Are Expires Headers Detrimental to SEO Health?
-
My dev was looking into Expires Headers to increase speed, but she don't know the ramifications behind them for SEO. What I found online is really old: https://moz.com/blog/expires-headers-for-seo-why-you-should-think-twice-before-using-them
What do SEOs think?
Thanks in advance!

The best way to use expires headers for SEO is to set them to a reasonable value that will balance the need for caching with the need for search engines to crawl your website. A good rule of thumb is to set expires headers for static files, such as images, CSS, and JavaScript, to a long period of time, such as a year. For dynamic content, such as blog posts and product pages, you can set expires headers to a shorter period of time, such as a week or a month. -
No, Expires headers are not detrimental to SEO health. In fact, they can improve your SEO health by increasing your website's loading speed. When a browser loads a web page, it checks the Expires header for each resource on the page to see if it has a cached copy.
If it does, the browser will use the cached copy instead of downloading the resource from the server. This can save a significant amount of time, especially for visitors who are returning to your website.

No, Expires headers are not detrimental to SEO health. In fact, they can have a positive impact on website performance and user experience, which can indirectly affect SEO.
Expires headers are used to instruct the browser to cache specific resources, such as images, stylesheets, and scripts, for a certain period of time. This can significantly reduce page load time and improve website performance, which can in turn improve user experience and engagement.
When users have a good experience on your site, they are more likely to stay longer, share your content, and return in the future. These positive user signals can indirectly impact your SEO rankings by signaling to search engines that your site is valuable and relevant to users.
Therefore, using Expires headers can actually be beneficial to your site's SEO health, as long as they are implemented correctly and not set for too long of a period.

Odchudzanie to proces, który wymaga czasu, cierpliwości i determinacji. Oto kilka ogólnych wskazówek, jak zacząć odchudzanie:Określ cel: Określ, ile chcesz schudnąć i w jakim czasie. Upewnij się, że twoje cele są realistyczne i osiągalne.
Stwórz plan: Stwórz plan żywieniowy i harmonogram treningów. Plan powinien zawierać zdrowe, zbilansowane posiłki i regularną aktywność fizyczną.
Jedz zdrowo: Zdrowe jedzenie to klucz do utraty wagi. Unikaj przetworzonej żywności, fast foodów, słodyczy i napojów gazowanych. Zamiast tego jedz świeże warzywa i owoce, chude białka (np. kurczaka, ryby), pełnoziarniste produkty zbożowe i tłuszcze roślinne (np. awokado, oliwki, orzechy).
Ogranicz spożycie kalorii: Jedzenie mniej kalorii niż potrzebujesz jest kluczowe dla utraty wagi. Skonsultuj się ze specjalistą ds. żywienia, aby określić swoje indywidualne zapotrzebowanie kaloryczne.
Regularna aktywność fizyczna: Ćwicz regularnie, najlepiej co najmniej 30 minut dziennie. Wybierz aktywności, które lubisz, np. bieganie, jazda na rowerze, pływanie, fitness.
Monitoruj postępy: Monitoruj swoje postępy, np. wagę, obwód talii i bioder, i dostosowuj swój plan w razie potrzeby.
Bądź cierpliwy: Odchudzanie to długoterminowy proces. Bądź cierpliwy i nie zniechęcaj się, jeśli wyniki nie są natychmiastowe.
Pamiętaj, że przed rozpoczęciem jakiejkolwiek diety lub programu odchudzania warto skonsultować się ze specjalistą ds. żywienia lub lekarzem.

Hi Dana,
Expires headers and other caching headers can help improve site performance (as you said), and that will be a good thing for SEO. There is no reason to be concerned - they are common headers and there isn't much they could do to have any negative impact on SEO.
Good luck!
Tom

SEO + Structured Data for Metered Paywall
I have a site that will have 90% of the content behind a metered paywall. So all content is accessible in a metered way. All users who aren't logged in will have access to 3 articles (of any kind) in a 30 day period. If they try to access more in a 30 day period they will hit a paywall. I was reading this article here on how to handle structured data with Google for content behind a paywall: https://www.searchenginejournal.com/paywalls-seo-strategy/311359/However, the content is not ALWAYS behind a paywall, since it is metered. So if a new user comes to the site, they can see the article (regardless of what it is). Is there a different way to handle content that will be SOMETIMES behind a paywall bc of a metered strategy? Theoretically I want 100% of the content indexed and accessible in SERPs, it will just be accessible depending on the user's history (cookies) with the site. I hope that makes sense.

How Does Dynamic Content for a Specific URL Impact SEO?
Example URL: http://www.sja.ca/English/Community-Services/Pages/Therapy Dog Services/default.aspx The above page is generated dynamically depending on what province the visitor visits from. For example, a visitor from BC would see something quite different than a visitor from Nova Scotia; the intent is that the information shown should be relevant to the user of that province. How does this effect SEO? How (or from what location) does Googlebot decide to crawl the page? I have considered a subdirectory for each province, though that comes with its challenges as well. One such challenge is duplicate content when different provinces may have the same information for some pages. Any suggestions for this?

Target: blank. Does it make an SEO difference?
I've notice many sites MOZ included no longer use the target: blank attribute. I think that's what it's called. Basically when a link on your site opens a new tab in the browser as opposed to replacing the browser window you are in. Given that MOZ think of everything, I would love to hear opinions on this.

Expired domain 404 crawl error
I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

Does posting an article on multiple sites hurt seo?
A client of mine creates thought leadership articles and pitches multiple sites to host the article on their site to reach different audiences. The sites that pick it up are places such as AdAge and MarketingProfs and we do get link juice from these sources most of the time. Does having the same article on these sites as well as your own hurt your SEO efforts in any way? Could it be recognized as duplicate content? I know the links are great just wondering if there is any other side effects especially when there are no links provided! Thank you!
