html – Change rel = "noopener noreferrer" to rel = & # 39; noopener noreferrer & # 39; (single quote)

I use a carousel plugin to display images, when I click on an image, it opens a lightbox with the image and the caption (text) below. But when I want to add HTML to the caption, it only works if I use single quotes on the HTML. But when I add


WordPress automatically adds

    rel="noopener noreferrer" 

which is a double quote and does not work on the lightbox. Is it possible to make this single quote and would it still be safe to use a single quote on rel = "noopener noreferrer".

Thank you.

views – rel = "prev" link and rel = "next" link

In my opinion, I want to add a token for the previous page and the next page, but it does not exist, even if the Token module is installed.

In Drupal 7, I used "Clean Pagination" but there is no stable version of Drupal 8. The version is under development and there is a problem that has not yet been corrected.

The module is maintained minimally only receives maintenance patches.

rel – Is there an effective way to report the informational relationship of a web page with multiple social media accounts?

in the of each article page on a given website, I would like to indicate a relationship between that article page and many social media accounts.

At the very least, as much as possible, I would each web page based on an article on social networks represents:

  • the brand of the site
  • the brand of the article publisher
  • the author of the article

It should be noted that:

  • the site is always the same
  • the publisher-contributor sometimes changes
  • the author-contributor changes often

For example. I understand that a classic link to a Twitter account looks like this:

which is great, but given that (I just learned) rel="me" is the XFN equivalent of rel="author", I conclude that this is an appropriate form to be used only to identify the author-contributor.

So what should I use for the publisher-contributor and for the website itself?


For the website's Twitter account, can I (possibly?) Use rel="alternate" where should i use rel="(something else)"?

I first believed that I could not use rel="author" or rel="publisher" to link to social media accounts because I was already using these rel attributes to express relationships with specific web pages.

But now it comes to my mind that I could use rel="publisher" more than once, like this:


How should i approach -a web document on three separate Twitter accounts?


I note that I can use the following:

  • Website:
  • Author:

But it's still only two out of three.

Additionally, it is specific to Twitter and I am looking for something that can apply to any social media platform (Facebook, LinkedIn, etc.).

sitemap – Is there an SEO or pagerank advantage in grouping (rel = "alternative") multilingual websites (using multiple domains) together?

I am building this website which will be multi-region / multi-language.

And for that, Google suggests the following:

enter description of image here

Since, my domain will have to change according to the language of the country, I will have to go there with Option 1.

A country-specific area.



Since they all have different domains, if I don't let Google know that this is the same website, they will all be treated as unique and unique websites.

Google suggests "grouping" them using one of these 3 options:

enter description of image here

If I do, I will use the Sitemap option.

But my question is:

What do I gain by letting Google know that all of these websites are identical, but in different languages? What will be different if I let Google think that these are unique and separate websites?

Do I need to gain SEO or pagerank by doing this?

I mean, what if I get a lot of traffic to my website in English Does it benefit my other languages ​​in other areas?

meta tags – Is it legitimate that rel prev / next links indicate a circular sequence of pages?

First of all, Yes, Google no longer takes note of rel prev / next and has not (officially) done so for almost a year. Google is officially discouraged rel prev / next as an exploration / indexing factor on March 21, 2019:

Unofficially, Google has stopped taking note of rel prev / next several years before that.

But, as with any web document meta-information, simply because Google doesn’t use rel prev / next, does not mean that it no longer represents useful information about the library.

In fact, Google itself even points this out:

rel prev / next may in particular:

  • help accessibility
  • represent a resource pre-fetching advice to mariners.

So here I am, a year after the official announcement still using rel prev / next perfectly happy to create a chain of product pages that each show and discuss one of a set of related products.

To date, I have used rel prev / next to indicate a straight line of product pages from the first product page to the last product page:

Product Page 1 ==> Product Page 2 ==> Product Page 3

This is it.


  • Product Page 1 has no ; and
  • Product Page 3 has no

But would there be something absurd and / or illegitimate to give Product Page 3 a pointing to Product Page 1 and vice versa?

for example. Product 3 ==> Product 1 ==> Product 2 ==> Product 3 ==> Product 1

I would love to implement it, but first I want to verify that creating a circular sequence of pages is not, in principle, an abuse of pagination, in some way so.

Do these monads on Rel compose?

$ Rel $ is the category of sets and relationships.

The cyclical list monad, $ mathcal {Cy} = (Cy, mu_c, eta_c) $ is defined as follows:

$ Cy: Rel $ Rel $ rightarrow,
such as, $ Cy (X) $ All cyclic lists in the set X. A cyclic list is similar to a list, except that each element points to the next element, and that each element has exactly one predecessor pointed in the list. The list thus forms a cycle or a circle.
$ mu_c: Cy cdot Cy rightarrow Cy $
so that a cyclic list of cyclic lists maps all the cyclic lists found by decomposing the internal lists in all possible ways and concatenating the resulting flat lists.

We know that multiset is a monad, $ mathcal {Mu} $ sure $ Rel $.

I would like to know if the following composition is also a monad $ Rel $.

$ mathcal {Cy} cdot mathcal {Mu} $

These are cyclic lists of multisets.

Best practices for multilingual websites – Should I list my URLs in each language or use of rel = "substitute" + is hreflang sufficient?

I'm working on the sitemaps of a multilingual website and I have a doubt about the best practice for referencing each language version of a page.

For a bit of background, the website references about 20,000 places with comments and descriptions of the community. The website is available in 5 languages ​​(; …)

For the moment, my site map only refers to English pages and the site map for each page I specify. for each language (as well as English) recommended by Google.

In the Google Search Console, I find that about 75% of the pages with valid coverage are described as "indexed, not submitted in Sitemap", which makes me think that the alternative link with the hreflang attribute not enough to "submit" the page. google to index it.

Do I have to list the pages in the 5 languages ​​of my sitemap and use them as well? on each link?

Google adds new options to rel = NOFOLLOW attribute

When introducing nofollow, Google would ignore links marked this way as a signal to use in our search algorithms. This has now changed. All link attributes [sponsored, UGC, and nofollow] are treated as indications of which links to consider or exclude in the search.

seo – Google Custom Search showing redirection URLs to external links despite rel = "nofollow noopener" on these links

I have a website that contains a list of all the businesses in my area. They all have a profile page that can include a website URL or Facebook.

I've added rel = "nofollow noopener" to all the external links, but it seems that it does not work and that Google always indexes the redirector. When I search this in Google: website: I still see Facebook links, etc.

I did not define this at the beginning of the website, but I made this change a few months ago.

What's wrong?
