What caused indexed pages to disappear: A SEO checklist for problems with
indexed pages

1. A page can disappear if Google finds something wrong with that page we discussed about this on page specific Google penalty here.
2. A page can disappear when suddenly it attracts 1000s of backlinks. This might suddenly trigger a filter with Search engine algorithms and that page might go through a strong search engine spam filter and once it clears it will be available again.
3. If a page has any server related problems and not accessible by search engines it will disappear from search engine index
4. If a page has problems with the html or dynamic code and again not properly rendering for the search engines it will be booted temporarily from the index.
5. If a page has hidden links and if detected by spam detecting Googlebot it will assigned a temporary penalty and will be booted from the index.
6. Manual review by certain search engines have made pages disappear. This is though very rare but it does happen and search engines do this to make sure users are not led to the wrong page.
