owners often ask Jiang Ping, my site is not to be K, and how my site included reduced, how my site ranking and so on down ... ... . Why, then, would lead to these problems? In fact, the operation of SEO, they must avoid the search engines will be considered SPAM, the search engine will be a show by the following methods to determine whether the site is SPAM:
(1) the domain name, IP address, the number of links
This approach is generally check whether the site provides links to services dedicated page. If too many outgoing links on this page, then search engines may identify site is SPAM. Of course, the navigation site is not on that list. Such as search engine hao123, 265, DMOZ and other sites have their own algorithms and different coping styles.
approach: when doing link with particular attention, not to be punished in the website has links to export, do not over too many pages in a page of external links.
(2) to determine the keyword density of
In fact, the accumulation of this keyword is very easy to be identified as SPAM the search engines. For example, Jiang Ping made in a recent experiment in a "diet blog" adding a lot of weight above the keywords, such as in the title, description technique, keywords and other places all join the "weight loss diet, weight errors, weight charts, diet pills, exercise to lose weight, belly weight, lose weight, lose weight quickly, lazy to lose weight, lose weight often "series keyword, the search engines easily identified as SPAM, then the page will not be included, but did not accumulate inside pages the contrary, are a collection of. General keyword density control at 7% or less is best.
approach: control in the page's keywords 3% -7% of the most appropriate.
(3) page similarity analysis
as many pages the same domain name is identical or similar content, search engines will be identified as Web site is SPAM. Of course, some owners inadvertently made a number of articles the same article, the article had been made today once again made. Well, the owners may have to pay attention to select the best choice when the program repeated that the title will be prompted to release the CMS or blog system. For example: Dedecms its content will be prompted to repeat the title, phpwind the release of the same content presented will have several tips.
approach: each page of the site must be unique content, do not access a page in several addresses.
(4) appeared objectionable content or users boast content
Keywords correlation between the samples from the training and non-SPAM SPAM samples obtained. General page appears "free" or "Lyrics" is not to be judged as SPAM, but also a "free" and "Lyrics" can be considered SPAM. For example, the profit for the exchange launched the "SEO Engineer", registration unit of China Electronic Commerce Association. So, the SEO engineers are not certified the official launch of the search engine, search engine is likely to launch its offensive series of the SEO certification training, it may also be identified SPAM. Also, some well-known station group well-known collector software and search engines have also been suppressed, because this is prohibited by the search engines, such as: knight-station group and the Madman collector, and so on.
approach: to avoid such "free lottery", "free winning activities", "SEO certification", "free ringtones" and other users or search engines key objectionable the word.
(5) the establishment of SPAM blacklist
like a cheat server IP or domain name has been recorded many times by search engines, then the search engine directly to into the blacklist or the observation period pending the library. So, if you do this type of link to be punished with the inter-chain will be joint and several liability. Such as: Jiang Ping of station owners has worked with crazy knight collected each organ network chain, and later found to be K lead warrior station station owners have been down the right treatment.
approach: register a domain name before, check whether the domain name was registered before the penalty too. Select the server, check whether the domain name IP below punished by search engines too. Do not do the Friends of the chain over the site with SPAM each chain.
(6) comments Comments trap
had established a number of their own Blog, then open the article Comments and other functions. This automatic message when some program or when the garbage outside the chain was recorded message, then become a "trap" of its own Blog will likely be down the right. Such as: Lu Songsong blog original PR5, then open a blog post a message function, resulting in about 500-800 comments a day, followed by the all the contents of the message with the link, it may leave some spam links, leading to weight dropped to PR3 blog .
approach: if the site has BLOG System, Guestbook etc., to note the contents of messages, check whether there are links to spam chain. If too much waste chain, the chain can be considered critical reviews, open only to comment on the content, of course, the results of doing so many webmasters do SEO is no longer message, blog popularity may be affected. It all depends on popularity or weight owners, and of course the weight of the popular blog's certainly not bad.
