This is good advice.
The photos are good but there are 50 million photos on Alamy and you need to get yours seen - the answer is in the keywording in which I would include the captioning.
The captioning is important for 2 reasons - mainly because when picture editors are looking for subjects they need to have the full details of place, name, etc right in front of them. Less importantly, the caption field is searchable, ie. the words have value in the keywording of your images.
In the keywording itself, which is hugely important - get it wrong and the most wonderful images will not be seen.
Examples from your images:
E6CFAB: captioned "Fortress in the Greek Islands" - What fortress? which Greek island? - Picture editors will rarely want general images of fortresses in the greek islands - much more likely they will want an image of THAT fortress or an image from THAT island
E6CEM3: captioned "A windy day at Qaitbay, in Alexandria, Egypt. What is Qaitbay exactly? You have keyworded it as a fort and a fortress, but actually if you Google it , It is called the Citadel of Qaitbay. Use "All of Alamy" to see what searches have been done in the past year - there have been no searches for "Qaitbay" but one search for "Alexandria Citadel" and your image would not have been seen.
You have only just started so I hope you will not feel this is being too critical - hopefully intended to be helpful. With so few images on sale so far you have the opportunity to improve the captions and keywords of images that are already there.
BTW be aware that images with people or parts of people in, whatever their size and whether they are recognisable or not, cannot be RF unless you have signed model releases for all people in the image (cf. image
RF for example), and also images with property taking up most of the image cant be RF unless you have a property release (cf Image
E6CEM3 for example)
Good Luck and enjoy Alamy - it is usually good fun
Thank you so much Kumar! This is very helpful and I'm revising my captions/keywording now!
