Here's what we can do for you:

Hi, and welcome to Which Fly?

I'm glad you found us - so what do we do?

In a nutshell: We provide pre-qualified traffic direct to you.

Here's how do we do it - We provide clickable hatch information to fly anglers for individual counties. This information is generated from our proprietry technology which runs behind the scenes of this website which locates the user, then using a detailed database of hatches (built up over years of research and local expertise), presents the angler with insect hatches they can expect to see at that current date/time (they can even plan in advance). Not only that, we also give each angler the option to look at any county and generate the fly hatches for that location in any month of the year! All of the hatch information which is displayed can then be emailed to them automatically in a handy pdf. Pretty impressive eh?

What else do we do - Glad you asked, well we know that the key to getting customers in the first place is traffic generation, but they real value is in keeping hold of that customer. To do this in this tech savvy day, at a minimum, you need to have two things:

  1. Fantastic customer service - we cannot really help you with this, it's more of an ethos - but we can give you some pointers
  2. An up-to-date & pre-qualified email list - We CAN help you with this

Here's how we do it: Whenever an angler uses the Which Fly? site, they have the option of having the results emailed to them in both html and pdf formats. If they choose to have an email sent, they are automatically added to our database (part of the T's & C's on accepting emails). At the end of each month we send you a list of anglers who have agreed to subscribe to your list.

Want some proof it actually works?: This site has been developed in the UK to help our own online fly shop ( We have been successfully using ( for the last 18 months for our own purposes and this has seen our turnover double within that time.

For River Guides:

As a guide, you have great knowledge on the rivers in your local county. We know that when selecting a guide 'word of mouth' is an important factor, but if the travelling angler is new to the area, where do they look? With our platform showing hatch information per county, the anglers first port af call will be with us. What better place to advertise your guiding services directly on the county specific page? We will list your contact details (all clickable) and any relevant information and images you wish (so long as it's legal!). Here's the benefits to joining us:

  • We generate tailored/pre-qualified traffic to your website, every visitor is pre-qualified and ready to buy
  • We help your customer base, guiding service, website and profits grow
  • We build trust between your services and novice/travelling fly anglers, helping you retain customers
  • We promote the Which Fly website nationally with a comprehensive marketing plan
  • We supply you marketing materials for your own marketing initiatives
  • We provide all of this for a low monthly fee
  • So, how much for all of that? Well how does £30/month (per county) sound? We even give discounts if you want to sign up for a full calendar year - 12 months for the price of 10.
