源代码网推荐 源代码网推荐 源代码网推荐1.)Why don"t all my links show up when I use the link: command? 源代码网推荐 源代码网推荐A. At this moment Google is only showing a sampling of the total links to you. 源代码网推荐A few months ago it seemed as though they were only showing those backlinks which 源代码网推荐were PR4 or higher. This has, however, changed and which links Google chooses 源代码网推荐to show is now a topic of debate. As far as numbers, it is only important to remember 源代码网推荐it is a sampling and to just continue your link building strategy. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐2.)How come I get a different amount of links when I use www.example.com 源代码网推荐and example.com? 源代码网推荐 源代码网推荐A. In the search engines eyes, these are two different domains and therefore have 源代码网推荐different amounts of sites linking to them. It is best to be sure your link partners 源代码网推荐are only linking to one of these as it would be considered extremely rare for 源代码网推荐both "domains" to rank high at the same time. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐3.) What"s a Link Farm? 源代码网推荐 源代码网推荐A. A set of web pages that have been built for the sole purpose of increasing 源代码网推荐the number of incoming links to a web site. This is done in order to increase 源代码网推荐link popularity and search engine rankings. Link farms usually require a reciprocal 源代码网推荐link from sites seeking listings. Link farms are a known spam tactic and sites 源代码网推荐that participate in them are likely to be penalized or banned from the major search 源代码网推荐engines. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐4.) What is "Anchor Text"? 源代码网推荐 源代码网推荐A:Anchor text is the text that you use within a html link. 源代码网推荐 源代码网推荐For example ( This is Anchor Text 源代码网推荐) 源代码网推荐 源代码网推荐The anchor text that you use, should reflect the keywords of which you are trying 源代码网推荐to get a higher listing for. It should also accurately describe what information 源代码网推荐will be found on the next page if you click on the link. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐5.) What is an "IBL"? 源代码网推荐 源代码网推荐A: An "IBL" is an "In Bound Link". When a site links to yours, that 源代码网推荐link is an IBL. The same thing as a BL (Backlink). back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐6.) What is cross linking? 源代码网推荐 源代码网推荐A: When multiple sites link to each other for the purpose of increasing link popularity. back to top 源代码网推荐 源代码网推荐7.) How long after I am listed in DMOZ should I start to gain the benefit of the "4000" new links? 源代码网推荐A: It usually takes close to a month for your listing to show up in Googles Directory which is the most common asked about one. Then to gaine the full benefit it many times takes 1 - 2 years to fully propogate. This is a good way to make sure all links realize their full potential as that slow growth is something that Google seems to like. back to top 源代码网推荐 源代码网推荐8.) Would I be penalized if a "Link Farm" or a "Bad Neighborhood" linked to my site? 源代码网推荐A: No, you have no control over who links to you and this would be an easy way for a competetior to sink your site. What you SHOULD be careful of is if you are linking to them. This CAN hurt your site and should be avoided. 源代码网推荐 源代码网推荐 源代码网推荐Search Engine Optimization 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐1.) How do I use a Robots file or do you have an example of one? 源代码网推荐 源代码网推荐A. You mean robots.txt. It"s a file in the main directory of a website which tells 源代码网推荐the search engine spiders where they are allowed to go. 源代码网推荐 源代码网推荐A basic, spider can go anywhere file is: 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐User-agent: * 源代码网推荐 源代码网推荐Disallow: 源代码网推荐 源代码网推荐You can disallow folders or files by putting this into the file: 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐User-agent: * 源代码网推荐 源代码网推荐Disallow: /foldername/ 源代码网推荐 源代码网推荐back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐2.) Should I use a Site Map? and does anyone have an example of one? 源代码网推荐 源代码网推荐A: Every site should have a sitemap of some sort. It provides a way for visitors 源代码网推荐to navigate your site, as well as a shortcut for bots to crawl all your pages. 源代码网推荐Google for "sitemap" and you"ll find nice examples, although it would 源代码网推荐be advisable to follow Google"s official guidelines and keep the number of links 源代码网推荐per page under 100. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐3.) How do I tell how many people are searching for my keywords? 