SEO与SEM之间的转换：如何实现有效的搜索引擎营销策略

import time

from multiprocessing import Pool

模拟官方UA列表

OFFICIAL_UAS = [

Mozilla/5.0 (compatible; Baiduspider/2.0; +)",

Mozilla/5.0 (compatible; Googlebot/2.1; +)",

360Spider

class SpiderSimulator:

def __init__(self, target_urls):

self.target_urls = target_urls

def simulate_crawl(self, url):

模拟单次爬取行为

ua = random.choice(OFFICIAL_UAS)

print(f"[{time.strftime('%Y-%m-%d %H:%M:%S')}] 使用UA {ua} 访问 {url}")

实际应包含请求间隔控制、代理IP轮换等逻辑

time.sleep(random.uniform(0.5, 2.0))

return True

if __name__ == '__main__':

示例URL列表（实际应从数据库或文件读取）

urls = [

pool = Pool(processes=3) 并发控制

simulator = SpiderSimulator(urls)

pool.map(simulator.simulate_crawl, urls)
