Brand promotion: this article introduces Guangsuan's GSI indexing service and GPC crawler pool. It is a vendor-introduction piece, not an independent review or a commissioned evaluation.
"We published the page three weeks ago and it still doesn't show up." That sentence usually starts a search for an indexing service. Before you buy one, it helps to know what the service actually does, what it cannot do, and what you should have ready before the first conversation.
The short answer
A Google indexing service is a crawl-promotion service. It works on the discovery and crawling side of the process: getting a URL in front of Googlebot so the page has a chance to be read. It does not decide whether the page enters the index, and it does not produce rankings.
Guangsuan describes its own service this way. GSI (Google Speed Indexing) is Guangsuan's service name, not a Google product, and the company states that the service works on discovery and crawling opportunities while the indexing decision remains Google's. The same page puts the boundary in one line: submitting a URL is not the same as being indexed, and being indexed is not the same as ranking.
That distinction is the whole reason this article exists. If you expect an indexing service to guarantee that a page appears in search results, you will be disappointed. If you understand it as removing a discovery obstacle, you can judge it on evidence.
What the service actually does
The published process has three visible stages, and only the first two are the service's job.
- Discover the URL. The page is placed where it has a chance of entering Google's crawl queue.
- Crawl the page. Googlebot visits and reads the content.
- Index judgment. Google decides whether the page enters the index. This stage is not controlled by the service.
Guangsuan's GSI page describes the crawl-side work as running through its own GPC crawler resource pool and related link structures, applied to the URLs you submit. The company also states plainly that the service cannot bypass Google's quality judgment and does not replace content or technical fixes.
Verification is part of the published method rather than an afterthought. Guangsuan's GPC page lists three separate layers to look at: the resource dashboard for pool activity, your own server logs to confirm genuine Googlebot requests by URL, time and response status, and Google Search Console to observe the final indexing state. The page states that these three data sets cannot substitute for one another, and that pool totals should not be converted into a target site's Googlebot visits or indexed pages.
What it does not do
Three limits are stated on Guangsuan's own pages and are worth repeating, because they are the parts buyers tend to assume away.
- It does not guarantee indexing. Whether, when and for how long a page is indexed is Google's decision. Guangsuan states that URLs can also leave the index later because of content quality, duplicate pages, canonical choices, access status or Google's own reassessment.
- It does not produce rankings. A page that is indexed but has no keyword ranking is a ranking and competitiveness question, not an indexing question. Guangsuan's GSI page separates that case explicitly.
- It does not repair the page. If a URL is blocked from crawling, carries a noindex directive, redirects, or duplicates another page, that has to be checked and fixed first. Guangsuan lists those conditions as things to verify before submitting a URL.
There is also a policy boundary. Guangsuan states that crawl guidance and any link operations involved must comply with Google's spam policies, and that no SEO operation can be promised as 100% risk-free.
Who it suits, and who it does not
The service fits a specific situation: the pages are accessible, the content is in place, and the problem is that Google has not been reading them.
Guangsuan's GPC page describes three situations it is aimed at — a new site whose pages are live but rarely show crawl records, a site with many pages where important URLs are waiting to be discovered, and published backlink pages that have not been picked up. In each case the first step is to check the crawl entry point, not to buy volume.
It is a poor fit when the real problem is elsewhere. If Google has already crawled the page and declined to index it, adding crawl pressure does not address the reason. If the page is indexed but not ranking, that is a different problem again. Guangsuan's own guidance is to work out which step you are stuck on before choosing a service.
What to prepare before you ask for one
This is the part that decides whether the first conversation is useful. Guangsuan's GPC page asks for a URL sample, the number of pages to be handled, and log or Search Console data before a configuration is chosen. Prepare the following.
1. A clean URL list
Final URLs only — the address that actually returns the page, not a redirect source. State the protocol, host and path exactly. Group the list by page type (homepage, category, product, article, external page) so the provider can see what is being submitted.
2. The current status of each group
For each group, record what Search Console currently reports. Guangsuan's GSI page separates three states and treats them differently: discovered but not yet crawled, crawled but not indexed, and indexed but without keyword rankings. Knowing which group you are in changes the recommendation.
3. Evidence you can hand over
Server log extracts showing Googlebot requests, if you have them, and the relevant Search Console reports. Guangsuan's GPC page describes log verification as part of how the work is checked, so having the baseline before you start is what makes a later comparison meaningful.
4. Page volume and priority
How many URLs in total, and which ones matter most. Guangsuan's GPC page makes a point that is easy to skip: uploading fewer URLs concentrates the resources, so priority order matters more than raw volume.
5. The verification method, agreed in advance
Decide before you start how progress will be judged. Guangsuan's GSI page states that the service scope, observation window, verification method and reporting are confirmed before cooperation, and that with site access you should use Search Console's URL inspection and page indexing report rather than a site: query, which does not list every indexed URL.
How Guangsuan's service is structured
Guangsuan publishes two related routes, and they are not the same product.
GSI indexing service is a per-URL engagement, priced by the size of the URL batch. The published tiers run from 100 URLs up to 100,000 or more, with reference observation periods that lengthen with batch size. Guangsuan labels the published indexing-rate range as a reference interval, not a per-batch commitment, and states that actual timing depends on page quality, site status and Google's processing.
GPC crawler pool is a monthly dedicated-resource rental with its own dashboard, where you upload URLs yourself. Guangsuan states that the published pool figures are nominal package configurations rather than monitored measurements, and that the counting rules for pool totals and forced-crawl figures should be confirmed against a dashboard sample and written into the contract before purchase.
Guangsuan notes that the two can be chosen according to need and do not have to be bought together. If you want to see how the scope, tiers and verification terms are described, the GSI indexing service page lays them out, and the GPC crawler pool page covers the resource-rental route.
FAQ
Is GSI a Google product?
No. Guangsuan states that GSI (Google Speed Indexing) is its own service name and does not represent a Google product, an official partnership or a priority indexing channel.
Will an indexing service get my page into Google?
It can improve the chance that a page is discovered and crawled. Whether it is indexed, when, and whether it stays indexed is decided by Google. Guangsuan states this limit on its own service page.
Can I submit pages I do not own?
Guangsuan's page says external pages can be discussed if you have authorisation to operate on them, and that the URL must be accessible and free of obvious crawl blocks, noindex directives or duplicate-canonical problems.
How do I check whether it worked?
Use Search Console with site access — the URL inspection tool and the page indexing report. Guangsuan's page notes that a site: query is not a reliable index count, and that for third-party pages without Search Console access the verification method needs to be agreed in advance.
None of this guarantees a result, and no provider can promise one. What it gives you is a clearer question to ask, a list to prepare, and a way to tell a crawl problem from a content problem before you spend anything.
