If you're a retailer, online sales may be more efficient (and allow you to cast a wider net), but in-store sales likely drive a significant amount of revenue, especially up-sell and incremental revenue. So how can you use your online presence to increase in-store sales?

The following is a guest post from Ryan Robinson, an entrepreneur and content marketing consultant to top startups and business executives.

Here's Ryan:

In the U.S., more than 81% of shoppers report conducting online research before making big purchase decisions. On top of that, nearly 50% of people who do local searches visit a store within one day.

If you own a brick-and-mortar business, that makes staying on top of the latest digital marketing tactics crucial to attracting customers. From social media to blogging and search engine optimization, having a strong online presence for your business can do much more than just traditional word-of-mouth and offline marketing alone.

Aside from being just another destination for selling your products outside of your storefront, your online presence is also a great place to provide free value to potential customers in a way that your competitors aren't. You can fortify relationships with existing customers and encourage repeat purchase behavior that'll help create advocates for your brand.

You may have a company blog that shares a behind-the-scenes perspective on the new line of t-shirts you're launching. Or perhaps you have an Instagram account that takes customers on a journey to the far-off coffee plantations where you import your beans from.

Regardless of what you sell, there are two basic principles you need to follow in order to boost in-store sales with online marketing tactics:

Drive traffic to your website and convert visitors into email subscribers.

Entice your email subscribers to visit your brick-and-mortar location.

First we're going to cover how to drive traffic to your company website, then focus on eight marketing tactics for getting those valuable subscribers into your store and buying your products.

How to Drive Traffic to Your Website

Before you can hope to increase online sales or convert your website visitors into foot traffic for your storefront, you need to have an active, healthy website with high quality content that motivates people to do business with you.

For most small businesses, that means keeping your existing community up-to-date and educating new potential customers with a company blog that publishes useful content regularly--at least twice a month. If you need some inspiration on what to write about from your company blog, here's a creative list of 40+ different ideas for blog posts from HubSpot.

Before hitting publish on your content, do some keyword research to make sure that your content is optimized for eventually rising to the top of Google's search results on a specific phrase related to your business.

For example, if you own a coffee shop in Brooklyn, you'll want to do everything you can to rank well in local search results for "coffee shop Brooklyn," to maximize the amount of foot traffic coming from people who are searching online for coffee shops to try out.

One way to rank at the top of these search results could be to make your website the authority on coffee in Brooklyn by publishing a huge roundup post on your company blog, highlighting an unbiased review of all the major coffee shops located in Brooklyn. Be sure to lead the list with your own location and emphasize authentic customer reviews sourced from Yelp or otherwise, rather than being overly self-promotional.

When thinking about the types of search terms your customers are using online, start by asking yourself the question, "Who are my customers?" If you're not completely sure of the trends and commonalities between your existing customers, do a bit of demographic research by polling your most recent or engaged ten to twenty customers rather than making guesses.

If you run a graphic design and print shop that specializes in high quality business cards, you'll probably want to target business executives in their 40's or startup founders that constantly network and attend trade shows. If you run a travel agency that caters to backpackers, you'll probably want to target young professionals who can afford to travel and want the authentic local experience wherever they visit.

Depending on the kind of people you're interacting with, you want to find them on the right social media channels. If you do B2B marketing consulting, you may want to run a sponsored post on LinkedIn or an ad campaign through Twitter.

If you're targeting direct consumers rather than commercial clients, focus on growing your audience on Facebook, Instagram or Pinterest to get the best reach for your demographic. Check out this definitive guide from Hootsuite to figure out which social network is right for your business.

How to Generate Email Subscribers

Once you've optimized the content you're publishing on your website, the next step is converting your readers into email subscribers for your business.

Be sure to include a prominent call-to-action for readers to subscribe across your website, in the sidebar of your blog and strategically placed within your blog posts, to maximize your opportunity for capturing customer emails.

If you own a product-driven business, incentivize your readers with an immediate online or in-store discount in exchange for signing up for your email list and employ inexpensive or free tools like Sumo's List Builder and OptinMonster to create visually appealing email opt-in forms, display exit-intent popups, and more to increase your conversion rates.

For service-based business owners, consider offering a free download, do-it-yourself template, authoritative eBook or complementary phone consultation in exchange for readers to sign up for your email list.