源代码网推荐 源代码网推荐A: The Search Term Suggestion Tool here 源代码网推荐will show you number of searches per month on Overture"s network. You can also 源代码网推荐use Digital Points Keyword 源代码网推荐Suggestion Tool back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐4.) What are SERPs? 源代码网推荐 源代码网推荐A: Search Engine Result Pagesback to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐5.). I am number 5 in Yahoo, but not in the top 1,000 in Google. Why? 源代码网推荐 源代码网推荐A. Yahoo and Google use two different algos to come up with their SERPs - Yahoo 源代码网推荐favors on- page optimization such as H1 tags, keyword density, etc while Google 源代码网推荐favors off page like in bound links. If you have done more on page then Yahoo 源代码网推荐will rank higher and vice versa. As part of this if you are now addressing your 源代码网推荐off page then you need more backlinks with anchor text and time for these links 源代码网推荐to age (Google lag). back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐6.) Is there a way I can find out where I rank? 源代码网推荐 源代码网推荐A: There are two sites you can use if you are just checking a few keywords - 源代码网推荐www.googlerankings.com for Google and www.yahoosearchrankings.com/ for Yahoo. 源代码网推荐If you are looking to track multiple keywords over time then the best (and free) 源代码网推荐tool is Digital Points Keyword Monitor at 
源代码网推荐(Google Only) back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐7.) What is an "ALGO" ? 源代码网推荐 源代码网推荐A: An "Algo" is an abbreviation of "Algorithm". (In short, the mathematical 源代码网推荐formula or calculation that Google use in order to rank websites.) back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐8.) What is Hidden Text? 源代码网推荐 源代码网推荐A: Text that is visible to the search engine spiders but not to site visitors. 源代码网推荐Hidden text is primarily used to add extra keywords in the page without actually 源代码网推荐adding content to a site which may mostly consist of images. Most search engines 源代码网推荐will penalize Web sites which use hidden text. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐9.) What is cloaking? 源代码网推荐 源代码网推荐A: Determining which search engine spider is visiting a web page and then giving 源代码网推荐each spider a page optimized for it"s particular algorithm. This method of search 源代码网推荐engine optimization can result in a website being removed from the major search 源代码网推荐engines. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐10.) What is a doorway page? 源代码网推荐 源代码网推荐A: A method of search engine optimization considered to be SPAM. These are pages 源代码网推荐created for nothing but the purpose of ranking first for a particular keyword 源代码网推荐phrase. These pages usually lack any significant content and do not reflect 源代码网推荐the tone of the rest of the website. If a search engine determines a website 源代码网推荐has used this tactic then the website will be removed from the search engine 源代码网推荐permanently. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐11.) What is Geo Targeting? 源代码网推荐 源代码网推荐A: The distribution of ads to a particular geographical area. For example, you 源代码网推荐can use a place name in your keyword, such as "Texas Web Design". 源代码网推荐Some search engines allow you to target specific countries – and languages 源代码网推荐– without using keyword relevance. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐12.) Do XHTML pages rank better than HTML-pages? 源代码网推荐 源代码网推荐A: No. They have the same value. Google however puts more weight to well structured 源代码网推荐content, and thus XHMTL is in most cases more suitable option. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐13.) Does using CSS affect my rankings? 源代码网推荐 源代码网推荐A: Not directly. Googlebot does not (at the moment) read CSS-files. Using CSS 源代码网推荐makes pages lighter, and page structure more organized. Thus using CSS could 源代码网推荐lead to better rankings. When adding CSS styles to page, it is recommend to 源代码网推荐put them to external file (using link-tag). back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐14.)Should I use submission software to make sure all the search engines have 源代码网推荐me included? 源代码网推荐 源代码网推荐A: Most submission programs that promise to "Submit Your Site to 1000"s 源代码网推荐of Search Engines" are used to harvest your email address for spammers. 源代码网推荐The truth is there are only a handful of Search Engines used by enough people 源代码网推荐to justify a submission and these can all be submitted by hand. Even better 源代码网推荐yet is to get other sites to link to you. Search Engine spiders follow these 源代码网推荐links and you will be indexed naturally. Submission programs are unnecessary 源代码网推荐and may actually hurt you. