某建材公司电子商务网站主要完成网上直销、产品宣传、技术咨询、信息收集和客户管理等工作。网站管理小组一方面负责网站推广、信息发布和信息采集,另一方面负责网站的管理和维护。

公司网站推广碰到一些问题,网站管理小组发现在搜索引擎中公司网站的排名靠后。公司要求对网页进行优化,以提高网站在搜索引擎列表中的排名。请叙述如何对网页进行优化(不超过300字)。

答案

参考答案:对网页优化的关键是
·网页标题中使用关键词;
·元标记中使用关键词;
·提高关键词在网页中出现的频率;
·使用隐藏的图形文档,在图形中使州<ALT=“关键词”>;
·创建链接活动,提高网站在搜索引擎的排名

解析:利用搜索引擎是推广网站的重要手段。当用户以关键词查找信息时,搜索引擎会在数据库中进行搜寻,如果找到与用户要求内容相符的网站,便采用特殊的算法。通常根据网页中关键词的匹配程度,出现的位置/频次,链接质量等;计算出各网页的相关度及排名等级,然后根据关联度高低,按顺序将这些网页链接返回给用户。根据搜索引擎的工作原理,优化网页可以提高网站在不同搜索引擎中的排名。提高网站在搜索引擎列表上位次的主要技术包括(但不限于):
·在标题中使用关键词。在HTML的<title></title>标记中使用合理的关键词对网站提高在搜索列表中的位置是非常重要的。因为若此类关键词与待搜索的内容吻合,则该网站就比那些只是在网页文本中出现关键词的网站的排名位置靠前。
·在元标记中使用关键词。标记<meta>中含有的关键词虽然用户看不见,但是却能够被搜索引擎用来编辑索引。对大多数搜索引擎而言,若用户输入的关键词与某网站的元标记正好吻合,则该网站在搜索列表中的排名就比那些没有使用元标记的网站靠前。
·提高关键词出现的频率。提高关键词在网页中出现的频率,也能提高网站在搜索列表中的排名。
·在隐藏的图形文档中使用关键词。大量使用图形文档不利于网站在搜索列表中的排名,在必须使用的图形文档中利用<ALT=“关键词”>添加隐藏的图形文档有利于提高网站在搜索列表中的排名。
·创建链接活动。搜索引擎的自动信息搜集功能主要分为两种:①是定期搜索;②是提交网站搜索。目前最好的办法是创建链接活动以获得更多的外部链接。这样一方面让搜索引擎有更多机会找到网站并收录,另一方面可以提高网站在搜索列表中的位置。

Barbara hid her jewelry when she went on vacation. When she came back, she couldn't remember where she'd put it.

__小题2:__ Most people have. But memory can be developed.

First, relax. If you're overanxious about remembering something, you'll forget it._ 小题3:__ Take a deep breath and tell yourself that you have all the time in the world to remember.

Second, avoid being negative. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won't remember things. When you forget something, don't say, “Gee, I need to have my brain rewired(重装电线).”

To improve your memory, you'll need to take an active role. Like your body, your memory can be strengthened through exercise.__ 小题4:__ For example, if you're learning a language, try to actively remember irregular verbs.

You may also want to make associations, or links, between what you're trying to remember and things you already know. For example, if you need to catch a plane at 2:00 p.m., you can imagine a plane in your mind and notice that it has two wings.__ 小题5:_
