Can I get similar results to a SEO specialist by doing the work by myself?
You want to keep your money and do the work by yourself? No problem.
Some people who have never been SEO specialists get excellent results on their website.
A good knowledge of your products and the expectations of internauts are valuable assets.
You also can fix your washing machine by yourself or even build your own fireplace if you have the skills.
Then the matter of time will come out. Some websites have a full-time SEO specialist.
In order to get results, at the same level, you certainly should take as much time.
Finally, a SEO professional is likely to complete some tasks very quickly and invest in various specialized tools.
Anyways, it is to be hoped that a SEO specialist will be more efficient than a beginner. If not, then they probably are scammers.
