An apparatus comprising:

• at least one processor or a portion of a processor and at least one memory including computer program code, that when executed by the processor, cause the apparatus to:
• receive a document identified by a uniform resource locator, the document comprising document content;
• cause display of a part of the document content, the part of the document content being less than the entirety of the document content;
• determine an impression rating for the part of the document content based, at least in part, on the display of the part of the document;
• determine that the impression rating satisfies an impression rating threshold;
• and
• cause indexing, into a search index, of the part of the document content with regard to the uniform resource locator based, at least in part, on the determination that the impression rating satisfies the impression rating threshold.

• cause display of a part of the document content, the part of the document content being less than the entirety of the document content;
• determine an impression rating for the part of the document content based, at least in part, on the display of the part of the document;
• determine that the impression rating satisfies an impression rating threshold;
