An SEO meta description is a brief description of content found on a web page. The meta description is shown to users in search engine results pages to help them decide which search result to click on. Meta descriptions are not a ranking factor in the eyes of a search engine, but they can influence how many people click on a result -- which directly affects the result's organic ranking.
Google knows who links to you, the “quality” of those links, and whom you link to. These – and other factors – help ultimately determine where a page on your site ranks. To make it more confusing – the page that ranks on your site might not be the page you want to rank, or even the page that determines your rankings for this term. Once Google has worked out your domain authority – sometimes it seems that the most relevant page on your site Google HAS NO ISSUE with will rank.
The higher the search volume for a given keyword or keyword phrase, the more work is typically required to achieve higher rankings. This is often referred to as keyword difficulty and occasionally incorporates SERP features; for example, if many SERP features (like featured snippets, knowledge graph, carousels, etc) are clogging up a keyword’s result page, difficulty will increase. Big brands often take up the top 10 results for high-volume keywords, so if you’re just starting out on the web and going after the same keywords, the uphill battle for ranking can take years of effort.
NOTE, in 2019, the HTML title element you choose for your page, may not be what Google chooses to include in your SERP snippet. The search snippet title and description is very much QUERY & DEVICE dependant these days. Google often chooses what it thinks is the most relevant title for your search snippet, and it can use information from your page, or in links to that page, to create a very different SERP snippet title.
Place strategic search phrases on pages. Integrate selected keywords into your website source code and existing content on designated pages. Make sure to apply a suggested guideline of one to three keywords/phrases per content page and add more pages to complete the list. Ensure that related words are used as a natural inclusion of your keywords. It helps the search engines quickly determine what the page is about. A natural approach to this works best. In the past, 100 to 300 words on a page was recommended. Many tests show that pages with 800 to 2,000 words can outperform shorter ones. In the end, the users, the marketplace, content and links will determine the popularity and ranking numbers.
And you’ve got to diversify. Here’s a tongue-twister that’s absolutely true: diversity is a key word in the keyword world. You’re not going to stand out if you find yourself using all of the same keywords as your competitors. Not only should you try new keyword search tools and keep track of the results, but you should feel free to experiment based on your own research – who else uses your keywords? And how do you make yourself stand out? By providing great content that truly answers the questions your prospective customers are asking with their keyword searches.
