Image TITLE Attributes
We do not therefore recommend using Title Attributes with image links to try and boost SEO.
We do however still recommend using them if their use will convey to website visitors something useful about the landing page.
If the latter is not the case then there is no need to add a Title Attribute to the image link.
IMPORTANT NOTE ABOUT IMAGES & SEO
TITLE attribute adds NO VALUE to SEO.
ALT attribute adds SOME VALUE to SEO.
IMAGE FILE NAME adds MORE VALUE to SEO than either of the above.
IMAGE CAPTIONS will help reduce BOUNCE RATES.