If you can provide massive upfront value to your readers in a way that other local businesses aren't willing to do for free, you'll put yourself in a position to build meaningful relationships with your readers--and convert them into customers.

6 Marketing Tactics for Converting Email Subscribers into In-Store Customers

Once you have a growing email list of people who love your brand or at least your content, it's time to begin experimenting with bringing them into your store and incentivizing them to buy from you. Here are six creative tactics to get you started.

1. Theme Days and Events

Get people to show up to your store by hosting events that include the things they love. Even if you make an exciting product that practically sells itself, like gourmet cupcakes for example, you still need to build context around what your business does, who you are and what you want to represent within your community.

This is especially important for businesses that don't have excitement or shock value built-in, like if you sell office furniture.

Plan an event that'll bring your email subscribers through the front door. It doesn't always have to be related to what you sell, either. Going back to your demographic research, if you've uncovered that the majority of your customers are pet owners, consider hosting a doggie day at your consignment boutique, a smart and growing trend in retail.

Alternatively, you could plan an event that aligns more directly with what your business does for your customers. If you own a farm-to-table restaurant, hosting a monthly cooking class that teaches customers about where the produce and meats they consume actually comes from could be an additional revenue stream that serves to get your most loyal customers even more engaged in your brand.

2. Flash Sales

It's not enough to send your subscribers a monthly coupon for 20% off their next purchase and expect them to show up at your store in droves. You have to create a sense of urgency. Send your subscribers a coupon for their next in-store purchase and tell them they have only 72 hours to redeem it.

Research shows time and time again that urgency works wonders in marketing. Tapping into the human fear-of-missing-out (FOMO) response is a surefire way to push people over the tipping point when they're already interested in what you have to offer.

3. Partner with Local Charities

Helping out whether through donation of funds or committing time to a good cause in your local community is a win-win, especially if it's well-aligned with your business. Why not get involved in issues that matter to you and your customers?

If you're not sure which causes your customers care about most, send out a quick survey using Google Docs and ask them to vote on a few options you're considering.

Once you've gotten that feedback, send a follow-up email with plans for your first fundraising event or details about what percentage of sales from each purchase will go to the philanthropy of choice next month. Whether it benefits the local no-kill animal shelter or raises money to support Habitat for Humanity, this gives your customers a sense of ownership and involvement in your business, which can foster a lasting relationship based on more than just transactions.

Not only do you extend your brand's local image and get the local community talking about you in a positive light, you'll do some genuine good in the world at the same time.

4. Click and Collect

In some cases it might actually be easier for customers to order online and come by your store to pick up their purchase from you. For example, if you run a furniture shop that sells handmade wooden tables, local customers can save on shipping by picking up the product from you instead--which also reduces the amount of work your team has to do.

Retailers like Kohl's have successfully deployed this click and collect strategy to revive many of their struggling brick-and-mortar locations--there's no reason your store can't do the same. You can also glean a lot of valuable data on your customers by employing this practice.

Kohl's found that 75% of their click and collect shoppers were enrolled in their loyalty program, which suggests you too might be able to create more recurring business with the people who are really into your products.

5. Retargeting Campaigns

Ad retargeting is a smart and proven method for bringing in more sales from people who've recently visited your website by surfacing ads to them across the web. By using a retargeting vendor like AdRoll or ReTargeter, you can install a tracking pixel on your website that'll set a cookie in your visitor's browser, which allows you to display advertisements to those visitors on other participating websites they visit for days, weeks even months after they're on your site.

With your email subscribers, you're speaking to people who already trust you enough to give you their email address. They're more likely to buy from you than someone else if you stay top of mind when they're ready to make a purchase.

6. Joint Partnerships

Go back to the demographic research on your customers and consider some of the other products, services and experiences they probably love. If you're not sure, ask them! Are your customers into gourmet chocolate? Chances are, they probably love good coffee, too.

Reach out to other businesses in your area that sell something your customers probably like and forge a joint partnership to co-promote your brands together. Host a chocolate and coffee tasting event after hours at your cafe and promote it to both of your email lists, distribute flyers and run a Facebook Ad campaign targeting local customers to get them out for your event.
