Short answer
Usually, if people search for what you sell in the places you sell it. SEO is slow, nobody can guarantee rankings, and it suits businesses with steady search demand better than one-off sales. The basics are mostly one-off fixes, so start there before paying for anything ongoing.When it is worth it
When customers look for your kind of business on Google: a dentist, an accountant, a plumber, a florist. Those searches happen every day, and the people making them are ready to choose. A good position puts you in front of them without paying for each click.
You can check demand for free. Type your service and town into Google and see what it suggests; those suggestions are searches people actually make. If you already have a site, Google Search Console shows the searches it appears for.
When it isn't, yet
- Nobody searches for what you offer, because the category is new.
- You need customers next week. SEO takes months; ads are faster.
- Your website itself is the problem, such as a slow or broken site. Fix that first.
What it costs
In Ahrefs' survey of 439 SEO providers, “$501–$1,000 per month is the most popular monthly retainer rate for SEOs”, and the average across respondents was $2,917 a month (Ahrefs, updated August 2024).
Start with the basics
A lot of what holds small sites back is fixable once, not monthly.
A warning
Anyone who guarantees a first-place ranking is promising something they don't control. What a good provider can promise is honest measurement and work you can see.
