視頻優化
視頻優化
對視徠頻的搜索引擎優化是這個領域最令人激動的挑戰之一,因為google最近開始在常規搜索結果中給與視頻更高的突出度。想要做好非常的簡單,很多時候只需要靈活擴展一下你剛剛學到的關於Microsoft 0frice和PDF文件的優化原則就好了。
首先,需要適當地準備一下視頻文件。在Windows Explorer中找到視頻文件,並確定該文件不是只讀的,然後右擊視頻的圖標來進入屬性設置。通過使用連接符,將文件重命名為關鍵字豐富的模樣(例如[Ibusiness-Calds-from-chambers.avi)。接下來,再次右擊進入“summary”標籤,給文件添加一個關鍵字豐富的標題(例如Business Cards fromChambers Print)並添加一些關鍵字。
Google Video支持上載.avi、mpg、Quicktime和Windows媒體文件(幾乎支持各種擴展名)。幀速應大於12幀每秒,而比率應該大於260kbps。Google會將視頻剪裁成4:3並通過Macromedia Flash以320×240的解析度顯示。因此,如果你從頭製作視頻的時候,最好使用4:3的縱橫比來避免“letterbox”剪裁問題。
有兩種方法可以上載視頻到Google Video。如果你的視頻文件小於100MB,上載視頻最簡單快捷的方法就是使用Google基於web的上載器。如果視頻大於100MB,或者你希望一次上載多個視頻的話,Google Videouploader客戶端軟體就是你最好的選擇了。另外作為粗略的建議,將視頻控制在4.5分鐘一下會讓這個過程舒服的多。
如果你通過基於Web的介面上傳,你可以設定標題、描述、類型和文件的語種。對於title域來說,只需要使用你在文件屬性對話框中使用的標題就好了(也可以更長一點兒)。
而描述的話,和我們在:meta-description標籤一節中的原則相同。選擇一個適合的類型(例如“business”),設置成公共可見,然後點擊上載視頻即可。一旦你的視頻上載到Google(或者YourTube),你就可以獲得能夠將視頻插入網頁中的代碼了,這意味這Google將會幫你託管和服務視頻文件(節省你的計算資源和帶寬費用)。
Video search engine optimization is the most exciting in this area one of the challenges, because Google has recently started to give the regular search results, video highlights higher degree. Want to do is very simple, often only need to be flexible about your extension just learned about Microsoft 0frice optimization principles and PDF files just fine.
First, the need to properly prepare your video files. In Windows Explorer, locate the video file, and determine that the file is not read-only, then right-click the video icon to enter the property. Through the use of connectors, will rename the file to look like keyword rich (for example, female [Ibusiness-Calds-from-chambers.avi). Next, right-click again into the "summary" tab, add a keyword rich to file the title (such as Business Cards fromChambers Print) and add some keywords.
G徠oogle Video support on the set. Avi, mpg, Quicktime and Windows Media files (almost support a variety of extension). Frame rate should be greater than 12 frames per second, while the ratio should be greater than 260kbps. Google Video will be cut to 4:3 by Macromedia Flash to 320 × 240 resolution display. Therefore, if you scratch that video, the best to use a 4:3 aspect ratio to avoid the "letterbox" cut problem.
There are two ways to upload video to Google Video. If your video file smaller than 100MB, upload the video the most simplest and quickest way is to use the Google web-based uploader. If the video is larger than 100MB, or more than you want to upload a video of it, Google Videouploader client software is your best choice. In addition, as a rough proposal, the video control in 4.5 minutes what would make the process more comfortable.
If you have Web-based interface to upload, you can set the title, description, type and file of language. For the title field, the only file you need to use the title of the Properties DIALOG box like the (also a little longer).
The description of the case, and we have: meta-description tag section of the same principle. Select a suitable type (such as "business"), set the public can see, then click on the video can be uploaded. Once your video uploaded to Google (or YourTube), you can get the video into web page code, this means that Google will help you host and service video files (save your computing resources and bandwidth costs).
案例通過使FLASH與XML完美結合,即保持了視頻的功能,同時為視頻外觀增加了FLASH式的便捷與美感。其中,Xml用標記對語言方式記錄數據,通俗易懂,flash用函數將其調入解柝並完成很多動態功能,修改時只需改外部xml文件就能達到修改flash內容的目的,方便。在SEO中,運用 Xml 製作視頻頁面,比較一般的視頻網頁,更利於搜索引擎的信息抓取與收錄。
Flash+XML的運用前景
XML 當初就是為不同平台間的數據交換設計的,在各種不同的環境中都能穩定的運行,並且執行效率高。那麼就可以設計這樣的模型:Flash直接從XML中載入數據使用,對與不同的平台和使用環境,用相關的伺服器腳本對XML做數據操作,將XML當做資料庫使用。這樣的好處有兩個:一是直接讀取XML時不用進行中間環節的數據存取過程(相對於Flash讀取伺服器腳本再讀取資料庫),況且Flash讀取XML效率本來就很高,用戶在訪問網頁的時候速度就會很快;二是XML是為跨平台使用設計的,程序可移植性好,在不同的平台間使用,只需要更換相關的伺服器腳本程序就可以了。
從以上分析中了解到,Flash+XML除了在視頻製作中有很好的發展空間外,在中小規模的Flash後台技術使用時,Flash+XML將是最適合的解決方案。
