AI Link building agency placement QA — Above/below fold, context, outbound neighbors.

In the intricate machinery of SEO (keresőoptimalizálás), securing a placement is often treated as the finish line. The outreach team finds a prospect, negotiates a price or trade, and the content is published. The client receives a report with a URL, and everyone celebrates.

However, for a high-performance AI link building agency, the publication of the link is not the end—it is the beginning of the most critical phase: Placement Quality Assurance (QA).

Not all backlinks are created equal, even if they come from the same domain. A link buried in the footer of a "Domain Rating 70" site is worth significantly less than a link in the introductory paragraph of a "Domain Rating 30" site. As Google’s algorithms move towards the "Reasonable Surfer Model"—which attempts to mimic human behavior—the position, context, and neighborhood of a link determine its actual ranking power.

This article details the rigorous QA protocols necessary to evaluate link placements, ensuring that every backlink passes the "human value" test that modern search engines demand.

Part 1: The "Reasonable Surfer" and Visual Placement

To understand why placement QA matters, we must revisit Google’s shift from the "Random Surfer" model (PageRank) to the "Reasonable Surfer" model.

In the early days, a link was a link. If it was on the page, it passed value. Today, Google assigns different weights to links based on the likelihood that a user will actually click them. This brings us to the most debated metric in placement QA: The Fold.

1. Above the Fold vs. Below the Fold

"Above the fold" refers to the portion of a webpage that is visible without scrolling.

• The Premium Zone: Links placed in the first 200-300 words of an article (usually above the fold on desktop) carry the most weight. They signal to Google that this reference is central to the topic, not an afterthought.

• The Drop-Off: As you scroll down, the probability of a user clicking a link decreases. Consequently, the equity (PageRank) passed by that link diminishes.

• The Footer/Sidebar Trap: Links placed in sidebars or footers are often devalued or ignored entirely by Google, as they are viewed as "boilerplate" or navigational rather than editorial.

The AI QA Solution: Human eyes are subjective. AI tools use "headless browsers" (simulating a Chrome browser without a GUI) to render the page and mathematically calculate the pixel position of the link.

• QA Check: Is the link within the first 1080px of the vertical height?

• QA Check: Is the link obscured by pop-ups or aggressive ads?

2. The "buried" Link

A common tactic by low-quality link sellers is to place guest posts correctly, but then bury the link in a "Recommended Reading" section at the very bottom of the article.

• The Risk: These sections are often generated dynamically or look like ads.

• The Agency Standard: A link must appear within the body content (the main editorial flow). It should be wrapped in <p> tags, not <div> or <li> tags associated with lists or widgets.

Part 2: Contextual Relevance – The Semantic Bridge

Once we confirm the link is visible, we must analyze its context. In the era of Semantic Search and AI Overviews, context is king. A link is a bridge between two documents. If the bridge doesn't make sense, the traveler (Googlebot) won't cross it.

1. Semantic Distance

This is where AI truly shines in SEO (keresőoptimalizálás). We are no longer just looking at "exact match keywords." We are analyzing the vector space of the surrounding text.

• The Scenario: You are building a link for a "CRM Software" product.

• Bad Context: The article is about "Top 10 Office Chairs." The sentence reads: "While sitting in your chair, you might use [CRM Software] to do work."

  • Verdict: This is forced. The semantic distance between "Office Chairs" and "CRM" is too wide. Google sees this as unnatural.

• Good Context: The article is about "Sales Productivity Tools." The sentence reads: "To manage leads effectively, sales teams rely on [CRM Software] to automate follow-ups."

  • Verdict: High relevance. The surrounding entities ("sales," "leads," "manage") support the link.

2. The "Sentence-Level" QA

Agencies must audit the sentence containing the link.

• Grammar and Flow: Does the link break the sentence? (e.g., "You should buy [best running shoes] today.") This looks like spam.

• The "Commercial Interrupt": Is the tone of the article informational, but the sentence with the link suddenly becomes aggressively salesy? This "tonal shift" is a flag for paid manipulation.

3. Anchor Text Distribution

Placement QA also involves checking the anchor text against the client's current profile.

• Over-optimization: If the client already has 50 links with the anchor "Buy Cheap Laptops," and the new placement also uses "Buy Cheap Laptops," the QA team must reject it.

• The Fix: Change the anchor to something more natural, like "this range of affordable computers" or "brand name options."

Part 3: Outbound Neighbors – Who Else is Invited?

You are judged by the company you keep. This is the "Bad Neighborhood" principle. Even if the website has a high DR, the specific page where your link lives might be toxic if it links to spam.

1. Co-Citation Analysis

When Google crawls a page, it looks at all the outbound links to understand the topic.

• The Scenario: Your link points to a legitimate Finance website.

• The Neighbors: On the same page, there are links to:

  1. A dubious Crypto gambling site.

  2. An essay writing service.

  3. A "male enhancement" pill site.

• The Result: Google groups your Finance site with these spam categories. Your site effectively gets "infected" by the bad neighborhood.

The Agency Protocol: Every placement must be scanned for all external links (OBL - Outbound Links).

• QA Threshold: If the page links to "Casino," "Porn," "Pills," or "Essay" niches, the link is rejected immediately.

• QA Threshold: If the OBL count is too high (e.g., a 500-word article with 50 external links), the page is a link farm. The value of your link is diluted to near zero.

2. Internal vs. External Ratio

A healthy page links internally to other resources on the same domain.

