多媒體文件如Flash、JavaScript 等都是不利于 SEO 的因子之一. Flash 無法直接讀取文字信息:一、引言

網(wǎng)站優(yōu)化是指通過各種方法來提高網(wǎng)站的可訪問性和用戶體驗，從而使其在搜索引擎中有較好的表現(xiàn)。然而，隨著互聯(lián)網(wǎng)的發(fā)展，不少人利用各種手段來誤導流量并濫用SEO優(yōu)化工具；此外，也存在一些“七大陷阱”——即七大常見的蛛形物體。因此，要想實施有效的SEO優(yōu)化工作，必須避免這些“七大陷坑”。

二、七大常見的蛛形物體

1. 廣告代理: 這是一個很常見的問題, 廣告代理將根據(jù)客戶要求, 把廣告內(nèi)容加到相應的web 頁上, 甚至可能出現(xiàn)在原始內(nèi)容之前. 雖然這樣能夠保證廣告顯眼, 但也會造成無意義冗余信息, 如此便無法使得web 頁有效地表明原始內(nèi)容.

2. 多媒體文件: 多媒體文件如Flash、JavaScript 等都是不利于 SEO 的因子之一. Flash 無法直接讀取文字信息; JavaScript 本來就是動態(tài)生成 HTML 頁面, 沒有固定風格; 而 Java Applet 則不能夠直接顯示出來. 三者都無法使得 web 頁中出現(xiàn)重要關鍵字信息.

3. Meta Tag: Meta Tag 是 HTML/XHTML 等 Web Markup Language (WML) 中所使用到的 meta-information tag , 如 title tag , description tag , keyword tag . 雖然 meta-information tags 本來就是 SEO 的重要工具之一, 但如今卻有人將 meta-information tags 濫用作為 spamming tool .

4. Robots Exclusion Protocol (REP): REP 是 robots exclusion protocol 的畫龍閣般(robots txt) , robots txt file is a text file that contains instructions for search engine spiders on how to crawl and index the website's content . It can be used to block certain pages from being indexed by search engines or even prevent them from crawling the entire site altogether . However , if not properly configured it can lead to serious problems with your website's visibility in search engine results pages (SERPs).

5. Cloaking : Cloaking is a technique used by some websites to present different content or URLs to human users and search engines . This practice is considered unethical as it attempts to deceive both users and search engines into believing that they are viewing different content than what actually exists on the page . As such , cloaking should be avoided at all costs when optimizing a website for better rankings in SERPs . 6 Link Farms : Link farms are networks of websites created solely for the purpose of exchanging links between each other in order to artificially inflate their link popularity scores within major search engines like Google and Yahoo! While this may seem like an effective way of increasing your website's visibility in SERPs initially , it will eventually result in severe penalties imposed by these same search engines once they detect such activities taking place on your site . 7 Doorway Pages : Doorway pages are webpages designed specifically for ranking high within SERPs but which offer little value or relevance once visitors arrive at them from those same searches . These types of pages often contain hidden text or links which direct visitors away from the doorway page towards another destination without their knowledge ; thus making them highly ineffective as far as providing any real benefit goes when attempting SEO optimization efforts on a given website
