Social sharing and comments: If you’re on social media, you’re probably familiar with sharing and commenting. Social shares and comments are good indicators of how relevant your content is with your target audience. If a viewer watches your video and takes the time to share it with their network, you probably created a great piece of content. Social shares are also important because the more times your video is shared, the more it’ll be viewed. If your goal is to reach to reach a lot of people, social shares is good metric to track.
TikTok reached 500 million users in July, and had other notable achievements this year such as being the most-downloaded non-game app worldwide in Apple's App Store in Q1, the South China Morning Post reported. It surpassed Facebook, Instagram, Snapchat and YouTube in downloads in September, according to data compiled by researcher SensorTower, pointing to the explosive growth in the space and potential for marketers. TikTok's user base is bigger than Twitter's audience of 336 million and Snapchat's 186 million, presenting a possible way for advertisers to reach young audiences on mobile as the platform steps up its advertising capabilities.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Search engines reward you when sites link to yours – they assume that your site must be valuable and you’ll rank higher in search results. And the higher the “rank” of the sites that link to you, the more they count in your own ranking. You want links from popular industry authorities, recognized directories, and reputable companies and organizations.
One of the best ways to improve the look of your video is to include b-roll. B-roll is the supplementary footage included as a cutaway. This might include shots of a customer service rep talking on a phone, a designer editing your website, visuals of your office, or even screenshots of your product. The key with b-roll is to make sure each and every piece enhances the story.
YouTube research shows that users spend a significant amount of time watching review videos that share people’s personal and unique experiences with a company or brand. Studies show these types of videos are more “trustworthy” and benefi­cial when they feel personable and honest, as opposed to professional and polished. This can help to build trust with your target audience and boost engagement through likes, shares, and comments.

Another part of SEM is social media marketing (SMM). SMM is a type of marketing that involves exploiting social media to influence consumers that one company’s products and/or services are valuable.[22] Some of the latest theoretical advances include search engine marketing management (SEMM). SEMM relates to activities including SEO but focuses on return on investment (ROI) management instead of relevant traffic building (as is the case of mainstream SEO). SEMM also integrates organic SEO, trying to achieve top ranking without using paid means to achieve it, and pay per click SEO. For example, some of the attention is placed on the web page layout design and how content and information is displayed to the website visitor. SEO & SEM are two pillars of one marketing job and they both run side by side to produce much better results than focusing on only one pillar.
