What are common social media content marketing mistakes?

Social media marketing is a great way to boost your business and profits. However, there are many common mistakes that people make when engaging in social media marketing.

If you’re making any of these mistakes, don’t worry. It’s never too late to fix your social marketing and make it better.

Not interacting with your followers

When your followers comment on something, share or ask a question, don’t wait too long to respond. If you have someone monitoring your social media, ask them to update you on ongoing conversations and potential areas of engagement.

Not filling out your profile completely

Incomplete profiles make your business look sloppy or fake. If you want to be taken seriously, fill out a complete profile with a good profile picture, your company logo/banner, and information so they can contact you offline.

Do not focus on the quality of the follower

Some people make the mistake of focusing on the number of followers instead of the quality. You want to worry about finding followers who are potential customers.

Not posting regular and relevant updates

If you’re not actively posting things that resonate with your audience, then you’re not going to get any traction. If you plan to be successful with social media marketing, it takes perseverance and patience, not one-hit wonders.

Not choosing your channels wisely

It is not necessary to be on all social networks. Be on the channels your audience loves and that will do just fine.

Do not automate some actions

There are many things, like scheduled updates, that you can automate on social media. Be sure to use programming when possible, as long as it doesn’t make you seem robotic.

Do not interact personally

Whenever you get the chance, it’s important to make spontaneous updates that are relevant to your business and your goals. This will make you look more real in the eyes of your followers.

Do not customize messages for the channel

Sending a mass message, using software, to all the social networks you have connected with is a big mistake. Most of the time, you will have leads that are in more than one account. If you do this, they will quickly get bored or worse, spammed.

Using social media to market your business is a proven technique for getting more customers, making more sales, and increasing your bottom line, but only if you avoid these mistakes. Take one at a time and make the necessary improvements to get you on the right track and making your social media marketing profitable for your business.

But Instagram has become a social media powerhouse. It has become a great place for businesses and brands to connect with their fans and increase sales. In a month, more than 120 million people on Instagram will visit a website, get directions, call, email, or direct message for information about a business based on what they saw on Instagram.

Instagram is incredibly easy for anyone to use. Even if you don’t have much experience when it comes to social networking websites, you’ll find that Instagram has a very user-friendly interface that you’ll learn to use effectively in no time. It’s a great way to give your business some personality and pique the interest of customers.

How to make a good YouTube video

First of all, I want to congratulate you on leveraging YouTube videos in your content marketing strategy. It is a wise choice. The demand for video content continues to grow and you don’t want to be left out of the game.

43% of people want to see more video content from marketers.” (HubSpot, 2016)

But how are your videos going?

If you regularly post videos but don’t see any increase in views and engagement, you may not be thinking enough about your video creation process.

Why is video quality crucial?

You’re probably tired of hearing that quality is important. But I can’t stress enough how important this is.

You have to increase the ranking of your YouTube videos so that people find your videos and have a chance to enjoy them.

While it’s true that the quality of a video doesn’t directly influence YouTube video ranking, it still carries a lot of weight.

If the video is bad, no amount of YouTube SEO can make it shine.

Let’s say your video ranks high in search results and people click on it. But the video quality is poor and users click again after a couple of seconds.

In addition to not having the opportunity to convert viewers into customers, this behavior seriously hurts your ranking.

How is that?

One of the main YouTube ranking factors is audience retention.

The longer users watch your videos, the more higher ranking. YouTube wants its users to stay on YouTube as long as possible, so if you keep your audience engaged and engaged, you’ll be rewarded for it.

As YouTube states in the Creator Academy: “Your goal is to keep audience retention as close to 100% as possible (because that means viewers watch all of your videos). And videos with audience retention and Consistently high watch times have the potential to appear more often in search and suggested locations on YouTube.”

I hope you are now convinced that you should put some effort into creating compelling content that will keep your audience interested. until the end of the video

How to create videos that keep the audience watching?

High quality audio and visuals – How you deliver your content in terms of audio and video quality plays a huge role in retention. If the sound or picture is bad, people won’t stick around long enough to find out what they can learn from you.

Let viewers know what they will learn at first: About 20% of viewers will fly away after the first 10 seconds of the video if they’re not sure the video is showing them what they’re looking for. Be sure to point out what they will learn at the beginning.

Introduction – Like I said earlier, it’s easy to lose viewers in the first 10 seconds. You want to make sure your intro is engaging and captivates viewers’ attention so they stay present throughout the content.

don’t ramble – Especially if you’re just starting out, you’ll be tempted to create those long introductions with unnecessary information that tend to put people to sleep. Keep your introduction on point and go to the main content.

Write your videos – Don’t get in front of the camera and start talking. Plan your videos in advance and save them. This will ensure that you stay on point and cover the most important aspects of the topic without losing your ideas along the way.

Predict audience questions – One way to pique viewers’ curiosity is to address questions they might have, which you’ll answer later in the video. Let’s say you do a tutorial on how to be more productive and you mention the Pomodoro technique at some point. Saying something like “You’re probably wondering what the Pomodoro Technique is. I’ll get to that in a minute” will keep viewers interested in continuing to watch the video.

final thought

Give enough thought to video creation as it will not be enough to just have content. You can do as much YouTube SEO as you can for your videos. If the content is bad, your videos will not be ranked.

