Test ways of previewing posts and pages

This page compares ways of previewing pages and posts.

This page uses:

  • the short-code from the plugin wp-link-preview, and
  • a simple embed (you just paste in the full URL)
  • the visual-link-preview plugin
  • the plugin “display-posts”

It uses:

  • a POST from this site which has a featured image,
  • a PAGE from this site which has a featured image,
  • a page from this site which does NOT have a featured image,
  • a post from ANOTHER SITE which has a featured image.

This site uses:

  • Theme Twenty-fourteen
  • The latest Gutenberg WordPress
  • The classic editor plugin

Preview the CO2 page from this site. The page has a featured image.

Use “visual link preview” plugin

  • I left the Visual-link-preview summary blank and hoped the default would be to show the initial text from the page.  This has not happened on the CO2 PAGE.  The authors write they have plans to get the summary from the URL.
  • On the “data form” of the plugin you see the default title, which is the title of the page.  It is very easy to edit it.

 

  • The same has happened for the POST about the plane
  • It looks good even like this without the summary.

Comments about visual link preview plugin

  • I have tried previewing my evidence pages – and it seems to run fast – not the slowness of many embeds on one page.
  • The plugin draws text and the image from the previewed page once, when the website author sets up the preview, not each time the page is opened. This will make it fast.
  • The authors say that search engines see the internal links set up by the plugin.

Use plugin “display-posts”

 

  • CO2 Levels- CO2 levels are rocketing up. The orange line shows how the level of “carbon dioxide in our air” has moved over the last 400,000 years. Before 1950, CO2 levels moved between : lows near 180 parts per million (ppm) during ice ages, and highs near 300 ppm. The CO2 level in 1960 was about 317 … Continue reading CO2 Levels

 


Test plugin wp-link-preview shortcode.

  • This presents well
  • width is too narrow
  • In the excerpt, I had a “-” at first which showed as a “?”. I edited my page to omit the “-“.
  • the plugin has produced a muddle of words at the end of the excerpt “Look at the CO2 levels over ? Continue reading CO2 Levels ?”.
  • There are three links to the URL which is great: image, title and at the bottom.
  • The only input to this plugin, for internal or external links, is the URL.  I think this means plugin reaches out to the URL each time the page is viewed, to draw in an image and text.  This may mean it is slower then a plugin that reaches out only once, when the website author sets up the preview.

Test a simple embed of the same URL.

This embed is beautiful. It shows the image, title, and excerpt.

CO2 Levels


Preview the sea-level page from this site. This page has NO featured image.

Test plugin wp-link-preview shortcode.

  • This is good as it has picked up the first image on the page and shown this. It has not needed a featured image.
  • too narrow
  • the end of the excerpt is again a muddle of words
Sea levels are steadily increasing. This is dangerous as they have the potential to rise by tens of metres and cause wide spread devastation.

Use visual link preview

  • No image as there as no featured image on this page
  • The plugin has not used the image inserted into the page.
  • no summary as I did not enter any and the plugin has not taken text from the page

Test a simple embed of the same URL.

The embed has not shown the image, as there is no featured image.

Sea Level


Preview a newsletter post from this site which has a featured image.

Test plugin wp-link-preview shortcode.

This shows the image and tile of this post, but not an excerpt.

Test a simple embed of the same URL.

This is great. It shows the image, title, and excerpt. (On a website using theme Avada, I had to use CSS code to get the simple embed showing on mobiles with no truncation.)

Climate Action Monaro Newsletter 3 June 2018


Previewing an external post which has a featured image.

The page is the Beyond Zero Emissions “Australia as a renewable energy superpower” post.


Use visual link preview plugin

 

  • I entered the URL and nothing appears by default.  Seems like you have to add the title, an image from your own website media and summary.

Use the plugin wp-link-preview shortcode.

  • This does not show the image
  • Instead of the image it shows the URL which is badly formatted.
  • Too narrow

Try a simple embed.

This does not work here.  The puzzle is that this same embed is still working  on my home page.

WordPress should provide a  FAST preview feature like this within WordPress itself.

This ability to preview other pages or posts from your own website is useful.

For example, I would like to use it on my home page, effortlessly and attractively showing an overview of my key content and linking to it.  And I want to use it in “directory pages”: like:
https://www.feedbackreigns.net/evidence/

Whenever you want to refer to another section of your website, these previews give you an attractive image,  excerpt, and link.

This preview feature would get people using their site in a modular way. You can write one good description of something, particularly getting the first paragraphs to be a good excerpt, and with an attractive image.  Then it is easy to reuse this in the rest of your site.

Embeds

The embeds are beautiful when they work.  However they are slow, so you should not use more than about 3 on one page.  Also, there seem to be extra restrictions on using embeds since the Gutenberg editor.
