How to compare content marketing proposals

1. Fix the unit before you compare the price. A piece can mean a short summary written from search results or a researched article involving an interview with somebody who does the work. Agree word count, research depth, interviews included, revisions and who signs off, then compare. Without a unit definition, quotes are not comparable at all.
2. Ask who writes and whether you can see their other work. Named writers with subject knowledge cost more and produce material a buyer in your category will not immediately discount. Ask for two samples by the person who would actually write for you, not agency showcase pieces produced by a team that is no longer there.
3. Tie every piece to a query and a decision. Each piece should name the search it is aimed at and the buying decision it supports, agreed before production. A calendar built on themes rather than queries produces output that reads well and ranks for nothing, which is the most common way a content retainer quietly fails.
4. Agree the distribution, not just the production. Publishing is not distribution. Establish what happens after a piece goes live: internal linking, updates on a schedule, promotion, repurposing. Content with no maintenance plan decays, and a retainer that only funds new pieces is paying to replace value it is allowing to erode.

What drives the price of a piece

Four things, and the price gap between the ends of the market is almost entirely explained by them. Research depth: whether the writer read the sources and spoke to a practitioner, or paraphrased the current top results. Subject expertise: a general writer covering a technical field needs a review step, and the review is where the cost either appears or is quietly skipped. Editorial process: outline approval, a real edit, fact checking and a revision round. Rights and process overheads: briefing, project management and reporting, which are real labour even though no words are produced.

Google's guidance on creating helpful, reliable, people first content is the most useful buyer side reference here, because it describes what the search engine is trying to reward: content produced for people, showing first hand experience or depth of knowledge, that leaves a reader feeling their question was answered. Read a candidate's samples against that description rather than against a word count. A brief that requires an interview costs more per piece and is generally the cheaper way to get material that survives contact with an informed reader.

What agencies publish, and how to use it

Our index records what each agency states on its own site, with the date we checked it. Content agencies publish price more often than most other categories, because per piece and per package pricing is how the volume end of the market competes, and because buyers of content genuinely do shop on a number. That makes the published range useful, provided you normalise for the unit, since a low per piece rate almost always assumes a shallow research standard rather than a more efficient writer.

The most practical use of the published range is as a reference before you speak to the providers who publish nothing. Establish what the market charges for the unit you actually want, including research and editing, then compare a bespoke proposal to it directly. When a quote sits far below that range, the question is not whether the agency is cheap, it is which of research, expertise or editing has been removed to get there, and whether you can live without it.

Questions people actually ask

How many pieces a month do I actually need?

Fewer than most proposals suggest, aimed better. A small number of genuinely useful pieces targeting queries you can compete for will beat a high volume calendar covering the same ground shallowly. Volume matters when you are building coverage of a large topic area with real depth behind each piece, not as a substitute for depth.

Should the agency also handle publishing and technical work?

It is convenient and it is not required. What matters is that somebody owns internal linking, page structure and the update schedule, because unmaintained content decays. If the agency does not do it, name who does on your side before the first piece goes live rather than after fifty of them are live and unlinked.

How is content performance measured fairly?

By query level movement and by assisted enquiries over a horizon of quarters rather than weeks, since a new piece takes time to be crawled, ranked and trusted. Ask for reporting that tracks the specific searches each piece was aimed at, which also keeps production honest about the brief.

Who owns the content?

You should, outright, with no licence that expires when the retainer does. Ask specifically about content published on the agency's own platforms or microsites, which is the material most likely to disappear at the end of a relationship. Agencies rarely object, but the question has to be asked before signature.
