Search Engine Optimization (SEO) is used to describe the activities that help a website improve their rankings in the Maps and Organic sections of the Search Engine Results Page (SERP)
Content is by far the most important on-site metric. The way your content is structured, quality of copy, and the voice it is written are all critical for search engines, user experience, and conversions.
The method in which you outline your content and title tags. User experience is improved when you can easily identify titles of content, and the structure of your website also informs search engines of the relevancy and authority of your content.
The speed at which a site loads on both desktop and mobile is a ranking signal. Also, websites that don’t have responsive designs for mobile users will be penalized in rankings.
There’s a lot of other items ranging from moderate to low importance. It’s like making dinner. If you concentrate on the big stuff while remembering the fine details, you’ll have an amazing 5 star dinner. If you flake out and ignore the details, it’s a ruined NY strip.
