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

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.

1 - Call To Action - Static to a landing page
10 Calculators - Static - These calculators I think are very useful to our users (financial website). So in total 17 total sidebar links, 11 static links, and 6 which change based on the content of the page. Do you think these static links from an SEO perspective can be hurting us? Is there some sort of best practice for sidebar links in regards to quantity as well as static vs non-static? Thanks!0 -
Coming soon SEO
Hi, I was wondering what is the best practice to redirect all the links juice by redirecting all the pages of your website to a coming soon page. The coming soon page will point to the domain.com, not to a subfolder. Should I move the entire website to a subfolder and redirect this folder to the coming soon page? Thanks

ECommerce: Best Practice for expired product pages
I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

Header Tags
Ok so I am writing different pages and the first heading is an H3 just because I wanted to it be a certain size. Then as you see the content, I have an H1 tag. Example page: http://www.oxfordmshomes.net/condos/acadia-court-Oxford-MS you can see that "Acadia First" is the first thing you see on the page and it uses an H3 element. Long story short, my hierarchy is wrong. Does this have any negative effect on my SEO efforts?

First click on SEO redirecting to a competitor site?
I just experienced something VERY odd and wondered if any of you had an idea of what it might be. When I did a search on Google and clicked the top SEO listing I was taken to a competitor of the number 1 listed site i.e. NOT the site I clicked on. When I clicked the back button and clicked it again, I was taken to the correct site. This happened with two different searches and I was taken to two different sites. Could this be a clever/sinister cookie implemented by the competitor; a site I frequent regularly? Could this be malware implemented by an affiliate? Could this be a Google glitch?
