Tap in to the viral community
Reddit, the home of viral content, can be a valuable source of free traffic.
Find the best possible Reddit thread related to your niche and post quality links on it to your own site during peak hours.
Try a bit of Wiki-marketing
Look for broken “citation” links on Wikipedia. When you find one in your niche, write a blog article for your website that addresses the original citation in the Wiki article. Post your article and swap for the dead link.
Keywords are key words
Pretend you’re a customer for your own service. Which keywords will you search for?
Make sure you ask your customers how they found you and focus on using those keywords. Also, find out what keywords your competitors are using. Some good tools for this are SpyFu,Alexa, and OpenSiteExplorer.
Make your visitors advertise your site to their friends
Don’t just run a competition; run a competition that is won on the number of public votes an entrant gets.
Not only will you have drawn in people to try to win the competition, you’ll have actually made those people actively advertise for you.
Use the power of ‘cute’
Get an office pet and post pictures of it every day.
Get a good url (if it’s not too late)
Use keywords in the name of your business or in the URL of your site.
If selling garden toys in London, your domain could be: http://Londongardentoys.com.
Start a blog for your business…
…and put some effort into your content.
Google tracks how long users spent on your page to determine how useful it was to them, so the better your content is, the higher you rank.
Many businesses make the mistake of using their blog as a place to dump press releases. Your customers don’t care. Aim for 2,000 words of quality, informative content.
Get your logo and web address printed on balloons.
Rent a helium tank. Go to a crowded place (shopping centre, festival, beach, etc) and give them to children for free. Those balloons will be mobile billboards for your company and be at eye-level for every adult there.
Put a piece of paper with a promo code inside the balloon (and print text on the balloon telling them it’s there) so interested parents will pop the balloon later to get hold of it, creating a memorable interaction with your brand.
Generate backlinks, where other sites link to yours, by getting press, guest blogging, and conducting webinars.
Ask vendors, partners, press, clients, your alma mater and any other credible source you interact with to embed hyperlinked keywords back to your site for the terms you are targeting. If the referring source has a high page rank, you should see a pop in your rankings in less than two months.
Make yourself useful
Find people who are interested in your niche/business, either because they are looking for help or having issues on social media, blogs and forums.
If you own a business selling dog food, this means searching for people on forums wondering what dog food to feed their pet, for example. Provide the information they need and include a link back to your site.
