Keywords. Keyword research is the first step to a successful SEO strategy. Those successful with SEO understand what people are searching for when discovering their business in a search engine. These are the keywords they use to drive targeted traffic to their products. Start brainstorming potential keywords, and see how the competition looks by using Google AdWords Keyword Tool. If you notice that some keywords are too competitive in your niche, go with long-tail keywords (between two and five words) which will be easier for you to rank. The longer the keyword, the less competition you will have for that phrase in the engines.
SEO is also about making your search engine result relevant to the user's search query so more people click the result when it is shown in search. In this process, snippets of text and meta data are optimized to ensure your snippet of information is appealing in the context of the search query to obtain a high CTR (click through rate) from search results.
Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
