SITEMAP - Does <changefreq>and <image:title>have any apreciable effect?</image:title></changefreq>

Hi everyone.

It was hard to find some actual evidence that some of the atributes to be declared in a sitemap have some real impact.
Particularly, im interested in these two: <changefreq></changefreq> and**image:title</image:title>**

I've used them in a few cases just to check their effect and couldnt see any.
Do you have any experience with these? Or any other atribute that might be helpful, in order to create a more accurate and effective sitemap?

Also, this could be a great topic to create a new Moz Blog post, the one about sitemap is 8years old.

My sitemap file has them but only because Screaming Frog and WordPress include that information when they generate the sitemap.

Reading the Google forum, there is a reply from John Mueller from 2014 that he specifically says change frequency and priority do not affect ranking of URL's once they are indexed

He also states that last mod date is good for Google to know.

We all know that you can take things said by Google with a grain of salt, but this is also an instance where it is specifically stated so I would tend to believe it to be true.

Hi Shawn,

Well, i've read those resources. I couldnt find any clue about whether the impact on SERPs or in any case those tags would help.

Have you used them? Do you find them useful?

GR.
PS: thanks for the response

Those are optional lines in the Sitemap and are handled differently per SE.

Some great resources on best practice:

Reviewing Google's documentation they don't include them, which to me confirms what you've probably seen and that is they don't provide any value. Google's example does use image:captionthough which probably is treated similarly to alt text. </image:caption>
