SEO Company transparency

Good deal for them and not very good for you. Manual SEO takes 3-6mths (normally), so they string you along as you seem pretty level headed and trust other people are the same. It doesn't work that way anymore, most SEO are having serious issues with keeping up and actually don't know themselves what to do. Never had this problem as outsource it all via via (an incubator to their consultants), rank sites in days but do have digital media management services (listed on Bloomberg too).

Will they tell you exactly what they are doing, not likely. Deal with behavioral science in eCommerce which what drives your revenue and ranking, what is you CLV, your CPO, product volume, who are the competitors, how does you platform compare, what technical architecture are you running, what is your marketing budget breakdown (organic/seo is 23% of 4-8% of revenue). If you don't have the same services as your competitors and no answers to those questions, it's never going to go well. We were always told one thing by these consultants, if you are not sure walk away, the good companies will wait for you to come back, the bad ones will try and pull you back in or bribe you to stay.

You have mentioned
"They have corrected several errors on my site and advised me of changes that needed to be made and they have set up Google Analytics to a very high level. I get reports for various aspects of the project such as keyword research and reports about how the keywords are performing as well as duplicate content reports etc"

Still you have issues with company's transparency ? Are you locked in for a term say 6 months or so ? Depending on the complexity of the website these rates are fine. For almost everything there is a free version. But when you really start using it ; you find the learning curve and practical difficulties.

These days, lots of SEO company not showing the transparency in their business, they just getting the money till 6 months and after that client want to pay them because they didn't provide the satisfactory result.

I recommend you, must choose that company who offer search engine ranking on per keyword basis,

No, you are not. But they're sending you reports. The reports tell you what they're spending the time on.

It sounds like you expected better results and want to know that whatever they're doing will, indeed, get you enough extra visitors to your site so you can get more clients.

Which is normal and healthy.

SEO companies come in 2 flavors: the ones that charge by the hour the ones that charge by results.

The ones that charge by the hour get results (they fix errors on pages, for instance, or publish 1 slide-style video on youtube with the right keywords in the title and description, they increase your footprint, but not necessarily your traffic).

The ones that charge by results say they'll increase traffic by a significant number.

You got the first kind. Which means, you should have told them what to do, if you wanted to be higher up in Google by a lot.

You probably picked a package, but I'm sure they can be persuaded to do a la carte. A la carte, if you pick the right things, has better chances of getting your more clients than if you pick a package
