Frequently Asked Questions
Why do legacy ping networks like Indexsor struggle with modern Google indexing?
Legacy tools like Indexsor traditionally relied on sending XML-RPC ping signals, RSS aggregator pings, and basic webhooks to alert search engines. While this worked over a decade ago, Google's modern crawler infrastructure heavily discounts or completely ignores third-party pings to prevent spam. IndexFlow instead utilizes official Google Indexing API channels, IndexNow protocols, and high-authority contextual crawl networks that prompt direct Googlebot and Bingbot crawls within minutes.
How does IndexFlow's pre-submission index check save credits compared to Indexsor?
With Indexsor and standard indexing tools, submitted URLs consume credits immediately upon entry—even if Google already indexed some of those pages organically. IndexFlow performs real-time pre-submission verification against Google's live index. If a URL is already indexed, the credit is immediately refunded back to your account balance. You only pay for URLs that actually require indexing.
Can IndexFlow index both owned websites and off-page backlinks?
Yes. IndexFlow is a universal indexing platform. For owned domains, you can connect your Google Search Console to automate new posts, product updates, and fixes for 'Discovered - currently not indexed'. For off-page campaigns (guest posts, digital PR, niche edits, Web 2.0s, citations, and Tier 2 links), IndexFlow submits URLs without requiring domain ownership or DNS verification.
Does IndexFlow monitor submitted URLs for de-indexing after Google core updates?
Yes. Algorithmic core updates regularly cause newly indexed pages or tier-2 backlinks to fall out of the index. IndexFlow includes automated 24/7 de-index monitoring. If our system detects that a previously indexed URL has dropped from the SERPs, it automatically queues a re-submission to recover indexation without manual intervention.
How does pricing compare between Indexsor and IndexFlow?
Indexsor requires monthly subscriptions or rigid credit packages with no free tier. IndexFlow provides a 100% free plan giving 100 free indexing credits every single month forever, no credit card required. Paid plans start at just $12/month with rollover credits, REST API access, webhooks, and volume discounts.
Does IndexFlow provide a developer API for bulk automated indexing?
Yes. IndexFlow features a full REST API with webhooks, CSV batch uploads, and detailed documentation. Developers and agencies can integrate indexing directly into CMS workflows, programmatic SEO pipelines, or backlink building scripts.
