If you have been through this guide and carried out the work involved then give yourself a wacking great slap on the back! It is little wonder, considering the mammoth task SEO involves, that many companies contract it out to people like me.
At some point it will be time to start the process again.
But first you need to give your work time to show through. Different search engines will pick up your changes at different times and they will re-index it within their search results today, tomorrow, next week or next month.
If your website was being found for the wrong reasons by the wrong users you are going to lose those people. This means your traffic volumes may drop for a while before picking up.
Many who go through the SEO process properly see a drop off of traffic overall but an increase in business or conversions which then builds solidly. They do however, have to handle a deathly silence inbetween ...
There are plenty of tools like Google Wemaster Console and Google Analytics which will tell you early on if you are moving in the right direction.
If you really want to, SEO can keep you busy all the time. The need to write more articles to post on other websites, take part in or dream up new ideas to write in a blog post - it can take hours out of your day.
So SEO needs to be put in it's place. It is part of a marketing strategy. How much depends on your business. There are other avenues even if all your clients come from the internet.
Don't forget directory listings, forum discussions, Q&A websites, Social Media and the whole world of online marketing beyond search engine optimization...
