How SEO agencies really get backlinks

The six ways agencies actually earn links

Every legitimate link comes from the same place: somebody decided your page was worth pointing at. An agency's job is to make that decision easy and then go and ask. There are six repeatable ways to do it, and most retainers run three or four of them at once.

None of them are secret. What separates a good link team from a bad one is volume of attempts, quality of the thing being pitched, and the discipline to keep going after the twelfth person ignores you.

• Digital PR and data studies. You produce something a journalist can write a headline from — original survey data, a price index, an analysis of public records — and pitch it to reporters covering that beat. Slow, expensive, and the only method that reliably wins links from sites you couldn't buy your way into.
• Broken-link outreach. Crawl the sites in your sector, find pages linking to dead URLs, offer your live page as the replacement. It works because you're doing the site owner a favour rather than asking for one.
• Resource-page outreach. Hundreds of industry associations, university departments and community sites keep "useful links" pages. If your page genuinely belongs on one, a short honest email gets it there more often than you'd think.
• Editorial guest contributions. A real byline on a real publication with a real editor. Fine when the publication would have commissioned the piece anyway. Spam when the only qualification is your card details.
• Expert commentary. Journalist request platforms and direct relationships with reporters. Your founder answers a question well and fast, and gets quoted with a link. Cheapest good link available if the founder actually replies.
• Linkable assets. A free calculator, a template, a dataset, a genuinely useful tool. Costs a lot once and then accumulates links for years without further outreach — the closest thing to compounding in link building.

What a link actually costs — the numbers agencies avoid publishing

Here's the part most agency blog posts skip, because publishing it makes the retainer look small. A link's cost is almost entirely people-time: prospecting, writing, pitching, following up, and being ignored. Divide the hours by the links won and you get an uncomfortable number.

These are the all-in ranges we see quoted and pay ourselves in the Indian market, in 2026. They move with sector, seniority of the person doing outreach, and how competitive the niche is. Treat them as ranges with reasoning, not a price list — anyone quoting you one exact figure for "a link" is selling you a placement, not outreach.

Guest posting: where the line sits

Guest posting is the most argued-about tactic in SEO, mostly because two completely different activities share the name.

One is writing for a publication your buyers read, with an editor, a standards process, and a reason to publish you beyond payment. That's PR with a link attached, and it has been legitimate since long before Google existed.

The other is paying a website ₹5,000 to host 800 words of keyword-stuffed filler that no human will ever read, on a site that publishes forty of them a week. Google's spam policies name that pattern directly — large-scale article campaigns built to pass link signals. The site selling them usually gets dealt with first, and your link stops counting the day it does.

The honest test is boring: would you still want this placement if links didn't exist? If yes, publish. If no, you're buying a link and should price the risk accordingly. We break the full comparison down in guest posting vs digital PR.

The three tactics that get sites penalised

Google's spam policies for web search are public and specific about links. These three show up constantly in Indian SEO proposals, usually under nicer names.

1. Paid links passing PageRank. Buying or selling links for ranking purposes violates Google's link spam policy, full stop. Paid placements are allowed if they're marked rel="sponsored" or nofollow — which of course removes the reason most people buy them. "Sponsored post", "paid collaboration" and "contributor fee" are all the same transaction.
2. Private blog networks. A stable of expired domains an agency owns, all linking to their clients. When an agency says "our own network" or "we have relationships with 500 sites", ask who owns the sites. PBNs fail in clusters — when one is found, every client linked from it takes the hit at once, and you never find out until your rankings go.
3. Mass exchanges and blasts. Reciprocal link schemes, link-exchange WhatsApp groups, automated directory submissions, comment blasts. Google's link spam updates use its SpamBrain system to neutralise these links rather than always penalising the site — which sounds gentle until you realise you paid for a year of links that now count for zero.

How many links a month is normal

Work backwards from the money. On a ₹75,000/month retainer, roughly 20–30% of hours go to links. That's around ₹15,000–₹22,000 of link budget a month. At ₹8,000–₹25,000 per earned link, you get one to three good links a month from outreach alone — more if a digital PR campaign lands, none in the months it doesn't.

Add citations, brand mentions that turn into links, and organic pickup from content you'd have published anyway, and three to ten new referring domains a month is a healthy pace for a mid-size Indian site. Slower is normal in months where a PR push is being built. Much faster is a purchase.

Volume matters far less than most founders expect. Ten links from sites your customers actually read will out-perform four hundred from sites nobody visits, and the four hundred carry risk the ten don't.

• Referring domains, not backlinks. One site linking to you 90 times is one endorsement. Agencies that report "total backlinks" are inflating the number on purpose.
• Relevance beats authority scores. A DR 30 site in your sector usually beats a DR 70 general news site for actual rankings, despite looking worse in the report.
• Steady beats spiky. A profile that grows smoothly looks like a business. One that jumps 400 in March and flatlines after looks like an invoice.

Auditing your agency's link work in ten minutes

You don't need a tool subscription or a technical background to check whether the link line item on your invoice is real. Ask for the list of links won in the last quarter and run this.

1. Open five of them. Does a real person appear to run the site? Is there recent, varied, human content? Would you email the site owner about a business matter?
2. Check the page your link is on. If it's a 700-word article surrounded by unrelated sponsored posts, you bought a placement.
3. Look at the anchor text spread. If most links use your exact target keyword as anchor text, that's a footprint. Real editorial links mostly use your brand name or the article title.
4. Check whether the links are still live. Bought links get removed when the seller cleans up or stops paying for hosting. Earned ones stay.
5. Ask where the next ten are coming from. A team doing real outreach can name the campaign, the target list and the pitch. A team buying links will talk about "our network".
