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

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.

Domain Masking SEO Impact
I hope I am explaining this correctly. If I need to provide any clarity please feel free to ask. We currently use a domain mask on an external platform that points back to our site. We are a non-profit and the external site allows users to create peer-to peer fundraisers that benefit our ministry. Currently we get many meta issues related to this site as well as broken links when fundraisers expire etc. We do not have a need to rank for the information from this site. Is there a way to index these pages so that they are not a part of the search engine site crawls as it relates to our site?

When should a variant be a variant and when should it be a separate product from an SEO POV?
Hi all, We are looking at changing our current e-commerce store to a new platform and in doing so thinking of making some changes to how we list products in sub-categories. We have seen related questions asking about splitting a single product into multiple products to rank for different terms, but we are wondering about combining multiple products into a single product page? The examples we have seen have been about fashion items with variants of colour and size. However, the products we sell have variances that change the appearance, dimensions and technical specification, so we would like to ask the MOZ community if combining products with these variances would still be deemed good practice? We sell wood burning stoves and a good example of a product that we are considering combining is the Scan 85 stove, which is available in eight different configurations: 85-1, 85-2, 85-3 etc. Scan themselves refer to each version as a separate product and they are bought, stocked and sold as separate products. Wood burning stoves like this typically have a firebox in the centre and then design options that can change the top, side, base, door, colour and fuel. In this example, the firebox is the Scan 85 and the variation is the last number, each of which corresponds to a different design option changing both the appearance and dimensions (see attached image). We have them listed as eight different products on our current site, one for each version. Primarily because each option has its own name (albeit 1-digit difference) which when we created the pages we thought that more pages would present us with more ranking opportunity. However, we have since learnt that because these eight pages are all so similar and it is difficult to write unique content about each product (with the 85-1 and 85-2 the only difference between the models are the black trim on the 85-1 and the silver trim on 85-2). Especially as when talking about the firebox itself, how well the fire burns, how controllable it is etc, will be the same for all versions. Likewise, earning backlinks to eight separate pages is also very difficult. Exploring this lead, us to the question, when is a variant a variant and when is it a separate product? Are there hard and fast rules for what defines variants and products? Or does it simply vary from industry to industry product to product, and if so should we be looking at it from a UX or SEO POV, when making that decision? Our hope is that if we combine these eight products into a single high-quality page, it will present us with a greater ranking opportunity for that one page over eight individual pages. We also hope that in doing so will allow us to create a more intuitive UX on a single page with a unique description, more reviews focused on one page and an explanation of the options available, all of which should lead to more conversions. Finally, by creating a better UX and unique detailed description we hope that there is a higher chance of us earning product level backlinks then we do with eight lower quality pages. One of the issues in creating a single product page for all the variants is the sub-category/results pages, as we would be removing eight simple products and replacing them with one complex product. We have questions over how this would work from a filter/facet level whereby when you apply a filter there is an expectation that the image shown will match the criteria, so if we filter for stoves with a silver trim for example, there is an expectation to only see stoves that have a silver trim in the results. When you have separate product pages you have separate listings which makes this easier to only bring back the models matching the criteria. However, when you have a single page this is more complex as you will need a default image for non-filtered results and then the ability to assign an image to lots of different attributes so that the correct image is always shown that matches the criteria selected. All of which we have been assured is do-able but adds an extra level of complexity to the process from an admin side. The alternative to doing this would be to create eight simple/child products and link them to one configurable/parent product. We could them list the simple products into the results pages and have them all linking back to the main configurable product which could load with the options of the simple product that was selected. From an SEO POV this brings in some more work, redirecting each page to the parent, but ultimately this could provide a better UX and might be the better solution. Has anyone got any experience in doing either of these options before? Both options above with affect the number of products we have available, so does the number of products in a sub-category effect the ability for that category page to rank? We currently have around 500 products in our wood burning stoves category, with perhaps an additional 300 to add. If we go down the combining into a single product page route this will reduce the number of products by around a third. If we keep all the simple/child products, then this will stay around the same. So, have we missed something obvious? Is there a glaring issue that we have overlooked from an SEO point of view as well as from the customer experience? We would appreciate your thoughts on this. Thanks, Reece scan85-1.jpg

How do you build your pre-sales seo audit
Hello Moz community, I'd like to know if you build "pre-sales seo audit" when selling your services to a prospect.

If you know ressources i should read as regards to mini seo audit / pre-sales seo audit just paste the link 🙂 Thanks for your answers

Changing menus regularly - will this impact SEO
We are working on an internal project, where the website owner is thinking of making regular changes to one or two items on the top level menu. Assuming they redirect the original pages or navigate to them in other ways, is there any other impact on SEO to changing the menu structure? I assume they'd submit new sitemaps after each change. Many thanks Fiona

Does an subdomain hosted offsite provide SEO value
We have a job board hosted through an applicant processing system which we've setup as a subdomain (jobs.ourcompany.com), most of the assets are hosted on our primary domain (ourcompany.com). My question is does having it hosted offsite provide any value? Do we get credit for that content being shared and distributed on the web or does the applicant processing system? As I see it the options are (correct me if I'm wrong): Host the job listings on our primary domain (ourcompany.com/jobs) and have it point to the application on the subdomain. Advertise the job listings pointing to the primary domain on the paid sites. The free job listing sites will automatically point to the sub-domain because the applicant processing system automatically submits them. Host the job listings entirely on the sub-domain applicant tracking system and link to it from our primary site navigation. Advertise the job listings to the sub-domain so that both free and paid point to the same place. Obviously the second one would be much easier just not sure on the technical side of our website getting credit by search engines as the one who has produced the content.