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐15.) I submitted to DMOZ but didn"t hear anything. Should I resubmit? 源代码网推荐 源代码网推荐A: You should only submit once as resubmitting only deletes your original request 源代码网推荐and lengthens your wait. Resubmitting too many times can have you classified 源代码网推荐as SPAM and blocked. You can also submit to a "normal" category and 源代码网推荐a "regional" one if it fits. You must be physically located somewhere 源代码网推荐to be able to also submit to regional and read their guidelines as certain sites 源代码网推荐like real estate are the exception. They have set up a forum as a way of letting 源代码网推荐you know your status and this is a much under posted and under used area of 源代码网推荐DMOZ - The address is . Just remember to
源代码网推荐take the time to follow the posted directions. 源代码网推荐 源代码网推荐Google General 源代码网推荐 源代码网推荐 源代码网推荐1.) What is the "Sandbox Theory"? 源代码网推荐 源代码网推荐The sandbox theory proposes that Google has a unique ranking element in their algorithm that has been affecting sites whose major SEO efforts began after March of 2004 (this would include all sites registerd after this date). The criteria, elements and solution of the "sandbox" have not yet been identified or publicized by the SEO community, but ongoing discussion and testing have determined that the two of the most likely issues creating the sandbox could be: 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐Age of backlinks - older backlinks now carry greater weight at Google 源代码网推荐 源代码网推荐SEO specific filters - Google is actively attempting to filter sites out of their index that are actively optimizing (link-building, etc) or appear to have un-natural attributes (optimized pages, links, anchor text, etc.) 源代码网推荐 源代码网推荐 源代码网推荐If your site is ranking well for specific keyword phrases at engines like Yahoo!, Teoma, MSN & for the allin sets of searches at Google (allinanchor:, allintitle:, allintext:, etc.) but not listed in the top 50-100 results at Google, the sandbox effect may be at work. However, it is important to keep in mind that this phenomenon is an "unknown" algorithm piece at Google and standard optimization tactics, even by some of the best and most experienced SEOs have yet to consistently beat this effect. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐2.) When does Google update their SERPs (When is the "dance")? 源代码网推荐 源代码网推荐A. There is no longer a Google "dance" per se as SERPs tend to be 源代码网推荐updated constantly. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐3.) I now use the link: command all the time, is there a list of the 源代码网推荐other commands I can use in Google? 源代码网推荐 源代码网推荐link:www.domain.com (returns a list of backlinks that google has indexed. Only 源代码网推荐a small selection is listed however.) 源代码网推荐 源代码网推荐related:www.domain.com (returns a list of sites that google sees as related 源代码网推荐to the topic on your page. At present, not very accurate.) 源代码网推荐 源代码网推荐allinurl:keyword (returns a list of pages and sites that contain the "keyword" 源代码网推荐in their url.) 源代码网推荐 源代码网推荐site:www.domain.com (returns all pages of the domain that google has crawled 源代码网推荐and indexed.) 源代码网推荐 源代码网推荐allinanchor:keyword (returns a list of pages and sites that contain the keyword 源代码网推荐as anchor text in their backlinks.) 源代码网推荐 源代码网推荐cache:www.domain.com (will show the current cache that google has for the page) 源代码网推荐 源代码网推荐info:www.domain.com (will return information that google has for the page) 源代码网推荐 源代码网推荐allintitle:keyword (returns webpages that have the specified keywords in the 源代码网推荐title) 源代码网推荐 源代码网推荐intitle:keyword (returns listings of webpages that have only the specific keyword 源代码网推荐as the title.) 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐You can find all the Operators at Google 源代码网推荐Advanced Operators back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐4.) Am I banned in Google? 源代码网推荐 源代码网推荐A: You can tell if you are banned or not indexed in google, by using the "site:" 源代码网推荐command in Google"s search. 源代码网推荐 源代码网推荐(ie. site:www.domain.com) back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐5.) What is the first thing you would check for if you saw your site 源代码网推荐slip down the listings at Google? ( i.e. I"m not on top anymore, what happened? 