网站收录异常诊断：为什么Google不索引你的页面

我们站有2000个产品页Google只索引了800个。排查原因的过程很痛苦。后来我用搜索API爬虫做了系统性的诊断找出了所有问题。这篇文章分享诊断清单。一、索引问题诊断流程defdiagnose_indexation_issues(domain:str,sitemap_urls:List[str],api_key:str)-Dict:诊断索引问题issues[]# 1. 检查robots.txtrobots_issuescheck_robots_txt(domain)issues.extend(robots_issues)# 2. 检查meta robotsmeta_issuescheck_meta_robots(sitemap_urls)issues.extend(meta_issues)# 3. 检查canonicalcanonical_issuescheck_canonical_tags(sitemap_urls)issues.extend(canonical_issues)# 4. 检查索引状态index_issuescheck_indexation_status(domain,sitemap_urls,api_key)issues.extend(index_issues)# 5. 检查404error_issuescheck_404_errors(sitemap_urls)issues.extend(error_issues)# 6. 检查重复内容duplicate_issuescheck_duplicate_content(sitemap_urls)issues.extend(duplicate_issues)return{total_pages:len(sitemap_urls),issues_found:len(issues),issues_by_severity:{critical:len([iforiinissuesifi[severity]critical]),high:len([iforiinissuesifi[severity]high]),medium:len([iforiinissuesifi[severity]medium])},issues:issues}defcheck_indexation_status(domain:str,urls:List[str],api_key:str)-List[Dict]:检查页面索引状态issues[]# 批量检查forurlinurls[:100]:# 限制数量page_nameurl.split(/)[-1]if/inurlelseurl headers{X-API-Key:api_key,Content-Type:application/json}body{q:fsite:{domain}inurl:{page_name},hl:en,gl:us,page:1}try:rrequests.post(https://api.serpbase.dev/google/search,headersheaders,jsonbody,timeout30)datar.json()indexedany(urlinitem.get(link,)foritemindata.get(organic,[]))ifnotindexed:issues.append({url:url,issue:not_indexed,severity:high,recommendation:Check for noindex, robots.txt block, or canonical issues})except:passreturnissues二、常见索引问题问题占比解决方案Meta noindex25%移除noindex标签Robots.txt阻止20%更新robots.txt404错误15%修复或301Canonical错误12%修复canonical重复内容10%合并或canonical页面质量低8%提升内容质量内链不足5%增加内链其他5%具体分析三、索引恢复方案defgenerate_index_recovery_plan(issues:List[Dict])-List[Dict]:生成索引恢复计划plan[]# 按优先级排序critical[iforiinissuesifi[severity]critical]high[iforiinissuesifi[severity]high]forissueincriticalhigh:ifissue[issue]not_indexed:plan.append({url:issue[url],action:submit_to_gsc,timeline:immediate})elifissue[issue]meta_noindex:plan.append({url:issue[url],action:remove_noindex,timeline:immediate})elifissue[issue]robots_blocked:plan.append({url:issue[url],action:update_robots,timeline:1 day})returnplan索引问题诊断是最基础但也最重要的SEO工作。如果页面不被索引再好的内容和外链都没用。建议每月做一次全站索引检查用搜索API比site:查询更可靠。
