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

Mozbar sees the 301, but no other header checker does
Ok, why does Mozbar see this 301 redirect, but no other checker can? Original URL: http://www.horizon-bcbsnj.com Current URL: http://www.horizonblue.com/ The dev company uses meta refreshes set to zero (html), javascript redirects (randomly), and 301 redirects (asp) that can't be verified with any other header cheker other than Mozbar. Is mozbar correct and the other checkers wrong? Or is mozbar "special" and the search engine bots do not see the 301 at all just like Rexswain, internetmarketingninjas, SEObook, webconfs, etc don't recognize the 301 either? They all say 200 OK.

Does bait and switch redirecting affect SEO?
Yeah, the question might be an odd one, but I'm new to SEO. Currently we've been considering creating links to certain pages on our site that instantly redirect to a landing page like this (referring to it as bait and switch redirecting): http://www.ecornell.com/certificate-programs/human-resources-management-training/advanced-certificate-in-strategic-hr-management/crt/ILRASHRC1/?lp=http://info.ecornell.com/executive-certificate-in-hr-leadership%3Fls=xxx%26of=xxx This essentially causes the user to "hop" from the content page directly to the landing page. Now, the content page is indexed otherwise, so I'm wondering if time on page (which is basically 0) or anything else might affect page rank. Also, if this is something we shouldn't do, that'd be great to know too. It feels sort of dirty, but I can't find any resources telling me it's bad, or how it would affect pagerank. I've read about pagejacking, but this doesn't seem to fall into the same category. Thanks! Alan

Is there SEO value in having images referenced on other sites?
We use Amazon to host our assets (images, videos, PDFs, etc). These assets can be used across multiple sites we own and we reference them appropriately via our CMS. example asset URL: https://s3.amazonaws.com/lawgical/assets/data/539/original.png We have an infographic we recently distributed that is hosted on Amazon. Obviously we want any link value to go back to our primary URL where we laid out the infographic, however some of the infographic sites are just referencing the above source image URL. Are we losing SEO / link value by not have the infographic hosted on our domain? Do search engines count these image references as a "link"? For your reference...

What are your best tips for SEO on a shopping cart?
So, I am working on a shopping cart platform (X-Cart) and so far don't like it. Also, the web designer is not someone I've worked with before and he is understandably conservative about access--which limits what I can and cannot do from the back end. One of the things I like to do is include text for the search engines. However, based on conversion, etc., I think the product images on a landing page (main brand info with specific products that show up) should show up first to move toward conversion first. I am thinking of adding the text below the product images on the brand pages so the viewer sees the products first while still keeping the content seo. My practice is to use between 300-350 words minimum on a page. Just wondering what best practices you have for a shopping cart. Care to share? Any tips or hints? Thoughts on what I might do that would be most effective? As always, thanks in advance for your sage advice!
