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

An immediate and long-term plan for expired Events?
Hello all, I've spent the past day scouring guides and walkthroughs and advice and Q&As regarding this (including on here), and while I'm pretty confident in my approach to this query, I wanted to crowd source some advice in case I might be way off base. I'll start by saying that Technical SEO is arguably my weakest area, so please bear with me. Anyhoozles, onto the question (and advance apologies for being vague): PROBLEM I'm working on a website that, in part, works with providers of a service to open their own programs/centers. Most programs tend to run their own events, which leads to an influx of Event pages, almost all of which are indexed. At my last count, there were approximately 800 indexed Event pages. The problem? Almost all of these have expired, leading to a little bit of index bloat. THINGS TO CONSIDER A spot check revealed that traffic for each Event occurs for about a two-to-four week period then disappears completely once the Event expires. About half of these indexed Event pages redirect to a new page. So the indexed URL will be /events/name-of-event but will redirect to /state/city/events/name-of-event. QUESTIONS I'M ASKING How do we address all these old events that provide no real value to the user? What should a future process look like to prevent this from happening? MY SOLUTION Step 1: Add a noindex to each of the currently-expired Event pages. Since some of these pages have link equity (one event had 8 unique links pointing to it), I don't want to just 404 all of them, and redirecting them doesn't seem like a good idea since one of the goals is to reduce the number of indexed pages that provide no value to users. Step 2: Remove all of the expired Event pages from the Sitemap and resubmit. This is an ongoing process due to a variety of factors, so we'd wrap this up into a complete sitemap overhaul for the client. We would also be removing the Events from the website so there are not internal links pointing to them. Step 3: Write a rule (well, have their developers write a rule) that automatically adds noindex to each Event page once it's expired. Step 4: Wait for Google to re-crawl the site and hopefully remove the expired Events from its index. Thoughts? I feel like this is the simplest way to get things done quickly while preventing future expired events from being indexed. All of this is part of a bigger project involving the overhaul of the way Events are linked to on the website (since we wouldn't be 404ing them, I would simply suggest that they be removed entirely from all navigation), but ultimately, automating the process once we get this concern cleaned up is the direction I want to go. Thanks. Eager to hear all your thoughts.

Breadcrumbs on Mobile How important are they for SEO?
Due to Poor unsightly look of breadcrumbs and the space it takes up above the fold we only employ breadcrumbs on our desktop version. Breadcrumbs are hidden from view on mobile version. However as mobile first indexing is now in play what technical SEO impacts will this have? one thing that comes to mind is crawling deeper pages where breadcrumbs made them accessible in less than 3 link clicks? But i am unsure now of the impacts of not having breadcrumbs visible for mobile version of our site.

Any SEO benefits of adding a Glossary to our website?
Hi all, I manage a website for a software company. Many terms can be quite tricky so it would be nice to add a Glossary page. Other than that, I have 2 questions: 1. What would be the SEO benefits? 2. How would you suggest to implement this glossary so we can get as much SEO benefit as possible (for example how would we link, where would we place the glossary in the terms of the sitemap, etc.). Any advice appreciated! Katarina

Loading images below the fold? Impact on SEO
I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

SEO value of InDesign pages?
Hi there, my company is exploring creating an online magazine built with Adobe's InDesign toolset. If we proceeded with this, could we make these pages "as spiderable" as normal html/css webpages? Or are we limited to them being less spiderable, or not at all spiderable?

International Seo - Canada
Our organization is currently only operating in the USA but will soon be entering the Canadian market. We did a lot of research and decided that for our needs it would be best to use a subfolder for Canada. Initially we will be targeting the english speaking community but eventually we will want to expand to the french speaking Canadians as well. The question is - is there a preferred version in setting up the subfolders: www.website.org/ca/ -- default will be english www.website.org/ca/fr/ - french www.website.org/en-ca/ - english www.website.org/fr-ca/ - french www.website.org/ca/en/ -english www.website.org/ca/fr/ - french Thanks

Should WordPress themes be hard coded for better SEO?
In the interests of making my site faster I have recently come across the suggestion of removing unwanted PHP from my WooThemes WordPress theme. The suggestion is to hard code the choices I have made in the WordPress template to reduce on database calls. Has anyone actually done this to their WordPress theme before and seen any measurable results?

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.
