Hi Andy
First things first, I thought you had an MLS listing, (which would show up in your profile and give a link to your site in your signature. I've had a look but can't find one, or a deleted one (in case you haven't clicked our auto are you still their email).
As a quick fix, I've added your weblink to your signature. Feel free to list again and I'll upgrade you (as a long time forum veteran!), just let me know when you have (PM me).
But we are in serious times, so think overhead and cash. Don't waste money now on anything that isn't working. If PPC isn't working right now, then stop it, save money, regroup and replan.
If the website isn't really working right now and you're getting little traffic, then concentrate on new avenues. Everyone is at home, everyone is living on social media. Take advantage, you have a captive audience. People still have birthdays, anniversaries, celebrate events. If anything you are perfectly poised to capitalise on this.
You are currently furloughed, so have buckets of time. Make the most of it.
Look at your social media presence, look at your branding, look at the type of posts you are putting out.
If it was me, I'd give my FB page a makeover. Don't just share images of tankards and a link to your website, that's lazy selling that generates nothing. Tell me why I need to buy a tankard. Tell me this is the perfect gift for someone I love but can't see. Tell me I can have a personal message engraved. Tell me why your service is above and beyond and better than Amazon.
Look at your posting frequency, live on Facebook, make it your shop front. You did a good post for Mothers day, then did 2 lazy posts on 2 and 3 March, then a joke post on 22 March.
I'd be making my page look the best I possibly could, I would be working out a posting schedule, I'd be looking for FB groups to join, looking for ways to get my message out there. I'd be putting posts out which are engaging, positive.
Maybe send your local hospital a big plaque with a thanks from all of us, or even Tescos. Then shout as loud as you can without being too obvious! There are thousands of marketing ideas if you sit back and think about it. This would be a good place for a bit of PPC, a £10 boost here or there will give you a reach of thousands. If your page looks the part and your message is good, then that's a lot of possible eyeballs who need to buy presents.
I've seen my social media traffic explode. I've completely readapted and (for my Trusted Trader business) have become an information service, pushing out official information, breaking down FAQs into easily digestible information, offering guidance on interpreting official policy. My twitter following has doubled in the last 7 days.
I've yet to start with MLS, step 1 get active again in the forum. So we are all learning, all adapting.
Be proactive, you are in an industry that can keep trading products online, and have a captive audience who are desperate for ideas in how to make an event, milestone or important day special.
Now is your time. To be honest, if you don't make money now, you never will. Sod the website, that's vanity and for simply sending people to buy stuff. Make sure the check out process is as slick as you can make it, otherwise don't waste time on it. Go to where the traffic is, social media.
Be proactive, be positive, react quickly and start owning the pewter space. Your mission is to make me think, blimey I need to buy some Pewter and Andy is that man
