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

Are on-site content carousel bad for SEO?
Hi, I didn't find an answer to my question in the Forum. I attached an example of content carousel, this is what I'm talking about. I understand that Google has no problem anymore with tabbed contents and accordeons (collapsible contents). But now I'm wondering about textual carousels. I'm not talking about an image slider, I'm talking about texts. Is text carousel harder to read for Google than plain text or tabs? Of course, i'm not talking about a carousel using Flash. Let's say the code is proper... Thanks for your help. spfra5

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?

CSS user select and any potential affect on SEO
Hi everyone and thank you in advance for your helpful comments. We have a client who is concerned about copying of content from their site because it has happened a few times in the last few years. We have explained that the content is essentially publicly available and that using the CSS selector user-select to prevent selection of text will really only prevent the technically limited users from working out how to get the text. He is happy that it will at least stop some people. So the question is would there be any way that this would have an affect on SEO? We would make an assumption that it doesnt but putting it out there for some feedback. Cheers Eddie

How Does Dynamic Content for a Specific URL Impact SEO?
Example URL: http://www.sja.ca/English/Community-Services/Pages/Therapy Dog Services/default.aspx The above page is generated dynamically depending on what province the visitor visits from. For example, a visitor from BC would see something quite different than a visitor from Nova Scotia; the intent is that the information shown should be relevant to the user of that province. How does this effect SEO? How (or from what location) does Googlebot decide to crawl the page? I have considered a subdirectory for each province, though that comes with its challenges as well. One such challenge is duplicate content when different provinces may have the same information for some pages. Any suggestions for this?

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

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?
