I know that the recommended meta description length should be between 150 and 160 characters.
However, on a website I am working on I have to make use of various php variables to make them "sort of" unique from each other. There are thousands of links and I cannot edit them all.
Because of this, some of my meta descriptions end up about 90 characters for example.
Will this raise any concerns ?
Do you recommend it would be better to leave them blank instead of just 90 characters.
Even though they are just 90 characters, they are actually relevant to the page content, saying exactly what the page contains.
"Buy $product from $brandname online. Only on $oursitename you can find more similar products."
So, as a result:
"Buy big red appels from Aswesome Brand online. Only on Example.com you can find more similar products."
I could of course increase the common text length to reach a minimum of 150 characters depending on the average product title length, however the common to unique text ration would go down in this case.
What would you recommend ?
