Hello,
Thank you for contacting Rank Math for help with the “image headers expire” warning on your website.
Please may you share the URL of the affected website so we can check that the “image headers expire” module has been installed correctly. You can add the website URL in the designated sensitive data area to keep it private.
Looking forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
As you mentioned that you already have the rules mentioned in this KB in your .htaccess, please try adding the following line to the .htaccess file, as I can see that in your site, you mostly have images with webp format:
ExpiresByType image/webp “access 1 year”
Or you can directly paste the following one by replacing the current one to see if that works for you:
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/html "access 1 month"
ExpiresByType text/css "access 1 month"
ExpiresByType text/javascript "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType image/svg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/webp "access 1 year"
ExpiresByType application/pdf "access 1 month"
ExpiresByType application/javascript "access 1 month"
ExpiresByType application/x-javascript "access 1 month"
ExpiresByType application/xhtml+xml "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 4 days"
</IfModule>
Once done, flush the analysis cache by heading over to Rank Math > Status & Tools > Database tools > Clear SEO Analyzer and re-run the SEO Analysis.
Let us know how it goes. Looking forward to helping you.
Thank you.
Hi Dear Md. Sakib Khandaker,
I had tested what you said, before starting to open a ticket here.
You know, as I said earlier, for me this code generated automatically by “Litespeed Cache Plugin” in my .htaccess file. When I was reading your guide, I examined my code thoroughly. It had the line you said like this:
ExpiresByType image/webp A31557600
But, just to ensure, I did what you said again:
I removed the above line from my code, and inserted your line (ExpiresByType image/webp “access plus 1 year”), then flush the analysis cache and re-run the SEO Analysis, still no success.
You know, I’m sure that I hadn’t this warning before (My SEO Analysis Score was 100/100) , and I didn’t change anything relating to this code, but then suddenly …
That’s weird, what should I do now?
Thanks again in advance for your help.
Hello,
I just heard back from the internal team that Rank Math supports only the image formats that supported by WordPress. I’m sorry for the confusion earlier.
Also, our tests look for the first image on the page and see if it has the expires headers in the HTTP response. As your site’s first image is in the webp format, the webp format is not being analyzed by Rank Math, and you’re encountering the error on SEO Analysis.
In this case, you can simply ignore the warning, since this won’t have an impact on your SEO/rankings.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
Hi,
As I know, webp format is supported by WordPress, so as you said, Rank Math must support it too? no?
Anyway, so if I change the format of first image in my site to jpeg, that will be ok? and how can I find the first image in my site? is it my logo?
Finally, do Rank Math have any plan to analyze webp format in future updates?
Thank you for helping me to understand what was the problem.
Sincerely.
Hello,
As I know, webp format is supported by WordPress, so as you said, Rank Math must support it too? no?
WordPress basically supports the image formats .jpg, .jpeg, .png, .gif, .ico. Hence, Rank Math doesn’t analyze the webp format yet.
Anyway, so if I change the format of first image in my site to jpeg, that will be ok? and how can I find the first image in my site? is it my logo?
Changing the first image might work in this case. To look for the first image, you can search for first <img tag in your page source.
Finally, do Rank Math have any plan to analyze webp format in future updates?
I’ve shared the suggestion to the internal team and we’ll see if there’s something we can do about it.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