When you have high-quality content and perform video SEO optimization, you will almost certainly rank YouTube videos on the first page.

Boosting Website Ranking: A Simple Technique That Works

We all want to have good rankings in Google, it’s no secret. The better we rank, the more traffic we receive and the chances of our business making a profit also increase. This article explains a technique that can help your site rank better in Google.

The technique:

Google is a search engine that wants to give its users the best possible experience, they hold their search engine to the highest standards. They want everyone to have instant gratification when using their search engine.

One way to earn the respect of the big “G” is to register your domain names for more than 1 year. Yes, this has come up in many SEO communities and many have agreed that having a domain name, registered for more than 1 year, gives instant credibility with Google.

If you register your web address for 5-10 years, it tells Google that you are in business for a long time and will stay more than 1 year and will not go away. This builds trust with the super search engine and will give you an SEO boost.

By doing this, you won’t instantly rank at the top of Google results. All of these little factors add up to good rankings in the end. The next time you want to register a domain name, why not do it for 5 years and show Google how serious you are about providing quality business on their search engine? They will give you an on-page SEO boost and you will be ahead of your competition.

As I mentioned in my other articles, you still need to do proper off-page optimization for your sites to rank well in the big “G”. Registering your web address for more than a year only makes the chance of ranking better that much stronger.

Micro Niche Finder – Secret Formula for Competitor Strength Calculation

Micro Niche Finder (MNF) is an excellent keyword analysis software. For each niche market, you get a list of similar and related keywords. For each keyword, you get local and global search counts, Google search trends, exact phrase counts, ad cost, online business intent, backlinks measure, and SOC: search strength. the competition. This parameter is crucial to correctly estimate the effort required to be successful with this keyword.

For a profitable micro-niche, you need phrases with high search volume (lots of people searching for this word) and weak competition (small number of pages related to it). Search volume needs no further explanation. It is the number of monthly searches. More searches mean more potential visitors, more visitors means more chances to sell items or services. However, the number of pages related to your target keyword can be used to estimate the competition, but the number itself says little about the content on the competitor’s pages. Fortunately, Micro Niche Finder provides an additional feature to estimate strength of competition (SOC).

This SOC parameter is a simple number. If it’s below 50, it’s green, which means weak competition and little effort is needed to rank high for this keyword. Higher SOC values ​​mean more effort is needed to rank higher. If you click on this SOC number, you get three additional parameters: inanchor count, intitile count, and inurl count. These three parameters are directly related to the Google search operators, in fact, they are exactly the operators used in the search query. In this way you get the number of pages where your target keyword is present in the anchor text of a link, in the title of the page or in the URL. The question is how is the Strength of Competition parameter calculated?

Here’s the secret formula: the SOC parameter is the intersection of the pages with the three search operators. Simple as that. In other words, the parameter strength number displayed in MNF is the number of pages that have the target keyword in the page title, URL, and anchor text at the same time. The MNF searches up to 1,000 results. This is the actual query example for the keyword “long domain name”:


This is a part of the Google search query URL, you need to enter it in the browser’s address bar after

As you can see in the query parameters, the starting number is 900 and the num parameter is set to 100 to get the actual number of intersecting pages up to 1000. The best way to test this formula is to enter the query in your browser and try it with your keywords.

6 ways to increase sales after the holidays

Your Business Guide to Beating Post-Vacation Fatigue

It’s no surprise that people shop more during the holiday season. A report from Adobe Analytics found that consumers spent $80.3 billion — and that was online alone — from November 1 to December 6, 2018.

If you were lucky, your business enjoyed great seasonal success.

But whether you’ve made a big profit or experienced a dip in holiday sales, there are ways to increase sales in January. I am sharing 6 of my favorites:

1. Launch another sale.

While customers may feel post-holiday fatigued after an overwhelming number of Black Friday, Cyber ​​Monday, Christmas, and Boxing Day deals, you can still reach your target audience with a tempting winter discount.

Here’s a good example: Home and clothing retailer Anthropologie is having a winter sale on all sale items. By taking another 40% off items that are already at a reduced price, they are enticing customers and removing old stock to make room for new spring inventory.

Remember that your fans are smart, so be authentic instead of just putting a sale sign on a poorly selling product or calling a small discount “winter clearance.”

2. Bind New Year’s resolutions.

No matter what product or service you’re selling, there’s probably a way to tie in the “New Year, New You” angle.

A 2018 survey by Tangerine found that nearly 70% of Canadians have made resolutions. More than half of those surveyed focused on improving their physical health and almost a third wanted to improve their financial management.

So start by thinking about how your product or service improves:

  • Financial, personal or professional success.
  • health or wellness
  • Confidence or self-esteem
  • productivity
  • Relations

Then, brainstorm ways you could incorporate New Year’s resolutions and goals into your sales program to avoid a post-holiday sales slump. For example, we created a publication for one of our clients, using personal success in 2020 to drive sales of their book Crash Course in Human Resources for Small Businesses.

