SEO is all about searching for the best keywords and using the right techniques so that people who are searching for anything related to your work will come to your website and can see what you are doing. If you are working as digital marketing agency then SEO will be your backbone because you have to reach more people in order to make your client successful and you can do that with the help of SEO. In this situation you can learn about it as well or you can hire another SEO company to work with you and you have to give some commission to them when you get any project.
When you are using that for the digital marketing then it will well help you in determining that where your website should be ranked and how you can rank there. You need to do a lot of research in this regard and then you will reach to your goals easily. If you have an agency then you need to get a team of workers who will do the research every day and provide you good results which your company needed.
When you are looking for more clients in order to earn more then you have to rank your website or your page according to some keywords and again SEO will help you in this and you can search the keywords which people are searching the most and then you have to select the words which do not have too much competition in that so you can get ranked on the basis of these keywords. If the competition is too much then there are lesser chances for you to get ranked on them so you have to select the keywords carefully.
You will see some of the websites are ranked on more than one keyword and you can do that too but for that you have to be sure about the keywords you are using and how you are using them because stuffing of keywords in your articles will not rank your website instead it will de-rank as Google will not like websites like this so you have to avoid doing this while writing an article on your website also you have to proof read when you are getting the work done by some other writers before uploading.
