Building a local, travel-oriented website, part II

I previously posted on here about a month ago, explaining my journey into this project so far. I am posting here primarily for myself, in an attempt to try to organize my thoughts about the project I am passionate about, but I am also very hopeful that someone will be able to provide an angle or feedback I haven't thought about.Recap: For the last seven months or so, I have been creating a local tourist-oriented website about my hometown, a mid-size European tourist hub that draws around a million visitors per year (pre-Covid), hoping to fill a niche that does not really exist in the scope I envisaged it.As a long-term Airbnb host, I have been faced with all kind of questions tourists ask me, but instead of being able to provide them with a simple link where the things they ask are explained, I always had to get to writing. Over time, same questions kept popping, which made me realize, that a local travel website that would fulfill this need would be very much welcome.Fastforward to today, I have created the 1.0 version of my website that has the answers to the most frequently answered questions as well as a directory listing of +150 restaurants, bars, shops, nightclubs, beaches, museums and landmarks. Since April, the traffic to the website has been doubling or tripling consistently, but the growth seems to have significantly slowed down this week, just after having reached the 1000 monthly users and 2000 monthly views milestones.The Problem: I got most hits for several "seasonal" things, like reporting rumors about a local music festival (2 out of my top 5 visited pages), and by simply having a profile for the restaurant freshly opened by a popular local celebrity chef which was written about in local newspapers and apparently resulted in a large number of searches.Now the rest of my pages all seem equally popular, there seems to be a high interest in restaurants, which i expected, and my website appears quite high in searches for individual restaurants, because, naturally, they are mostly found on tripadvisor, facebook and/or instagram.​However, I am a little lost on how to get more traffic to my website.I was thinking of doing no advertising for this summer (my hometown is a seasonal tourist spot) and just let the google algorithm take me for a ride wherever it wants. The results have been okay-ish, but nothing spectacular, so I am trying to get an idea how much money to invest in order to gain a share of the traffic.According to Alexa and similar sites, I estimate that my #1 competitor, which is the official website of the local tourist board -- which has no useful information online whatsoever -- gets around 50.000 monthly views. So I guess getting that is the ultimate goal years down the road.​Goal #1: I would like getting something like 10k monthly views by the next summer, because with that I can already make approaches to local business and start monetizing the website. Hence my questions: how to get there?I want to target two audiences: the airbnb renters like myself, who would find value in the website and share it to their guests as it would make explaining things easier for them (i.e. sharing my article on beaches, or on best pizzerias in town, etc -- i noticed these are some high performing pages). I was thinking of paying for an add in an yearly magazine for short-term-renters that comes up with the popular regional newspaper here, but it costs something like 400 € (470$) for the smallest ad (1/8 of the page) and might not even reach my target audience because I have no clue whether they are reading it or not (i, personally, am not...). it might be better to invest a portion of that money for fliers that I can go putting in mailboxes around the old town of my hometown, where the majority of renters rent.but any tips of alternatives on how to reach this particular audience would be super helpful.​audience number two is of course the travelers to my town. though it would be spectacular if i can get airbnb renters to advertise me indirectly, I think the most basic strategy should be paying for google ads. however, what I don't really get, is how much should i pay for this. I have never done it before, and I am very careful not to be burning money on things I dont fully grasp, but I also understand I won't really get it unless I try.I do have enough money to really not having to worry about having any kind of fixed budget, but I would of course like to know a general return on the investment before I start splurging.what I would like to hear is someone with experience tell me something concrete, albeit not necessarily 100% correct, something like investing X € will be better than Y € because it is more sustainable long-term etc.​Thank you for reading this. see hubwealthy.com/wealthy
