　　在山東做網站優化，友情鏈接交換是提升網站權重和流量的常用手段。但換鏈接不是隨便找個網站掛上就行，里面有很多門道。今天咱們就聊聊，在山東做網站優化時，換友情鏈接到底要注意哪些事。
　　In Shandong, website optimization and friendly link exchange are common methods to increase website weight and traffic. But changing links is not just about finding a website to hang on, there are many tricks inside. Today we will talk about what to pay attention to when changing friendship links when doing website optimization in Shandong.
　　首先，得找對“搭檔”。友情鏈接的本質是資源互補，所以最好選和自己網站內容相關或行業上下游的網站。比如你是做山東旅游攻略的，找當地美食、酒店類的網站就挺合適。如果對方網站八竿子打不著，比如賣機械設備的，那交換了也沒啥用，搜索引擎可能都不認這個“友情”。
　　Firstly, we need to find the right 'partner'. The essence of friendship links is complementary resources, so it is best to choose websites that are related to your website content or upstream and downstream in the industry. For example, if you are making travel guides to Shandong, finding local food and hotel websites would be quite suitable. If the other party's website is completely unrelated, such as selling mechanical equipment, then exchanging it is useless, and search engines may not recognize this "friendship".
　　其次，得看對方網站的“底子”。這包括幾點：一是看備案信息，有備案的網站相對穩定，不容易突然關門大吉；二是看網站結構，結構清晰、層級淺（最好不超過三層）的網站更受搜索引擎喜歡；三是看內容質量，原創內容多、更新頻繁的網站，權重一般更高。
　　Secondly, we need to look at the "foundation" of the other party's website. This includes several points: firstly, looking at the filing information, websites with filing are relatively stable and not easily shut down suddenly; The second is to look at the website structure. Websites with clear structure and shallow hierarchy (preferably no more than three layers) are more favored by search engines; The third factor is the quality of the content. Websites with more original content and frequent updates generally have higher authority.

　　再來說說鏈接質量。有些網站看著權重高，但導出鏈接一大堆，像“批發”鏈接似的，這種要小心。因為導出鏈接越多，分給你的權重就越少。一般建議，對方網站的導出鏈接別超過40個。另外，如果對方給你的鏈接是放在JS代碼里或者用iframe框架嵌套的，這種鏈接對優化沒啥幫助，直接拒絕就行。
　　Let's talk about link quality again. Some websites may appear to have high authority, but they export a lot of links, like "wholesale" links, so be careful. Because the more exported links, the less weight will be assigned to you. It is generally recommended that the export links of the other party's website do not exceed 40. In addition, if the link given to you by the other party is placed in JS code or nested with an iframe framework, this type of link is not helpful for optimization, just reject it directly.
　　還有幾個細節不能忽視。一是看對方網站有沒有被降權或者被K的經歷。可以用站長工具查查歷史快照，如果快照長時間不更新，或者收錄量突然暴跌，那可能是有問題。二是別和作弊網站交換鏈接，比如那些用黑帽SEO手段刷排名的，萬一被搜索引擎發現，你也可能被牽連。三是鏈接位置要顯眼，最好放在首頁或者內容頁的正文區域，別藏在 footer 里或者側邊欄底部，這樣用戶看不到，搜索引擎也可能不重視。
　　There are still a few details that cannot be ignored. One is to check if the other party's website has experienced being downgraded or penalized. You can use webmaster tools to check historical snapshots. If the snapshot is not updated for a long time or the indexing volume suddenly drops sharply, it may be a problem. Secondly, do not exchange links with cheating websites, such as those that use black hat SEO methods to boost rankings. If they are discovered by search engines, you may also be implicated. Thirdly, the link position should be prominent, preferably placed in the main body area of the homepage or content page, and not hidden in the footer or at the bottom of the sidebar, so that users cannot see it and search engines may not attach importance to it.
　　最后，換完鏈接不是就完事了，得定期“體檢”。比如檢查對方網站是不是還正常運營，鏈接有沒有被刪除或者加上nofollow標簽（這種鏈接不傳遞權重）。如果發現對方網站有問題，或者鏈接失效了，趕緊聯系對方修復，或者干脆撤掉鏈接，別讓“壞鄰居”拖垮你的網站。
　　Finally, changing the link is not enough, regular "health check ups" are necessary. For example, checking whether the other party's website is still operating normally, whether the links have been deleted or added with nofollow tags (which do not pass weight). If you find that there is a problem with the other party's website or the link is invalid, contact them immediately to fix it, or simply remove the link, don't let the "bad neighbor" drag down your website.
　　總之，在山東做網站優化，換友情鏈接得像挑合作伙伴一樣謹慎。找對行業、看好質量、盯緊細節，才能讓友情鏈接真正成為提升網站權重的“助推器”。
　　In short, when optimizing a website in Shandong, changing friendship links should be as cautious as choosing a partner. Only by finding the right industry, focusing on quality, and paying close attention to details can friendship links truly become a "booster" to enhance website weight.
