I have setup a hosted site using a mySQl database to store Temperature and Humidity results sent from an ESP32/DHT11. This data is then visualized in a webpage utilizing chart.js to plot the data using a simple line graph.
WordPress 3.0 has introduced the ability to create a Custom Post type. Custom Post types allow you to generate a post which can collect more than just a title and block of text. This example is used for a cat breeder and allow them to list (blog style) the cats theat they have available. By having each of the data fields stored individually you can then, through your theme files, create a custom layout for the content.
SEO is a process of getting a web site listing to the top of the list in a search engine result and thus improving volume or quality of traffic to a web site. The most popular of these search engines are Google, Yahoo, MSN, AOL and ASK.
Most search engines rank a site using many criteria. These criteria include page content (word on the page) , meta data (data stored in the page to explain what the page is about) and also the number of times that other sites link to the site.
