For an email signature, what is the “ideal” CDN image hosting provider? [closed]

Email signatures typically have an image of a logo or a profile picture. My question is, what is your recommended image hosting URL/service? Are some URL’s trusted over others?

I am not sure where to host these images hence the question.

I guess some ISP’s and email clients determine the "trustworthiness" of an image URL?

All experience greatly appreciated!

Site rankings tanked after removing 1750 Blog tags

I recently removed 1750 tags from my company’s blog. Many of them were irrelevant or synonyms created by someone who didn’t know how to use tags, some were even misspellings. I removed 1730 of them, removing them from the tag section in WordPress, as well as from the actual article in the QuickEdit section.

I was under the impression this would add to SEO efforts, as many articles detail that, such as this one from Yoast. However, rankings for the keyword "recruitment software" dropped from #17 to #30. Other more niched keywords lost rankings for the homepage altogether, and a blog post appeared there instead (albeit a few ranking spots lower).

I’m worried that removing all those tags have produced 404 errors which have caused the nose-dive in rankings :/, should 301 redirects be created for each lost tag webpage? In the WordPress backend, Yoast was suggesting I do that with their app’s premium version as I was deleting. Any ideas would be much appreciated, as you can imagine the fright and dread I got from losing rankings like that overnight.

FYI, it has been a week since the fall in rankings, fluctuations seem to have slowed.

The best practice of Article / Web 2.0 / Blog submission in off-page SEO?

I am planning for my e-commerce new project. And I am stuck at the best practices of off-page submission for Articles / Web 2.0 / Blogs. I have some questions in my mind which are as follows:

  1. Can I submit the same Article / Post (or content) in different off-page submission sites?
  2. How can I measure that which off-page submission sites are important or useful (like any terms DA, PA or DR).
  3. And How much content submission will effect my domain progress or good link equity?

Can a webpage differ in content if ‘http’ is changed to ‘https’ or if ‘www.’ is added after ‘http://’ (or ‘https://’)?

When I use the Python package newspaper3k package and run the code

import newspaper paper = newspaper.build('http://abcnews.com', memoize_articles=False) for url in paper.article_urls():     print(url) 

I get a list of URLs for articles that I can download, in which both these URLs exist

  • http://abcnews.go.com/Health/coronavirus-transferred-animals-humans-scientists-answer/story?id=73055380
  • https://abcnews.go.com/Health/coronavirus-transferred-animals-humans-scientists-answer/story?id=73055380

As can be seen, the only difference between the two URLs is the s in https.

The question is, can the webpage content differ simply because an s is added to http? If I scrape a news source (in this case http://abcnews.com), do I need to download both articles to be sure I don’t miss any article, or are they guaranteed to have the same content so that I can download only one of them?

I have also noticed that some URLs also are duplicated by adding www. after the http:// (or https://). I have the same question here: Can this small change cause the webpage content to differ, and is this something I should take into account or can I simply ignore one of these two URLs?

Transition multiple independent WP sites to one WP multisite on the server with minimal downtime

I currently have three independent WordPress blogs hosted on a single shared server.

The main domain (we’ll call domain-A is sitting in the public_html folder. domain-B and domain-C are separate WP installs residing as subfolders within public_html. Each of the installs is mapped to its own, unique URL.

Here’s the structure of the server:

/public_html     ..core WP files, etc     /domain-B         ...WP install core files     /domain-C         ...WP core... 

I am attempting to set up a WP multisite, incorporating all 3 blogs under domain-A as my main parent site.

My plan is to create the multisite in another subfolder in public_html and once the site is configured, I want to seamlessly – with minimal downtime – swap out the independent sites for the one multisite.

How would I do that?

Here’s what the new server config might look like:

/public_html     ..core WP files, etc     /domain-B         ...WP install core files     /domain-C         ...WP core...     /new_multisite 

Ideally, it would be great if I just had one wp multisite install in the root folder and could remove the other independent installs, e.g:

/public_html     ... wp multisite core files, etc.. 

I read some stuff about configuring my local hosts file on my system to be able to re-route the IP address to a domain URL (still a little fuzzy on some of the details of that) but I don’t see how that helps with a live site and/or a remote server.

Also, is it safe to create a "sandbox" site in a subfolder on the shared server? How can I keep this folder undiscovered or inaccessible? I am considering doing the setup on my local computer using WAMP as a dry run but I’ll still have to contend with uploading it to the live server, testing it, then making the switch from 3 independent blogs to one multisite.

Edit: I’m learning now that .htaccess can be used to control redirects to a subdomain, so theoretically, all requests to the original domain(s) can be redirected to sites/domains within the multisite. Obviously, the specifics of this starts to get a little hairy.

Thanks in advance,

How do you prevent HTML special character coding from displaying on a website?

An article in the Wall Street Journal (wsj.com) displays HTML special character code instead of the actual character, the greater-than sign. Thus, instead of displaying >, the article displays >. This occurs (for me, at least) on Chrome, Firefox, and Safari (all latest versions with cache cleared).

My (limited) understanding is that websites should have the following code in the header:

<meta http-equiv="content-type" content="text/html;charset=utf-8" /> [α] 

The wsj.com site has this code in the header: <meta charset="UTF-8">. Is this the cause of the problem? In other words, if the WSJ site had <meta http-equiv="content-type" content="text/html;charset=utf-8" /> in the header, would we see > instead of &gt;?

The Wall Street Journal article is:

  • Stern, Joanna. "iOS 14 Review: Your iPhone Will Look Completely Different Now, if You Want." Wall Street Journal (16 September 2020).

The article is probably behind a firewall, so here is an image of the sentence as it appears in the article:

Long after the demise of Google Authorship, is it now both valid and viable for a document to include multiple links?

When Google Authorship was very much still a thing several years ago, the conclusion was that it was better not to include more than one <link rel="author"> on any given page.

See:

  • 2012 – How to implement rel="author" on a page with multiple authors?
  • 2013 – Is Google OK with multiple rel="author" links?

Google Authorship is now a distant memory (Mountain View stopped using it several centuries ago in 2016) but I’m concerned that there may still be something invalid or nonsensical about including more than one <link rel="author"> in the <head> of a given document.

My use case involves referencing both an About Page and humans.txt:

<link rel="author" href="https://example.com/about-us/" /> <link rel="author" href="https://example.com/humans.txt" type="text/plain" /> 

Is there anything – I can’t find explicit confirmation – from the WHAT-WG to confirm that this is valid usage?

Or is there a viable alternative to using more than one <link rel="author"> element?

Run Python Functions in frontend [closed]

I know front-end developement with React.js. I want to make a basic web-app where I use some python functions (for example on onClick of buttons etc). These functions would mainly revolve around machine learning (but wont be too complex).

Is there any way to run python functions from React.js apart from ajax queries?

If not, which Python framework should I use to do web development in Python such that I can directly run Python functions as well? I have come across names like Django, Tinkter and Flask but couldn’t figure out what exactly would suit my requirement.
