Time lag to see effect on rankings after a good optimization

[inhouseninja]

Once you do an optimise / make some (hopefully positive!) changes to pages re keywords etc - how long does it take for you to move up the rankings  - if indeed you do actually  move up...

I made some changes last week and see some slight movement this monday - can I expect more of a movement over a period of a few weeks?  Or does it take longer?

Maybe tricky question to answer  but hopefully you know what I mean...

In addition to Dan's answer remember just because Google has seen the changes and taken them into consideration there is no guarantee that your rankings will improve.

It can take months of optimising and tweaking to get improvements. One of my old sites took 6 months tweaking and steadily climbing the rankings until it got to number 1 for its main keyphrases - it has been there for a few years now though

I hate to always say it but it depends. Google may crawl your site all of once a month. If that's the case, it will take a month or so until you get updated in the index. If you are frequently crawled, then you should get updated in the index much sooner.

You will also only increase in ranking if your site is not penalized. All the optimization in the world won't help a penalized site.

Check your listing in Google and see if it reflects the changes you made. If so, Google likely knows of the changes and within a week you will move around in the SERPs. If Google hasn't indexed your changes, well, it will be as long as it takes until they do.
