If SiteNavigationElement is meant for the whole navigation (i.e., a navigation link list), your first example is correct. If SiteNavigationElement is meant for a single navigation entry (i.e., a link in the navigation link list), your second example is correct. I think Schema.org doesn’t unambiguously define which variant is meant, as they only say: A … Read more
You may use external for every link to a different website, no matter if it’s yours or not, if it’s on the same host or not. You may use nofollow for every link that you don’t endorse (for example: search engines shouldn’t assume that it’s a relevant link and should not give any ranking credit … Read more
Normalize your string using canonical decomposition: private static final Pattern NONLATIN = Pattern.compile(“[^\\w-]”); private static final Pattern WHITESPACE = Pattern.compile(“[\\s]”); public static String toSlug(String input) { String nowhitespace = WHITESPACE.matcher(input).replaceAll(“-“); String normalized = Normalizer.normalize(nowhitespace, Form.NFD); String slug = NONLATIN.matcher(normalized).replaceAll(“”); return slug.toLowerCase(Locale.ENGLISH); } This is still a fairly naive process, though. It isn’t going to do … Read more
Put the <noscript> content at the end of your HTML, and then use CSS to position it at the top of the browser window. Google will no longer consider it important. Stack Overflow itself uses this technique – do a View Source on this page and you’ll see a “works best with JavaScript” warning near … Read more
I’m pretty sure anything you’ve seen promoting React as being good for SEO has to do with being able to render the requested page on the server, before sending it to the client. So it will be indexed just like any other static page, as far as search engines are concerned. Server rendering made possible … Read more
The mechanisms you describe (A and CNAME records vs. 301 redirects) are part of two different protocols (DNS and HTTP). A and CNAME records have nothing to do with which site your HTTP server serves for different requests. Let’s look at two different DNS configurations: Configuration 1 (CNAME record) Host | Type | Data —————–+——-+————- … Read more
Tim Berners-Lee (the architect of the WWW) wrote a great article about this subject about 10 years ago. Your example is a bad URL — but not just because it has both an id and a “slug” (the abbreviated, hyphenated form of the page title). Putting the page title into your URL is problematic in … Read more
No, we (Google) won’t see the content behind tabs iff the content under the tab is dynamically generated (i.e. not just hidden). You can also see what we “see” using Fetch as Google in Search Console (former Webmaster Tools); read more about the feature in our post titled Rendering pages with Fetch as Google.
RedirectMatch uses a regular expression that is matched against the URL path. And your regular expression /contact.php just means any URL path that contains /contact.php but not just any URL path that is exactly /contact.php. So use the anchors for the start and end of the string (^ and $): RedirectMatch 301 ^/contact\.php$ /contact-us.php