源代码网推荐) 源代码网推荐 源代码网推荐A: A drop in backlinks. Obviously when not aggressively acquiring new backlinks 源代码网推荐to your site from day to day, existing backlinks may even deteriorate in value. 源代码网推荐The referring site may disappear, be changed, lose relevance or lose PR itself, 源代码网推荐reducing the PR that is passed onto you. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐6.) When I look up my site in Google, I am #23, but when my friend in 源代码网推荐California looks it up I am #31. Which one is right? 源代码网推荐 源代码网推荐A: They both are! Actually, a more accurate explanation is that Google using 源代码网推荐multiple datacenters that deliver the results you see. The datacenter that is 源代码网推荐used depends on your geographical location. It is very common to see a small 源代码网推荐difference in results depending where you are. Sometimes, results can differ 源代码网推荐when you move just a few miles away! back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐7.) Why does Google hate me/pick on me? 源代码网推荐 源代码网推荐A: "Google" does not pick on individual sites but instead allows complex 源代码网推荐mathematical equations to decide the value of your site in any particular search. 源代码网推荐Although it may sometimes feel like they are picking on you, most times a ban 源代码网推荐or bad results can be traced to a small piece of bad or misguided SEO. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐8.) Should I submit my website to Google every month? 源代码网推荐 源代码网推荐A: No, you only need to do it once. In most cases you will not even need to 源代码网推荐submit your website to Google. If you are active in building links to your website 源代码网推荐then Googlebot will frequent your site soon, and thus include it in the index. 源代码网推荐back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐9.) My site is not cached in Google, I"ve submitted it to google numerous 源代码网推荐times but I"m not seeing the googlebot crawl my entire site. I"m also seeing 源代码网推荐an incomplete listing. 源代码网推荐 源代码网推荐A: Sometimes the googlebot will visit, and leave, only to come back at a later 源代码网推荐time in order to crawl all of your pages. If a site has no cache, or an incomplete 源代码网推荐listing, it has not been crawled and indexed properly yet. The best thing you 源代码网推荐can do is get more in bound links to your site, so that the googlebot arrives 源代码网推荐to your site from more than 1 source. 源代码网推荐 源代码网推荐Page Rank 源代码网推荐 源代码网推荐 源代码网推荐1.) I am changing my domain but want to keep my PR, how do I do it? 源代码网推荐 源代码网推荐A 301 redirect is the most efficient and spider/visitor friendly strategy around 源代码网推荐for web sites that are hosted on servers running Apache (check with your hosting 源代码网推荐service if you aren"t sure). It"s not that hard to implement and it should preserve 源代码网推荐your search engine rankings for that particular page. If you *have* to change 源代码网推荐file names or move pages around, it"s the safest option. If you are unfamiliar 源代码网推荐with editing your .htaccess file, you should ask your hosting company for help. 源代码网推荐back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐2.) I have a new site but it has no PR .I have backlinks, etc When does 源代码网推荐it update? 源代码网推荐 源代码网推荐A. It updates internally every day or so, (every time google"s spider follows 源代码网推荐a link through to your site) you may see a difference in the SERPs very soon, 源代码网推荐however you will not see the backlink appear in a link:www.domain.com command 源代码网推荐search in google, until google do an official backlink update. back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐3.) I noticed my PR in the Google directory is different from my PR 源代码网推荐on the toolbar, Why? 源代码网推荐 源代码网推荐A:This is because the google directory gets its listings from DMOZ. As with 源代码网推荐google"s PR and backlink updates, it only updates its directory every so often, 源代码网推荐so your site may be showing an old PR. 源代码网推荐 源代码网推荐There are also a host of "theories" such as "Googles Directory 源代码网推荐is on a scale of 0 to 8" and "The Directory PR is actually a comparison 源代码网推荐between you and other sites in the Directory". No matter what you may believe, 源代码网推荐it is most important to state that they rarely match and this is VERY common. 源代码网推荐back to top 源代码网推荐 源代码网推荐 源代码网推荐 源代码网推荐4.) When does Google update backlinks and PR? 源代码网推荐 源代码网推荐A: There isn"t a set schedule as many times an update is skipped or late. Backlinks 源代码网推荐on average are updated around once a month while PR has seemed to move to quarterly. 源代码网推荐The best way to "guess" when the next update will be is to utilize 源代码网推荐the SEOChat Calendar 上一页12 下一页 源代码网供稿. |
