Drip-feed indexing

Definition

Drip-feed indexing is a submission schedule. A user hands an indexing service a batch of URLs and a duration, and the service releases the URLs in portions across that duration rather than all at once. A 3,000-URL batch dripped over 30 days becomes roughly 100 URLs a day.

The technique is offered by most paid backlink indexers as an option on top of their standard mode. It sits beside the speed tiers described in standard vs instant indexing: those decide how hard each URL is pushed, while drip feed decides when each URL is pushed.

Why link builders use it

Backlinks earned through ordinary publicity arrive unevenly but gradually: a few mentions, then a few more. A campaign that produces hundreds of guest posts, citations or profiles in a week and then pushes all of them into Google's discovery pipeline on the same day creates a sharp spike in newly found links.

Practitioners worry that such spikes draw attention. Google's spam policies treat link schemes as manipulation, including "using automated programs or services to create links to your site," but Google has not published a rule about link velocity as such. Drip feeding is therefore a precaution based on industry practice, not a documented Google requirement. It changes how fast links are discovered; it does not change whether a link is compliant.

Other reasons to drip:

• Client reporting. Agencies often prefer steady weekly gains over a single jump followed by nothing.
• Tiered campaigns. Second-tier links pointing at first-tier pages are commonly spread out so the first tier gets crawled before the links pointing at it.
• Large batches. A batch larger than a standard job's limit can be scheduled in one go.

Choosing a schedule

These are conventions rather than rules. The useful question is how long the links would plausibly have taken to appear if earned one at a time. Pages that are already indexed, or that sit on large sites Google crawls constantly, gain little from dripping because Google will find them quickly anyway.

What drip feeding cannot fix

Spreading submissions over time does nothing for a page that Google would not index in the first place. Thin pages, duplicated directory listings, pages blocked by robots.txt or carrying noindex, and links that have already been removed (link rot) fail the same way at day 1 or day 30. The common causes are listed in why backlinks don't get indexed.

It also lengthens the time before the full set can be evaluated. If a drip runs 30 days and indexing usually settles a few days after submission, the last URLs in the batch cannot be judged until more than a month after the job started.

Drip feed at IndexChex

IndexChex, which publishes this wiki, offers drip feed as a variant of standard submission:

• Duration from 1 to 30 days.
• Up to 25,000 URLs per drip job, compared with 10,000 for an ordinary standard job.
• The same per-URL credit cost as standard.
• A drip job cannot also carry an automatic scheduled re-check; the check is run separately after the drip completes.

Mechanically, each released portion is handled the same way as a standard submission, following the process outlined in how backlink indexers work.

Checking a drip-fed batch

Because URLs are released over weeks, checking a drip-fed batch once at the end gives an incomplete picture of the early portions and a premature one of the last. A workable pattern is to check in two passes: once at the midpoint for the first half, and once about five days after the drip ends for the rest. Methods and pitfalls are covered in verifying backlink indexation.
