Google On The SEO Impact Of Dates In Title Tags
An SEO expert who’s working on a website that reports on currencies asks Mueller whether he should include dates titles when writing articles about changes in currency values. Mueller’s thoughts on title tags are as follows:
Mueller says that you can include dates in title tags, but this does not affect SEO. While it might seem natural to have dates as headlines in news stories, Google offers several determining the publication date. We try to figure out the primary date of news articles just like we do with news articles. We do this by looking at all the mentions and other things on the page.
Using dates in page titles is not good or bad for SEO. You can include a date in the page title if you believe it will benefit searchers. Remember that dates shouldn’t be used if there is a significant change to the content or new.
He doesn’t think you would get any magical SEO bonus from adding the date, but it’s OK.
“When you write something new, or significantly change something existing, then change the date. Changing the date without doing anything else is just noise & useless”.
In conclusion, adding dates in titles doesn’t positively or negatively impact SEO.
