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://a-moz.groupbuyseo.org/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

JavaScript page loader - SEO impact
Hello all,
Technical SEO | | Lvet
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
Cheers

Can a CMS affect SEO?
As the title really, I run www.specialistpaintsonline.co.uk and 6 months ago when I first got it it had bad links which google had put a penalty against it so losts it value. However the penalty was lift in Sept, the site corresponds to all guidelines and seo work has been done and constantly monitored. the issue I have is sales and visits have not gone up, we are failing fast and running on 2 or 3 sales a month isn't enough to cover any sort of cost let alone wages. hence my question can the cms have anything to do with it? Im at a loss and go grey any help or advice would be great. thanks in advance.

Are Collapsible DIV's SEO-Friendly?
When I have a long article about a single topic with sub-topics I can make it user friendlier when I limit the text and hide text just showing the next headlines, by using expandable-collapsible div's. My doubt is if Google is really able to read onclick textlinks (with javaScript) or if it could be "seen" as hidden text? I think I read in the SEOmoz Users Guide, that all javaScript "manipulated" contend will not be crawled. So from SEOmoz's Point of View I should better make use of old school named anchors and a side-navigation to jump to the sub-topics? (I had a similar question in my post before, but I did not use the perfect terms to describe what I really wanted. Also my text is not too long (<1000 Words) that I should use pagination with rel="next" and rel="prev" attributes.) THANKS for every answer 🙂

Do rss feeds help seo?
If we put relevant RSS feeds on a site, will it help the SEO value? Years ago, I shied away from RSS feeds because they slowed the site down and I didn't like relying on them. However, the past couple years, the Internet has become better, especially in Alaska.

How to SEO a Website Built off Godaddy?
I have a client whose website is built off Godaddy services. I know Godaddy is not the right choice for building a website, but what's done is done. The client has already bought the Godaddy services and there's no way I can tell him to go rebuild his website before we could optimize it for SEO. I'm already facing a lot of challenges while optimizing on-page elements. When I wanted to verify the ownership for Google Analytics and Webmaster Tool via his Godaddy account. the process failed many times. it looks like Godaddy is using some kind of caching not allowing us to modify the codes. For example, I'd applied the site verification codes for Webmasters Tool 48 hours ago, and the metatag for google site verification is not yet updated in the frontend. It's quite frustrating. What would you suggest?

Changing DNS -- SEO implications?
Hey Moz, We're migrating an old site on an old server over to a new server/DNS. The plan is to keep the same URL structure and reuse our existing URL's. As long as we make minimal changes to each page's content, we should be able to update our DNS entry and get all the pages recreated and assigned to their correct URLs without any reduction in SEO rankings. Is this correct? This site gets a lot of organic traffic and ranks highly on some challenging keywords, so it's key that we retain our rankings as much as possible. I've read that it's wise to lower the DNS time-to-live to one hour, about a day before the move, to help Google crawl the DNS a little quicker. Are there any other recommendations you guys can offer or past experiences?

Where should a knowledge base be hosted for max. SEO benefit?
A client would like to set up a knowledge base to work in conjunction with their website and we are tossing up whether to go with a hosted solution (and therefore set up as a subdomain) or find a solution that we host on the clients domain (which will presumably have more SEO benefit). We are leaning towards the latter (although are mindful that we need to balance the client’s desire for a quality KB solution). Appreciate your feedback.
