Robots協(xié)議文件能夠幫助你告訴Googlebot哪些頁(yè)面是不想要去掃描并收錄到Google上的。
網(wǎng)站優(yōu)化中怎樣盡量減少無(wú)效URL的爬行和索引
1. 合理設(shè)計(jì)URL：在構(gòu)建鏈接時(shí)，應(yīng)該避免使用太多參數(shù)或者不必要的參數(shù)。同時(shí)也要注意URL中是否存在特殊字符，如“&”、“?”以及其它有特殊意義的字符。這些特殊字符會(huì)導(dǎo)致瀏覽器生成大量的無(wú)效請(qǐng)求。
2. 使用robots協(xié)議文件拒絕不必要的內(nèi)容：Robots協(xié)議文件能夠幫助你告訴Googlebot哪些頁(yè)面是不想要去掃描并收錄到Google上的。通過(guò)Robots協(xié)議文件來(lái)告訴Googlebot你想要隱藏或者不想去掃描并收錄到Google上的內(nèi)容，這樣就能有效凈化你站內(nèi)部得到 Google 索引而且保留真正有用得 URL 頁(yè)面。
3. 進(jìn)行404頁(yè)面優(yōu)化: 404 Not Found 是一個(gè)HTTP 狀態(tài)代碼, 表明服務(wù)器上找不到相應(yīng)請(qǐng)求得 URL 內(nèi)容, 即 “Not Found". 為了避免因404 Not Found而導(dǎo)致大量無(wú)效請(qǐng)求, 我們可以將 404 頁(yè)面優(yōu)化好, 例如在 404 頁(yè)面中加入相應(yīng)得 HTML meta tag , robots noindex , rel="canonical" 等方法來(lái)告訴 Googlebot 這是一個(gè) 404 頁(yè)面, 不必去 indexing .
4. 啟用Gzip壓縮: Gzip 是一個(gè) HTTP 服務(wù)端已集成好得文件壓縮方式, 在 Apache 服務(wù)端上啟用 Gzip 壓縮之后能夠?qū)?HTML/CSS/JS 等文件源代碼大少出 50%~70%, 能夠顯然出劇鳳 HTTP request 次數(shù) .
5. CDN (Content Delivery Network) : CDN(Content Delivery Network) 是一個(gè) web content delivery system （web content delivery system ） ,CDN 最大作用是將 web page content deliver to user with high performance and availability . By using a CDN service , you can reduce the number of requests sent to your server and improve the loading speed of your website .
6. Cache-Control Header : Cache-Control header is an important part of HTTP protocol which helps browsers determine whether or not they should cache certain resources on their local machine for faster access in future visits . By setting appropriate values for this header , you can ensure that browsers will only fetch resources from your server when necessary instead of making unnecessary requests every time a visitor visits your site . This will help reduce the number of requests made to your server and thus improve the overall performance of your website .
7. Minify Resources : Minifying resources such as JavaScript and CSS files is another way to reduce the number of requests made by visitors' browsers when accessing a webpage on your website . By minifying these files , you can remove all unnecessary characters such as whitespace characters and comments which are not required for execution but still take up space in the file size resulting in fewer bytes being transferred over network connections thereby reducing load times significantly .
8. Use Lazy Loading : Lazy loading is a technique used by developers to delay loading certain elements until they are needed by users instead of preloading them at once during initial page load itself thereby reducing total amount data transferred over network connection while improving overall page load times significantly since only essential elements are loaded first while rest get loaded later on demand basis depending upon user interaction with webpage interface components like scrolling down etcetera..
9. Avoid Redirects : Redirects are often used by developers to redirect users from one URL path to another however it comes at cost since each redirect requires additional round trip between browser client & server before actual resource gets served hence it's always recommended that if possible avoid using too many redirects within same domain or subdomain so as minimize extra latency caused due multiple hops involved in process otherwise use 301 permanent redirection whenever possible so that search engine bots know about new location where requested resource has been moved permanently without any further changes required from their end ..
10 Reduce DNS Lookups: DNS lookups involve resolving hostnames into IP addresses which takes some time depending upon various factors like geographical distance between client & name servers etcetera hence its always recommended that wherever possible try minimizing total number DNS lookups performed per page view either by combining multiple domains into single one or hosting static assets onto same domain as main application codebase itself so as keep total count low enough .. 11 Optimize Images: Images play very important role when it comes designing modern websites however they also come with hefty price tag attached i terms increased bandwidth usage due large file sizes associated with them hence its highly recommended optimize images properly before uploading them onto production environment either manually via tools like Photoshop or automatically via online services available out there so as make sure final output looks good enough yet doesn't consume too much bandwidth unnecessarily .. 12 Enable Keep Alive Connections: Keep alive connections allow clients establish persistent TCP connection between themselves & webserver thereby eliminating need establishing separate connection each time new request needs be sent across allowing subsequent ones reuse existing one already established earlier saving precious milliseconds along way thus helping improve overall response times significantly .. 13 Leverage Browser Caching: Browsers usually store copies locally cached versions previously downloaded assets including images scripts stylesheets fonts etcetera order serve them quickly next time around without having re download again provided expiry date set correctly indicating how long particular asset valid after which fresh copy must fetched again from origin source ... 14 Preconnect To Required Origins Early On In Page Load Process Itself Preconnect feature allows clients initiate early handshake process even before actual request gets issued towards target origin thus saving precious milliseconds along way especially useful cases where external origins involved example third party APIs analytics tracking systems social media widgets etcetera ... 15 Use Content Security Policy Properly Content security policy powerful tool hands developers control what kind resources allowed rendered inside browser window based rules defined within policy document itself enabling block malicious scripts injected unknowingly through third parties sources example ads networks affiliate programs etcetera ....
