One of the ways search engines determine what Google calls “PageRank” is by the number of incoming links, with more weight given to sites with high page-ranks (NB: I will use this term as the generic word to mean how a search engine prioritises how the results are displayed). This has resulted in so-called “link spam” where multiple sites have been created ...

The difference is that, in theory, rel="noreferrer" should not have any SEO impact, while nofollow clearly specifies that the link does not endorse in any way the target URL. nofollow was invented by Google back in 2005 in order to fight comment spam in blogs, any URL appearing in the comment section would not pass PR to the target webpage. rel="noreferrer"...

No such thing as dofollow: The dofollow attribute does NOT EXIST in either rel or meta, this is due to the fact that by default both pages and links are considered dofollow unless you use nofollow. Meta follow is not to be confused with dofollow <meta name="robots" content="noindex, follow"> Despite MASS belief follow and dofollow have nothing in ...

The only time that it is mandatory to use rel="nofollow" on a link is if the link is sponsored. If somebody paid you for the link, or if the link is part of an exchange, Google might penalize your site for NOT including a rel="nofollow" on it. You should also apply nofollow to links that are created by your users without review. Otherwise, they have ...

nofollow will give you granular control to individual external links such as a webpage you don’t necessarily endorse or an internal link you want to prevent bots to access or index such as your members login page. noopener is another property that gives you granular control for webpage performance and security when accessing content on a new window, the ...

The seo experts told us to put rel="nofollow" to all external links. Trying to massage PR (for want of a better term) in this way sounds like a very outdated concept to me. Is e-Commerce any different in this respect? If a site is worth linking to it should be "follow". Generally, rel="nofollow" should only be used on paid-for or untrusted (ie. user-...

Yes, Google still crawl webpages that have noindex tag. But if you have same content on two different webpages and one URL contain noindex tag, while second does not, then you should not worry about it, because out of all duplicate content only one webpage is indexed by Google. Rest of webpages are crawlable but not indexed in Google search result, so that ...

Instead of using rel="nofollow" you should use rel="me" if you're linking to your own social media pages. This allows you to explicitly tell Google that you're not just linking to those pages, but you actually control them. Here's an article with some good insight on the matter. As the article notes: By placing ‘rel=me’ attributes on all your links to ...

Search engines crawlers follow the most restrictive rule. If you use nofollow in your meta tag, no link will be followed. If you use follow in your meta tag, all links will be followed except those with rel="nofollow". So answer to your question is no, meta tag with follow doesn't override individual rel="nofollow". http://googlewebmastercentral.blogspot....

I wouldn't bother and you don't need to look any further then this page to see why. Look at the links to the other StackExchange sites in the footer of this page. It's on every page of every site in the network. If something like this was a problem you can be sure StackExchange, who has direct contact with Google about SEO issues, wouldn't do it.

As Goyllo has already stated, search engine bots will crawl pages that have a noindex meta tag. If you think about it, they need to crawl the page in order to see the noindex meta tag in the first place. (You could use an X-Robots-Tag HTTP response header instead and, in theory, a bot would only need to do a HEAD request in order to see the noindex attribute ...

Rel attribute can contain multiple value. Here is reference link. The value of this attribute is a space-separated list of link types. <a href="http://www.website.com" rel="nofollow"/> <a href="http://www.website.com" rel="me"/> <a href="http://www.website.com" rel="noreferrer"/> So the short form is <a href="http://www.website.com"...

Like I said (dramatically and poorly) in my comments, it is not an acceptable practice. nofollow is designed for webmasters to disavow links on their own website that they do not have editorial control over. The best example of this are blogs with links to the websites of commentors. This was a common source of spam and this allows blogs to allow the users ...

It basically tells the user agent that link should be nofollow'd and also points to an external website. Search engines will know not to pass link juice to the linked-to URL because of the nofollow value. The external value can be used for a variety of things. Often times it is used with JavaScript to automatically provide an icon that indicates the link ...

I don't see why you need to use nofollow here. Google's examples for using nofollow (link) are: Untrusted content Paid links Crawl prioritization However I can see your thinking behind wanting to use them; your sites are similar in subject and structure. However, linking between your own sites is not a violation of Google guidelines and they ...

It's quite likely that the forum software they are using doesn't really support the mechanisms Google and others need to read the AJAX content - as it's not as simple as just "processing the HTML": Making AJAX Applications Crawlable So the idea would be, the site loads the static HTML that is refreshed with a particular frequency (daily/hourly/etc.) that ...

Matt Cutts recommends against it (and in on other posts/videos as well). Plus Stack Overflow is a very different beast then the average website. I wouldn't say that everything they do is appropriate for all sites. And since he also said linking to external sites can be a positive ranking factor, unless you have a very good reason to do it i would not do this ...

I don't think so. Site crawlers don't go inside mailto hrefs.

Most commonly mistaken thing about the 'nofollow' tag is that has nothing to do with not indexing content. I recommend you read the true meaning of nofollow. Also technically email addresses and tel links are internal links so there should be no reason to use a nofollow tag on it. Furthermore, mailto and tel are not pages or links to content in any way. If ...

No this is not good. Google did not intend for nofollow to be used for internal links. It is meant to be used for links that you do not have editorial control over. This is going to hurt you a lot. Your .htaccess code is not adding nofollow to your links. It is not possible for .htaccess to alter your HTML like that. Something else is causing your problem. ...

The tag rel="dofollow" doesn't exist, it does nothing if anybody uses it. Having two rel attributes in the same tag is an error, regardless of their value.

if the linked to page is context appropriate and of a high value wouldn't it be better to allow the passing of pagerank? Quite probably yes. But unfortunately, in the real world, for arbitrary user submitted content on a high traffic website, this is near impossible to guarantee. Trying to manually moderate the outbound links in such fine detail would be ...

rel="noopener" is used so that when a new window is created upon clicking a link, malicious javascript code running in the new window will not access your previous window via the window.opener attribute. rel=noreferrer is used so that when a user clicks on a hyperlink and is transferred to a new location, no referrer information will be leaked to the ...

The practice of hoarding "link juice" isn't a valid practice anymore. Google got wise to the whole "PageRank sculpting" game and amended their algorithm accordingly. Any PR that would have passed via a given link, were it not nofollowed, is effectively thrown away. The only likely exception to this is where users are able to post unmoderated links, for ...

dofollow does not exist so I would infer that the link would be considered as nofollow only.

Yoast answers this very well in this blog post: A better solution would be to add a <meta name="robots" content="noindex, follow"> tag to those search results pages, as it would prevent the search results from rankings but would allow the link “juice” to flow through to the returned posts and pages. Someone will inevitably link to a page you wish ...

Nofollow should be used on untrusted links only. If you are curating these links to the retailers' websites (and it sounds like you are) then there is no reason to use nofollow. If users are posting those links, then you should either use nofollow, or implement a whitelist of sites for which you omit nofollow.

Google does process JavaScript now so, at least for them, this should be effective. But if you want to be sure this works for all search engines you should implement a solution server-side.

Don't worry about small things like this. It's perfectly fine to have both links. Don't nofollow either of the links. With regard to the home page links… Having the logo linked to the homepage provides the conventional link to the root. https://ux.stackexchange.com/questions/81727/why-is-it-standard-for-a-website-logo-to-navigate-to-the-home-page Having ...
