最近有很多朋友在私聊我，问百度下拉搜索词排名怎么做以及百度下拉框怎么搜索词，这个问题很难吗，我反复的想，我是不是理解错了意思呢，唉!还真就被我找到了，果然有这么回事，那么接下来下编就给大家讲解下，百度的下拉搜索词排名是如何做上去的。

讲到这里可能很多朋友都在想肯定是优化上去的，有这说法的人呢，不能说错也不能说对，究竟是怎么回事了，下面跟随我一起来看看吧

1、百度下拉搜索词的排名原理

百度oq=originalquery原有查询

谷歌oq=相当于百度oq=

搜狗oq=相当于百度oq=

解释输入搜索词，输入了一半，此时选择了下拉框的相关搜索。这输入了一半的词就是originalquery

百度bs=beforesearch上一次搜索词

搜搜bs=等同百度bs

360搜索pq=previousquery等同百度bs

解释2到多次查询的上一次搜索词，伴随bs同时出现的必然有rsv_bp=1，是指2到多次搜索

百度rsv_bp=

解释判断是第几次搜索，常见的有2个值，0和1，默认为0

01次搜索

12到多次搜索

百度f=

解释搜索类型判断，常见的值

1相关搜索

3下拉框搜索

8用户自主搜索

f=12错别字提示正确搜索

百度rsp=relatedsearch?position

解释下拉框相关搜索位置，从0开始，第n+1个相关搜索

譬如搜索“今日头条”，选择下拉框第3个相关搜索"今日头条官网"，rsp=3

2、百度优化下拉搜索词用哪些工具

1)ETable下拉词营销系统。按需优化词，自己充值自己优化，反正是成本低点。效果可以自己把控

2)优化百度下拉词工具 V1.5。上传到网站空间即可使用，新版增加副关键词功能，无需数据库支持，代码纯净无垃圾代码，傻瓜式操作，只需打开网页设置关键词运行程序即可

3、百度下拉框需要用的代码

//init 

var dc2 = null;

var dc3 = null;

var dc4 = null;

var dc5 = null;

var index = 0;

function initDH(targetObjId){

	if(index == 0){

		var arr2 = [];

		dc2 = new dhCombobox();

		dc2.callbackName = "dc2";

		dc2.datasource = arr2;

		dc2.targetObj = document.getElementById(targetObjId);	

		//alert(targetObjId + ' '+document.getElementById(targetObjId));

		//alert(targetObjId);

		dc2.spancont = document.getElementById(targetObjId).parentNode.parentNode;

		//dc2.targetJsVar = targetJsVar;

		dc2.w = 300;

		dc2.h = 300;

		dc2.setup();

		//alert('1111');

		//alert(targetObjId+'1111');

	}

	if(index == 1){

		var arr3 = [];

		dc3 = new dhCombobox();

		dc3.callbackName = "dc3";

		dc3.datasource = arr3;

		dc3.targetObj = document.getElementById(targetObjId);		

		dc3.spancont = document.getElementById(targetObjId).parentNode.parentNode;

		dc3.w = 300;

		dc3.h = 300;

		dc3.setup();

		//alert('2222');

		//alert(targetObjId+'2222');
	}
	if(index == 2){

		var arr4 = [];

		dc4 = new dhCombobox();

		dc4.callbackName = "dc4";

		dc4.datasource = arr4;

		dc4.targetObj = document.getElementById(targetObjId);		

		dc4.spancont = document.getElementById(targetObjId).parentNode.parentNode;

		//dc4.targetJsVar = targetJsVar;

		dc4.w = 300;

		dc4.h = 300;

		dc4.setup();

		//alert('3333');

		//alert(targetObjId+'3333');
	}

	if(index == 3){

		var arr5 = [];

		dc5 = new dhCombobox();

		dc5.callbackName = "dc5";

		dc5.datasource = arr5;

		dc5.targetObj = document.getElementById(targetObjId);		

		dc5.spancont = document.getElementById(targetObjId).parentNode.parentNode;

		//dc5.targetJsVar = targetJsVar;

		dc5.w = 300;

		dc5.h = 300;

		dc5.setup();

		//alert(targetObjId+'4444');

	}else{

		var arr5 = [];

		dc5 = new dhCombobox();

		dc5.callbackName = "dc5";

		dc5.datasource = arr5;

		dc5.targetObj = document.getElementById(targetObjId);
