So I have a relatively small website (40 pages) for a local service based business. So say I get click rank to crawl and optimise all 40 pages. If there are google algorithm and data changes in the future do I have to use more of my crawl "quota" to re optimise those 40 pages or do I get those 40 pages optimised for life of the page?

Sorry if you've already answered this question but I found the previous answers unclear

Thanks