• The Red Flag: "Orphan Articles." These are pages created solely to sell links. They have no internal links pointing to them from the homepage or category pages.

• Why it matters: If the website owner doesn't link to the article, they are telling Google "this content is not important to me." If they don't value it, Google won't value your link inside it.

• QA Check: Using a crawler (like Screaming Frog or custom AI scripts) to ensure the URL has at least 1-2 internal incoming links.

Part 4: Technical Placement QA

Beyond the visible and semantic elements, there are technical attributes in the HTML code that can render a link useless.

1. The rel Attribute

• Dofollow: The standard link. Passes PageRank. This is usually what you pay for.

• Nofollow: Tells Google not to pass authority. Useful for traffic, useless for ranking power.

• Sponsored: explicitly tells Google "I was paid for this." While safe, it passes little to no authority.

• UGC (User Generated Content): Used for forum comments.

The Horror Story: A client pays $500 for a premium guest post. The article looks great. But in the code, the site owner applied a global rule making all external links rel="nofollow". Without Technical QA, the agency might miss this.

2. Indexability

A link on a page that isn't indexed doesn't exist.

• The noindex Tag: Some shady publishers accept the guest post but tag the page with <meta name="robots" content="noindex">. This keeps their site "clean" in Google's eyes while scamming the buyer.

• Robots.txt: Blocking crawlers from the specific directory where guest posts are hosted.

3. CLS (Cumulative Layout Shift)

This is a Core Web Vital. If the page loads and the text jumps around wildly (due to loading ads), users click the wrong things. Google penalizes pages with poor CLS. A link on a frustrated user's screen is not a high-value asset.

Part 5: The AI-Driven QA Workflow

How does a modern AI link building agency execute this at scale? We don't just rely on manual checks. We build automated pipelines.

Here is what a sophisticated Placement QA workflow looks like:

Step 1: The Render (Vision AI) The system takes the URL of the new placement. It uses a headless browser to "screenshot" the page.

• Analysis: Computer Vision calculates the vertical pixel depth of the link anchor.

• Pass/Fail: If pixel depth > 2000px, flag for review (Below Fold).

Step 2: The Semantic Audit (NLP) The text of the article is extracted and fed into an LLM (Large Language Model).

• Analysis: The LLM compares the vector embedding of the client's target keyword with the vector embedding of the article's topic.

• Pass/Fail: If similarity score < 0.6, flag for "Low Relevance."

Step 3: The Neighborhood Watch (Graph Analysis) The system extracts all href attributes (outbound links) from the page.

• Analysis: It checks these domains against a "Blacklist Database" (casinos, spam, known PBNs).

• Pass/Fail: If any blacklisted domain is found as a neighbor, automatic rejection.

Step 4: The Technical Health Check

• Analysis: Check HTTP status (200 OK), Robots tags, Canonical tags, and rel attributes.

• Pass/Fail: Must be Indexable + Dofollow.

Part 6: Why "Perfect" Metrics Can Fail QA

It is crucial to understand that a site can have perfect domain metrics and fail placement QA.

Example:

• Site: Forbes.com (Massive Authority).

• The Placement: You get a link on a "contributor" page.

• The QA Failure:

  1. Placement: The link is in the author bio, not the body text. (Low value).

  2. Attributes: The link is nofollow by default. (No authority).

  3. Orphaned: The page is not linked from any main category on Forbes. It exists only if you have the direct URL.

In this case, a link from a massive DR 90 site is practically worthless compared to a dofollow, contextual link on a DR 40 niche blog that is well-linked internally.

Part 7: Remediation – What to do when QA fails?

What happens when an agency identifies a bad placement? This is where the service quality is defined.

1. The "Edit" Request If the link is below the fold or the context is weak, the outreach manager contacts the editor.

• Script: "Thanks for the post! We noticed the link is quite low down. Could we move it to the second paragraph to fit the flow better?"

• Success Rate: Surprisingly high. Most editors don't care where the link is; they just pasted it in.

2. The "Niche Edit" Pivot If the content surrounding the link is irrelevant, we might ask to change the target URL to a different page on the client's site that fits better, or rewrite the surrounding paragraph.

3. The "Kill and Refund" If the site turns out to be a "bad neighborhood" (e.g., we find hidden casino links in the sidebar), we demand the link be removed (to avoid toxicity) and request a refund or a replacement on a different site.

Conclusion: QA is the Protector of ROI

In the world of SEO (keresőoptimalizálás), the most expensive link is the one that doesn't work.

Clients often obsess over the cost per link, but they should be obsessing over the value per placement. A $300 link that is above the fold, contextually perfect, and in a clean neighborhood is worth infinitely more than a $100 link that is buried in the footer next to a crypto scam.

Placement QA is the firewall that protects your budget. It ensures that you aren't just paying for a URL on a spreadsheet, but for a functional, authoritative asset that drives rankings and traffic.

The Future is Granular: As AI Search continues to evolve, it will become better at understanding the "sentiment" of a link. Was this link helpful? Was it placed with care? Agencies that ignore the granular details of placement do so at their own peril.

Your Placement QA Checklist

Before you sign off on a delivered link, run it through this filter:

• [ ] Visual Check: Is the link visible in the first 2-3 scrolls of the page?

• [ ] Flow Check: Does the sentence make sense grammatically and logically?

• [ ] Neighbor Check: Did you click the other links in the article to see where they go?

• [ ] Code Check: Is the link dofollow and is the page indexable?

• [ ] Image Check: Does the article have images/formatting, or is it a wall of text? (User Experience signal).
