Indexed in minutes to hours,not weeks.

When you build a backlink, Google doesn't always discover and index it right away. An un-indexed backlink carries almost no SEO value. An indexing service speeds up that process so your backlinks start working far sooner than waiting for organic crawling.

Yes. We don't use spam links, PBNs or blackhat tools. We simply help Googlebot discover your URLs faster — fully in line with Google's own guidance (Google itself encourages submitting URLs via GSC/sitemap).

No. VoIndex works independently of GSC. That's also why you can index backlinks on sites you don't own — something GSC can't do.

The average index rate across the system is around 87%, depending on URL and destination-page quality. You can always see the real success rate for each job on the dashboard. We don't promise 100% because the final indexing decision belongs to Google.

After 48h the system checks indexing automatically and diagnoses every un-indexed link. Common causes: noindex tags, robots.txt blocks, 404 errors, broken redirects, or low-quality destination pages. The report flags each case so you can fix it. Credit is charged per submission and is non-refundable, so it's worth checking your URLs before submitting large batches.

Any public URL returning a 200 status: backlinks, guest posts, tier-2/3 links, profiles, social, web 2.0, forums, entities, 301 redirects, product pages, blog posts and more. URLs with noindex, robots.txt blocks or 404 errors can't be indexed.

Processing starts within minutes of submission. Most indexing results appear within the first few days; you can track progress in real time and get an email when the job completes.

No limit — as long as you have enough credit. Paste hundreds of URLs in one submission; the system processes them in parallel and reports combined progress.

PayPal (card or PayPal balance), billed in USD. Customers in Vietnam can also pay by Vietnamese bank transfer via PayOS. Credit is added automatically and never expires.

Google AI Overviews, AI Mode and Gemini only cite pages that Google has indexed. Brand mentions, PR, guest posts and reviews that aren't indexed can't be used as sources by AI. VoIndex pushes these URLs into the index and reports which ones are eligible.

No. Indexing is a prerequisite. AI also picks sources based on content quality, relevance and trust. VoIndex handles the "can AI see the page" part, not the citation itself.

Not directly. ChatGPT search relies mainly on Bing's index, while VoIndex currently focuses on Google indexing. For ChatGPT, submit your own website's URLs through Bing Webmaster Tools.