3. Create a buying guide or blog.

While we tend to pay most of the attention to Christmas, don’t forget that people want gift ideas all year long.

According to the 2019 Holiday Shopping report, 47% of surveyed gift shoppers didn’t know what to buy. To turn browsers into customers any time of year, guide your visitors. For example, you can create a list of the top 10 popular gifts for teens or moms, or highlight the most popular gifts for Father’s Day.

People will be less overwhelmed and more likely to add an item to their cart with a little guidance, which can really help you boost post-holiday sales.

4. Update your newsletter subscription.

With so much going on in the life of a small business owner, it can be easy to overlook this important marketing tool. Are you offering an ebook that has been active for years with a newsletter signup or promoting an outdated promotion?

Take a look at your e-newsletter subscription page and think about the year ahead. Is there a way to make it more attractive to attract leads and sales?

Maybe you could create new content, like an ebook or video tutorial, or offer a free consultation.

5. Improve your social networks.

If you gave your social media accounts a festive touch, now is the time to take down the decorations, so to speak. Even if you didn’t add any Christmas flair, now is a great opportunity to reflect on the messages you’re posting.

While you shouldn’t update your logo or branding just because it’s a new year, at least do a sweep of your social media to see if you need to change/add:

  • Your business hours and location on Facebook and Google My Business.
  • Old tweets pinned to your Twitter account.
  • Images for Google My Business and Instagram.
  • Profile photos for all your social media accounts.

While you might argue that this isn’t a direct way to increase sales after the holidays, you’d be surprised! If you have old assets gathering dust or can’t be bothered to change a Christmas sign on a social media platform, people may wonder how efficient and trustworthy your small business is.

The Right Reasons to Rebrand Your Company Logo

Over time your business will grow and evolve. You can offer new services or products, enter different markets, or target another demographic. If this happens, you may need to consider changing your marketing graphics.

However, you need to be careful not to undo all the hard marketing and branding work you’ve put in and to fully understand how to rebrand for the most effective results. Read more on our website.

6. Get creative with celebrations throughout the year.

There’s a long list of January “holidays” you can check out online to help you get started. As you take note of relevant dates throughout the year, there are sure to be some fun ways to incorporate them into your marketing strategy.

You could offer a discount, a free gift or a promotion related to what you sell. Here’s a delicious example: Italian chain Carrabba’s Italian Grill celebrated National Pasta Day last year with a $10 pasta deal.

One of my favorite examples is what WWF did for World Penguin Day (April 25th coming up!). They shared an informative article “Top 10 Emperor Penguin Facts,” with a call to action to “adopt” one of these lovable waddling birds.

This campaign wowed us so much that we adopted some ourselves! Since the Emperor Penguin is our official mascot, why not?

No, we didn’t get our own penguin, but we did get a plushie, regular updates, stickers, and other cool stuff to support the initiative.

There is no reason why you should wait and accept a drop in sales after the holidays. While we tend to focus a lot of our marketing (and staffing) energy on the festive season, we need to remember that our customers are still out there! They want to hear from us in a meaningful and relevant way.

With a little planning and creativity, you can overcome post-holiday fatigue and set your small business up for a prosperous 2020.

The Booming Catering Industry: Facts and Statistics

Factual and statistical information

Worldwide catering market revenue is expected to reach US$265 billion within 4 years, with an estimated compound annual growth rate of 5 percent according to Research and Markets. Significantly, the market spans major sectors in various communities, including schools, senior facilities, sports centers, and even hospitals. These institutions outsource their food service needs so they can lower their expenses and focus their workforce on more important matters.

A recent study by Technomic shows that the US restaurant industry generated about $537 billion in total sales last 2017 with a continuous growth rate due to easy and fast online ordering system. There are more than 10,000 catering companies in the United States, employing about 110,000 people in total. Most of these companies are small and locally controlled and do not account for a large part of the market share. The demand for their services is higher in densely populated areas.

The largest catering market in Asia and the second largest in the world, China achieved an estimated revenue of US$616 billion as reported by the China Cuisine Association. At the moment, it has around 5 million companies active in the restaurant sector. This has been attributed to the implementation of an online-to-offline marketing strategy where customers are encouraged to order food by going to the caterer’s physical store rather than online.

Imagine how many people are choosing the convenient and practical way to serve food to their guests to celebrate life milestones. Statistics show that catering services are in demand for the following occasions: weddings, engagements, birthdays, corporate events, graduations, Christmas parties and even funerals. There is also a growing need for food services at trade shows and conferences around the world.

Reports show that the money spent on food service depends mainly on how much corporate clients or individual consumers can spend for certain occasions. This is why caterers often offer various packages and sometimes even create meals to suit the most limited budget.

Being able to cater to large groups opens up a number of catering opportunities for them, so it is rare for them to turn down any offer, deal or invitation. However, while the demand still exists, customers are less likely to request catering services during uncertain economic times.

According to Koncept Analytics market research, the top 3 factors driving the growing demand for contract and freelance catering services are people’s need for personalized food ordering, the rise of the middle class, and the continued use of the digital technology.
