, breaking the link.Some users might link to your page using the URL of that page as theanchor text. If your URL contains relevant words, this providesusers and search engines with more information about the pagethan an ID or oddly named parameter would (2).URLs are displayed in search resultsLastly, remember that the URL to a document is displayed aspart of a search result in Google, below the document's title andsnippet. Like the title and snippet, words in the URL on the searchresult appear in bold if they appear in the user's query (3). To the rightis another example showing a URL on our domain for a pagecontaining an article about the rarest baseball cards. The words in theURL might appeal to a search user more than an ID number like "" would.(3) A user performs the query [baseball cards]. Our homepage appears as a result,with the URL listed under the title and snippet.Google is good at crawling all types of URL structures, even if they'requite complex, but spending the time to make your URLs as simple aspossible for both users and search engines can help. Somewebmasters try to achieve this by rewriting their dynamic URLs tostatic ones; while Google is fine with this, we'd like to note that this isan advanced procedure and if done incorrectly, could cause crawlingissues with your site.

Improving Site StructureMake your site easier to navigateNavigation is very important for searchengines(root)aboutThe navigation of a website is important in helping visitorsquickly find the content they want. It can also help search enginesunderstand what content the webmaster thinks is important.Although Google's search results are provided at a page level, Googlealso likes to have a sense of what role a page plays in the biggerpicture of the site.articlesnews2008Plan out your navigation based on yourhomepage20092010All sites have a home or "root" page, which is usually the mostfrequented page on the site and the starting place of navigation formany visitors. Unless your site has only a handful of pages, youshould think about how visitors will go from a general page(your root page) to a page containing more specific content. Doyou have enough pages around a specific topic area that it wouldmake sense to create a page describing these related pages (e.g. rootpage - related topic listing - specific topic)?

For example, instead of using the breadcrumb linkson the page, a user might drop off a part of the URL in the hopesof finding more general content. He or she might be visiting oming-baseballcard-shows.htm, butthen enter intothe browser's address bar, believing that this will show all news from2010 (2).

Improving Site StructureMake your site easier to navigateBest PracticesCreate a naturally flowing hierarchyMake it as easy as possible for users to go from general content to the more specific content theywant on your site. Add navigation pages when it makes sense and effectively work these into yourinternal link structure.Avoid:creating complex webs of navigation links, e.g. linking every page on your site to every other pagegoing overboard with slicing and dicing your content (so that it takes twenty clicks)Use mostly text for navigationControlling most of the navigation from page to page on your site through text links makes it easier forsearch engines to crawl and understand your site. Many users also prefer this over other approaches,especially on some devices that might not handle Flash or JavaScript.Avoid:having a navigation based entirely on drop-down menus, images, or animations- many, but not all, search engines can discover such links on a site, but if a user can reach allpages on a site via normal text links, this will improve the accessibility of your site; more on howGoogle deals with non-text filesFor navigation, the focusshould be on simplicityand ease of use!Glossary12FlashWeb technology or software developed by Adobe Systems Incorporated.

Having a custom 404 page that kindly guides users back to a workingpage on your site can greatly improve a user's experience. Your 404 page should probably have a linkback to your root page and could also provide links to popular or related content on your site.
