Great. After explaining the different ways that you can do online marketing, now I'm going to explain which kind of tools you can use in each different way of online marketing. Do you remember that in the past video I said, you need to use the tools that I'm going to propose to you to solve and how to build your startup? Here I say the same. I will explain which are the most well-known and the most effective ways to do each one of the online marketing areas that I'm going to explain. The first one is online search. The best way to acquire customers using online search in SEM is Google AdWords. Google AdWords is a service that provides Google where you can buy the words that you want to use when someone is searching online, and you want to appear. You have seen in Google those first links that they are sponsored ads, or sponsored links, or directly advertising. You can buy some words in Google using Google AdWords. And that is the most effective way to appear in the first results. You need to take care because you need to check your budget each day, and you need to check which words are being useful for your business. What does it mean? Does it mean that, for example, if you are trying to sell online legal docs, you're going to buy something like "Buy Legal Docs," "Agreements Online," "Legal Documents online" because I have a lot of users? But my question is, but those users are they converting to customers? Do you really think that bring a user is just good or do you want a customer? The most important online service is Google AdWords. You can check online and you can find videos to learn how to use it. The second service that you can use to attract users or customers to your project is Bing. It's a service provided by Microsoft to do the same like Google AdWords but in Bing search. The next type of online marketing that you can use is SEO. I love SEO. It's Search Engine Optimization. What's this? I have explained that it is a free way to appear in the first results of a search engine. And how you can know with which words you must appear? I recommend different service. The first one is use Google Trends. Google Trends permit you to compare two words and see which word is more used. For example, if you are looking for attorney in San Francisco, you want to check if the people use attorney in San Francisco, lawyer in San Francisco, law firm in San Francisco and you can check which of those words is more used. Also, you can use services like Moz.com or Semrush. These services are very very useful because you can learn from your competitors which words are they using? Which words are they buying in an online search marketing? And also, you can use for example Google Analytics. When you already have your project, when you already have your website, you can use Google Analytics to plan and to know with which keywords you are acquiring users and with which keywords those users are converting to customers. Then, use Google Analytics to track all the investment that you are doing in a SEM and SEO. The second way to make online marketing is Display Ads. Those image that appear in the newspaper online, for example. You can buy and you can display your ads using Google AdWords, also using Bing by Microsoft, using Criteo, or using YouTube. In YouTube, you also you can put videos. How you can make remarketing? Remember, remarketing is when someone search for a product or a service and then when that people, when that users just move through Internet to different pages, you can follow them with your ads. You can use Google AdWords remarketing service, also you can use Bing for remarketing and Criteo. The third service that you can use online to attract customers, to make online marketing, is Email marketing. And the most well-known and the most recommended service here is MailChimp. You can start for free because it's a freemium model. And you can start the first hundred of users for free using MailChimp to send online emails, to do online email marketing. It's very easy because MailChimp offers you templates. The fourth way to make online marketing is do the marketing in the social networks. And here the most recommended platform will be Facebook. Facebook has evolved amazing its ads service. Five years ago, it was very complicated to put an ad on Facebook but now it's very easy and you can attract customers, and you can attract a lot of users for your service using Facebook. One good thing that has Facebook is that you can target. For example, if you only want people from 40-50 in San Francisco or in Madrid or in Barcelona or in Brazil or whatever, you can target those users. It's a very useful service to show your ads only to the person that you want. Also, you can use Twitter. And the last one that I will recommend are the legal markets online. A legal marketplace online helps law firms, and attorneys, and lawyers to find customers. Those users that are looking online for a lawyer. If you have a law firm, if you are a lawyer and want to acquire new customers, I'd recommend legal marketplaces. And the reason is because you can as specifically explain which practice is your service. You can say, "I only want customers in that specific area." The more relevant tools here are Lawyers.com, Martindale.com, Findlaw.com, Avvo.com, Justia.com and Elabogado.
