How long does an SEO company need for competitor analysis?

It depends on how many competitors are reviewed, how large their sites are, how many locations and kinds of search the analysis has to cover, and how far it goes beyond collecting data into explaining what to do. No figure fits every business, and a company that quotes one before it knows your market is guessing. Ask instead for a written estimate that names the competitors, the areas to be covered, and the form of the finished work, so you can tell whether a short estimate means a small market or a shallow review.

What the time is spent on

A competitor analysis is a sequence of reviews, each built on the one before. The company first works out who your search competitors are, which can differ from the businesses you compete with for customers. It then looks at which searches those competitors appear for and you do not, how their pages are structured and how thorough they are, which sites link to them, and how their sites are built. The last step takes the most judgment: explaining why particular pages outrank yours and what you should change as a result.

Why there is more than one set of competitors

The pages you compete with are not fixed. Google’s explanation of how Search works says that relevance “is determined by hundreds of factors, which could include information such as the user’s location, language, and device (desktop or phone).” Its example is that a search for bicycle repair shops “would show different results to a user in Paris than it would to a user in Hong Kong.” The same page notes that the kinds of results shown change with the query, so some searches bring up local listings and others do not.

For the analysis, this means the competitor set has to be checked for each area you serve and for each type of search that matters to you. A business serving one town with a few services has one manageable picture. A business serving several regions, or selling both locally and nationally, has several, and each takes time.

What makes it take longer

The number and size of competitors set the volume of work: a handful of small sites can be reviewed faster than large sites with many service lines or a large body of articles. A crowded market adds more pages and more links to study. Depth adds time too, because a list of competitor keywords is quick to produce, while an explanation of why those competitors rank, and what that means for your site, needs someone to read and interpret the data rather than export it.

The first analysis and the follow-ups

The first analysis builds the picture from nothing and is the larger piece of work. Later reviews update that picture: new competitors, pages that have moved up or down, new content and links. They should take less time because the groundwork exists, so ask whether the estimate covers only the first analysis or follow-up reviews as well, and how often the company plans to repeat them.

Checking an estimate before you accept it

Ask the company to name the competitors it will review and how it chose them, which locations and searches it will check them for, and whether the finished work is a set of data or a report with recommendations. Ask what the estimate assumes, and how it changes if your market turns out larger or more crowded than expected. An estimate that comes with those answers is one you can hold the company to.
