Navigating the landscape of YouTube in 2018 required a specific understanding of how the platform's discovery algorithm functioned. Unlike a simple directory, YouTube is a recommendation engine that relies heavily on metadata to categorize and surface content. For creators, selecting the right set of keywords was not just a formality; it was the primary method of signaling to the algorithm what a video was about and to whom it should be suggested.
The Strategic Role of Keywords in 2018
In 2018, keywords served as the bridge between user intent and creator content. The platform was processing millions of hours of video daily, and text-based metadata was the only reliable way to index this content efficiently. The focus that year shifted slightly from sheer volume to relevance. While stuffing the tags field with popular terms was still common, the algorithm had become sophisticated enough to prioritize watch time and viewer satisfaction over misleadingly popular tags. Therefore, the keywords needed to be highly specific to the video's actual content to ensure the right audience was being reached.
On-Page Optimization Fundamentals
Optimizing a channel in 2018 began long the video was published. The channel name itself was a significant ranking factor, often incorporating the primary niche or brand name. Similarly, the handle needed to be memorable and relevant. The "About" section was treated like a mini elevator pitch, where broad industry keywords were essential for appearing in channel searches. Furthermore, the custom URL structure helped solidify the channel's brand identity, making it easier for the algorithm to associate the handle with specific content themes.
Video Title and Description Logic
The video title remained the single most important on-page SEO element. The best practice involved placing the primary keyword within the first 60 characters to ensure it displayed fully in search results. In 2018, titles needed to balance algorithmic optimization with human curiosity, moving slightly away from clickbait toward clarity. The description box required a strategic approach, with the first 150 characters acting as the crucial meta summary. Including keywords naturally in the first two sentences signaled the topic to the algorithm, while the remainder of the text provided context for the transcript and related links.
Technical and Backend Strategies
While visible elements were vital, the backend tags held significant weight in 2018. This field allowed creators to input synonyms and related terms that might not fit naturally in the title. For example, a video about "Chocolate Chip Cookies" could utilize tags like "baking recipe," "dessert tutorial," and "easy home baking" to cover semantic variations. The goal was to capture the long-tail searches users might employ, ensuring the video could appear in slightly different query contexts without keyword repetition.
Primary Keyword: The core term directly related to the video's main topic.
Secondary Keywords: Variations or closely related terms that support the main subject.
Long-Tail Keywords: Specific phrases that indicate user intent, often with lower competition.
Negative Keywords: Terms you exclude to prevent your video from showing for irrelevant searches.
Analyzing the Competitive Landscape
Research was a cornerstone of the 2018 keyword strategy. Creators relied heavily on YouTube's own autocomplete feature to identify popular search queries. By starting to type a topic in the search bar, the platform would generate suggestions based on real user behavior, revealing high-intent keywords. Additionally, analyzing the metadata of successful competitors in the same niche provided insights into which terms were driving traffic. This competitive intelligence was crucial for identifying gaps in the market and finding underserved search queries that a channel could dominate.
