1. 继续对首页进行调整，围绕 Title 跟 Description

• 首页标题和描述

<title>Phone Number Generator,China,India,US,Indonesia,Brazil,Pakistan,Nigeria,Bangladesh,Russia,Japan</title>

<meta name="description" content="Easily generate phone numbers for top countries like China,India,US,Indonesia,Brazil,Pakistan,Nigeria,Bangladesh,Russia,Japan.Phone Number Generator, Perfect for testing, verification, and various applications.">

• 首页h1的a标签增加title

<h1 class="logo"> <a href="./" title="Phone Number Generator">Phone Number Generator</a></h1>

• 导航栏的a标签增加title

<div class="country-list">    <a class="curr" href="./" title="Phone Number Generator">Home</a>    
<a href="./china-phone-number-generator.html" title="China Phone Number Generator">China</a>    
<a href="./india-phone-number-generator.html" title="India Phone Number Generator">India</a>
<!--此处限于篇幅只列出2个国家，实际页面要把所有10个国家都列出--></div>

• 每一个h2的a标签也增加title

<section>    
<h2><a href="./china-phone-number-generator.html" title="China Phone Number Generator">China Phone Number Generator</a></h2>    
<p>Generate valid China phone numbers with our tool. Perfect for various applications and tests.</p>    
<a href="./china-phone-number-generator.html" title="Generate China Phone Number">        
<button>Generate China Phone Number</button></a>
</section>

于是首页就给每个国家的内页都增加了2个链接——分别传递了“xxx Phone Number Generator”、“Generate xxx Phone Number”两个关键词的权重到对应的国家内页。

2.优化内页
