一、爬虫基础

掌握爬虫手艺是SEO干活的关键一环。本文将分享怎么用Python编写高大效爬虫代码，帮您飞迅速获取所需数据。

二、 Python爬虫实例

import requests
url = "http://example.com"
response = requests.get
html_content = response.text
print
    

三、爬取长远尾关键词

长远尾关键词对于SEO至关关键。以下代码展示怎么用Python爬取百度贴吧的图片。

import requests
from bs4 import BeautifulSoup
url = "https://tieba.baidu.com/f?kw=Python"
response = requests.get
soup = BeautifulSoup
images = soup.find_all
for img in images:
    print
    

四、许多线程爬取

用许多线程能搞优良爬虫效率。以下示例展示了怎么用Python许多线程爬取帖子列表。

import requests
from bs4 import BeautifulSoup
from threading import Thread
def fetch:
    response = requests.get
    soup = BeautifulSoup
    threads = soup.find_all
    for thread in threads:
        print
url = "https://www.example.com/forum.php"
Thread).start
    

五、 爬虫代码用说明

# 爬虫代码用说明.txt
1. 安装Python周围
2. 导入所需库
3. 配置爬虫参数
4. 运行爬虫
5. 查看后来啊
    

六、 SEO指标抓取

爬虫不仅能抓取网页内容，还能抓取SEO指标，如长远尾词数量、收录数和优化困难度等。

import requests
from bs4 import BeautifulSoup
url = "http://example.com"
response = requests.get
soup = BeautifulSoup
long_tail_keywords = soup.find_all
for keyword in long_tail_keywords:
    print
