Indexing services like IndexMeNow or IndexChex don’t directly “force” Google to index pages, and they’re not just simple backlink builders either.
What they usually do is create signals that help discovery—like temporary backlinks, pinging systems, RSS feeds, redirects, or API-based submissions (mainly for Bing). These give search engines new paths to find your URL faster.
So yes, some backlinks may be involved, but they’re typically low-quality and short-lived. The real goal is speeding up crawling, not passing ranking power.
That said, if a page isn’t index-worthy (thin content, low value, duplicate), no indexer will make it stick. Indexing still depends mostly on content quality, site authority, and internal linking.
